Laminated the keel today. Took 5hrs to laminate then vac bagged it. Will find out tomorrow how well we did with it. Should have te foils done in the next fortnight. Then onto pouring a bulb.

Can I ask how many layers of biax and unidirectional glass did you use? On a keel and a rudder?

Keep up the good work! How long do you estimate the building will take?

[Tokyo Trash Baby]

About 10layers of carbon uni a side. Then 3 layers of biax on the keel.

[Nrg85]

Interesting.
I have heared that before from people for rudder and keel.
Is it so common for 6-8m sportboats to have roughly the same layer?

10 layers of lets say 200 g/m2 unidirectional carbon and that 3 layers of biax seem a lot to me.
Or is it unidirectional only 10 cm (about 4 inches) wide and one layer over another so only 3 layers of biax are over the whole thing?

This boat seems to weight similar like i550 but more powerful, it should give more speed in every direction, especialy upwind.

My 2 away boats went well on weekend. Charles Baker, a mate and my 2 adult crew took, line, handicap and class in my Spider 22 Bobsled finishing 40 Min in front of next boat in Pearl challenge in 25K northerly. I sailed Slingshot in Heaven can wait with Sydney crew in a wild 20 to 40K westerly. The boat was not good , it was brilliant. Because crew had no Slingshot experience, we decided not to run a kite even though our fractional is easy to use. With full rig the sails set well. rarely inverted, little back winding being footed off a bit, we were very quick compared to other boats. Had we used our kite the race was ours for the taking. We only did the 1 lap pulling out of 12 and 24 hour races. was happy with 2nd out of 28 boats that finished. Finally got a score up.
Even with lots of advice and help there has been no quick fix, of poor upwind speed, and not enough time on open water. Last SBS at RQ found direction, the mast has same rake and bend as before, when sails would not work, but do now, all about fore stay sag.
Grahame has some mods for my sail but going to wait till after next 2day Manly regatta to get best out of where I am Now.
Good to see the builds progressing, exciting times for you Guys.

[noosa special]

Tokyo, I do not have contact details so this may do. If you are going for the 2+2 option on bunks as I did, there is really not enough room for 4 people unless very small as Dan pointed out.. The coffin bunks are great to store the crane etc.. There is plenty of room for 2 good bunks especially if you make a removable infill foreward of compression post as I have. and a boom tent will look after other crew if required. To have the coffin bunks the deck floor is carried right to the front bulkhead. I now realise a mistake but a huge job to rectify as you dont have enough head room to sit on bunk , It may compromise rigidity but if bunk was 150mm lower would be great.. This is no criticism of the design the bunks work fine as is but there is a big difference between functional and great. To make a 150mm step at cockpit bulkhead would be up to Dan , If I had my chance over I would make the change.

Almost finished sanding hopefully - the painter guy is coming around tonight. I have some beers for him - surely he will let me stop.

Keel vacuum bagged last week, looks great, not to much fairing I think. Found someone to pour the bulb as well. $600 plus I supply the lead - seems good to me.

Maybe launch in January is going to happen.

Thanks Bob. we will be using the quarter berths as storage mainly and plan to sleep two in the cockpit and two in the boat so quarter berths wont be too much of an issue to us. Glad your starting to get your boat sorted and going

[Tokyo Trash Baby]

Keel is now ready for fairing, after bagging. thought there would be a lot of bits to fix up after we tried so hard to fuck it up but the bagging process does wonders to making the glass and carbon conform to the shape you need! The amount of resin that came out was incredible, you don't realise how much resin a big laminate takes up until you watch it all come out in the bleeder.

Looking good! Bet your glad you are coming to the end of fairing the hull?!

[itkiwi]

Halyard setup - can someone tell me if a Harken 150 cam cleat is the go for mounting on the floor for spinnaker halyards - are they big enough not to slip?

Second thing - if I cleat the main and jib on the mast with the same cleat will that work? Possibly with a cheek block first to turn the halyard run back 90 degrees and then the cleat so I can pull aft on the halyards. A picture of someone's setup would be great.

The painter guy said I can stop sanding and put some duropox undercoat on. Temp is 5, raining and possible snow - maybe not this weekend.

[Tokyo Trash Baby]

Depends what size rope you are using and what the jaws of the cleat are like. I remember I had a harken cam cleat holding my tack line and the jaws tapered back out at the bottom so it never held in breeze, ended up double cleating it then reverted back to a ronstan swivel cleat and all was sorted, the rope was only 6mm so problems probably started with the rope size!

do u reckon u will have it at the donald hay in feb?

[Young Rocketeers]

i had cam cleats holding the spinnaker halyard & tack line on my boat. They held fine, i did put some stitches through the lines for a meter either side of where the line sat in the cleat so the inner core didn't slip in the cover.

this issue i have with cam cleats on halyards or tack lines is they're very hard to release under load. i would consider a small spinlock clutch like an XAS that's what i changed to simply so anyone can dump the halyard if they have to no strength required.

Got to agree there! Easiest set up and easier on the crew. For all the weight and windage you might save with 5 or 6 mm halyards you will loose it all with one slipping cleat or a jam in the smaller line. Too many people over-think boat set up!

We have 2 to 1 on Main and jig halyards, single on rest, all either 6mm Spectra or D.Braid. No problems using extreme angle 150 cleats so far.
It is difficult to pull lazy sheet through aft block when jibing and has to be fed and eased through even with ratchet off, 8mm could be difficult.

One thing ASBA has gone hard on is Squaretops, our rating went up 21 now same as Magoo. Never liked it and believe responsible for our problems up wind. Not a problem now as cut it off and will request re rating.

[Turkey Slapper]

You will find it wasnt the ASBA that went hard on the square tops, the SMS mob at YV do it fella!

Yor boat wasnt that far behind us last time we raced, wont be long!

lets get rid of the mis info

Are you saying that YV has changed the rating of mainsails

or you changed mainsails from a conventional to a Sqr Top
-------------------------------------

yes YV is hard ( too hard) on all kinds of 'big roach' but that is nothing new and precedes the Leech being launched
They take a 'headboard width' measurement which is stupid IMO

you are suggesting it has changed recently to 'more penalty'.

any other reports or sqr top boats that went thru the roof ?

[Tokyo Trash Baby]

Sounds to me like he cut off his squaretop. Not the other way around.

[GybeSet®]

no that doesn't make your rating go up
it reads that that is 'the cure'
his rating is high now on the YV list

what has changed ? SMS calcs ?

[oregami]

Info we received.

"Yachting Victoria (with input from ASBA) have amended the SMS handicap system for 2012/13.  The outcome appears to be an increased penalty for lighter displacement boats and upwind horsepower.  Some of the changes are:

Arnt the vipers the fastest things on the planet?

Thats what we keep reading!

Some of the brisbane races lately have real close results, as the Fastest Shaw and Leech in the universe race here, and its been seconds between leech, shaw and T7, where finally it has been up to who makes mistakes loses, how it should be! Peow is still dificult to beat once the breese in, but its way closer now, and just mabe if they hit a couple of the fringe boats we4 might see some of the older fleet come back and the numbers grow again!

[oregami]

I hadn't heard that....

Thanks for putting the word out Slapper.....

Sounds like good racing in Brisvegas

Unfortunately they hit the T7's (eg The Fifth 7 went from .810 to .815) and 750's in the Perth fleet so it will still be hard for them.....we need to encourage these current owners, to build the SMS fleet

[noosa special]

To clarify have cut 1/2 of square top off Slingshot main with other mods. Will try tomorrow unfortunately at Noosa. More work may be done before next RQ SB SAT and re rating. Some interesting comments since my last post.

[oregami]

Shaw 650, Octopussy probably went up the most (0.017), because of a change of owners and philosophy...change from smaller sail area to larger sail area so a large change in rating.
Octopussy has probably just moved more towards a standard Shaw setup and rating (.823 - .827), although at the lower range.

Shaw 650, Shaw Thing (who co owned Octopussy) stuck with smaller sail area, so kept the lower rating. (now .800)

The E 7"s seemed to go down roughly .007-8
The Young 7.8 stays about the same

Vivace goes up .006
Shaw 650’s go up about .008
Raptor goes up .009
Kiss goes up .012

Shit…the Viper 640 goes up .013 … as far as I can see, the largest change in rating...?????

Gotta love one design…

[oomummado]

Cutting half your mainsail roach off seems a knee jerk reaction. How much slower are you going to be with that? Rate low go slow. You can't just cut roach off. Rookie error. You will need a whole new mainsail to be effective otherwise you will keep on going around in circles blaming your equipment for lack of performance..... An old guy once said.... A poor workman .......

[oregami]

Ouch, that increase hurts and then hurts some more.....
It must be a couple of things they've hit (weight and square tops) seeing we don't have a square top main.

[GybeSet®]

Noosa, do a trial cert fer goodness sake!

there are more factors than just roach going on here
e.g. The Vipes did not have a SqrTop

[Turkey Slapper]

The shaws and leeches and the rest of the light boats had an advantage and hence have been pulled back a little in sms numbers, still only seconds per race! Chopping sails down on the small rigged leeches and shaws will kill them even more in the light conditions where they have there work cut out anyway, and in breese can still win easily with the big sails as the pair in Brisbane show! It worked on the T7 cause our sails are so big anyway. As for.the viper, results we have seen say they win as they are now, or do they not race true sms regulations yet?

[Tokyo Trash Baby]

Yeah, sounds like you are getting way too dramatic. Get your boat up to pace and finishing with boats it should be consistently before you go chopping and changing!

[Turkey Slapper]

exactly, noosa boat isn't far off, but being heavier and less mainsail would kill it in under 12 knots! Heavier older designs still need a bit more grace before I think they will come back, but its getting closer, some of the extreem end boats, at both ends are the ones needed to be looked at im thinking! The middle of the fleet is good close racing at times, with only a couple of adnormallitys!

[Hobbs]

I keep looking at all the SMS rubbish and just keep wondering what is going on! From the racing I have done there is some very good close racing and some results that are out of place. There are some very good boats and sailors going around so it is unrealistic to think you can just show up and get a win. You have get the boat working well, sail well and not make any mistakes around the course to win and even then it will be close.

Some people seem to focus only on the rating and forget that the most important things is to get the boat going fast as often as possible and then you can beat your rating with good sailing.

Sling Shot is a great example. It is not far off the pace as it is. Given the modifications from the 'standard' Leech I think they are doing a great job and catching up to the fleet quickly. This is only a new boat for a 'one off' set up that is different to what the owner has had previously so it will take some getting used to! Any modification will lead to a new rating but that will not change the game. Sailing the boat more and getting used to what makes it work in different conditions will get you sailing closer to the rating, regardless of what the rating is!

[GybeSet®]

Old shipwrights rule
measure thrice, cut once

in this case 'consider' thrice ?

[Hobbs]

In regards to the 'extreme' boats, I think that the rules as they are need to be more strictly enforced along with clarifying the self righting rule and have random testing of the rules as events. I have seen extreme boats in all sort of trouble in racing conditions that we regularly experience and that should never be the case!

The extreme boats will put people off racing sports boats.

The first race of the RQYS Sports Boat Saturday Series is a great example. Raptor beat Peow by almost 2 mins on corrected time. Raptor was late to start and went the wrong way up the first work. Peow had a blinder of a race and beat Stay Tuned by about 2 mins as well. The rest of the fleet (including Sling Shot) were all within 1 minute on corrected time! There were some good sailor on Raptor that day but to say they were 4 mins better than the fleet after missing the start is ridiculous!

In the next race the rest of the fleet (which include some very experienced and successful sailors too!) got around the course in a building breeze while Raptor hooked the inner top mark on the way upwind and could not get unstuck. It looked downright dangerous while they were trying to get unstuck and in the end they had to pull out of the race after send a crew member over board to get loose.

The boat is so 'extreme' it could be considered dangerous in anything other then benign conditions! There is no way the ASBA should have rules that allow for such a boat being so far removed from the rest of the fleet!

What makes the boat so extreme as compared to sports 8??? cause you can't beat it

[noosa special]

Wow we have some interesting comment going on here which I seem to have started. About time this forum had some spunk. Seems most people know more about the Noosa Boat than me which could be true, anyway all comment can only add to my ability.
So lets go back to the start post Bay 2 Bay which was a down hill run.
This is extremely difficult as I have the greatest respect for Grahame( Evolution Sails) and consider him a great guy and friend, I hope you guys are adult enough to understand my problems. If I lived in Bris or Gold Coast would be great to work with Grahame. He has taken the leech in a very short time to the front. I have no doubt it will not be long before he is the boat to beat ,he has the ability and resources to do so. he is the man to see for you guys down that way when you get boats finished. I am just too far away. We made our sail as developmental ones, not conventional, and knew would not be a instant suit.
We both had identical sails, my 1st trip to Gold Coast for tests had my boat slightly faster upwind, ( the sails were purposely designed flat) Next trip to GC we put in a lot of work, changed to full lower battens, Later a re cut luff, the boats were not competitive. Grahame did 2 regattas and turned up at Race week with new radial cut Jib and main. He had made a big improvement which he has worked on to be up the front now. My big problem is it is a 500k trip to GC and can not expect Grahame to come up here , which he offered, also we can not sail in Noosa River with board fully down and wind disturbed by buildings and trees. So development has been difficult.
So re rating may be good, but the re cut main was about performance not numbers. I was surprised when we hoisted altered main to find it is a pinhead. No more full lower battens which Had the draft too far aft. The Square top which was a flag with draft against mast is thankfully gone but sail has lots more power which is easily flattened as wind increases.,
It is hard to tell with the board up in our creek but for the 1st time we had a main that looked it would work and powerfull, we have some very good Blazer sailors here and for 1st time we were much faster up wind close hauled than them, we need to make a few adjustments as mast too straight trying to get some shape in old main but i believe we have turned the corner. the extra 100kg in our boat is no excuse for not being competitive on a beat.

[MSA]

Full battens in the lower 1/3 mask luff curve issues.

So you cut the sail down and now it sheets on and you can sail up wind... Seen that happen many a time.

Sounds too me the large main was to much load for the rig... Maybe increasing tube stiffness as well.

One of the Shaw 650's had the same issue here with an Evo main.. Same thing, was converted to full battens and had a luff recut.. Next mainsail had a smaller head width.

[Hobbs]

What makes the boat so extreme as compared to sports 8??? cause you can't beat it

Note: I abbreviated my comments above so not everyone has to keep reading them.

Frank, I used the term 'Extreme' as I believe Raptor has been designed specially to one edge of the available rules and taken this aspect to the limit. This being the weight. Extreme is not an insult. It is a description. In this case, Raptor has be purposefully designed to get a rating advantage. There is nothing wrong with this and a good rule needs to evolve in these situations to ensure the fleet remains relevant. If you go to far with this you end up with a boat that may not handle all of the conditions that we race in. Sailing is littered with stories of these types of boats.

There is nothing new in this and in many rules over time they have developed to such an extreme that the rule becomes useless and the owners and sailors move on to the next big thing. IOR and IMS are examples of this.

I would hope that the sports boats can steadily modify the rules that are in use to keep the fleet result close as they recently have so that all the boats remain relevant to the result. That is the way to keep people in the class and bring people in. At the moment, if a boat at one extreme of the rule dominates in certain conditions then that should be a concern to association and the rest of the fleet.

With regards to a result, it is not so much about winning/losing. It is more about the margin. No boat should be able to win in this type of rule unless they sail an extremely good race. Given how close the rest of the fleet results have been a poor set, a bad gybe, poor tactics or a missed start would cost you places. The rules should be able to evolve to take new boats into account and keep the current fleet from becoming obsolete due to just one boat.

BTW, Mark has contacted me and made some good points as well. He knows who I am and I am sure will have the chance to tell me what he thinks again.

[Hobbs]

Noosa Special, I hope you don't take offence at my comment. I like what you are doing and I have been impressed with how much your boat has improved. I have been looking at different sports boats and I have discussed the Leech with Dan and several others. I had a good look at your boat under constructions and went to see Graham a couple of times during his build as well.

It is up to you how you develop your boat and I am sure you will have plenty of fun along the way.

There were 2 that fell over that day, shorty the Eagan 6, which later lost its rig as well while getting towed and Raptor! The shorty looks all fixed and ready to sail again now!

Thanks, now I understand the spirited comment.

Got boat into the building after being away from the project for a while. Bagged down the chainplates as per Dan's instructions. the lines on the table were to get the uni running in the correct angle for each layer. whole process from start to finish when the bagged had pulled down was about an hour and three quarters. Foils will be undercoated this weekend and looking to have them glossed by next week, along with our mould to pour our bulb.

Does anyone have a link for some non-skid sheeting for a cockpit sole. Treadmaster I have found on the web but it is 2kg per square meter. There must be a lighter product out there. I would rather not use one of the paint systems.

Thanks

We have this: http://www.noskiddin...m/ns_ns5200.htm
Its the same stuff that you see on most of the big racing boats.

Check out the Raptor deck...looks like cool stuff. http://www.raptorsails.com/

We used glass beads and 2pack on Slingshot, Looked great but proved slippery when wet. Have installed J P Bowers of Gold Coast EVA dogbone deck tread same as Stay Tuned. Dos not seem heavy. Still to use it in high winds.

Some progress - off to the paint shop today I have spent the last 6 weeks sanding back the duropox undercoat. Horrible stuff - easy to sand but the fine dust goes everywhere.

Rig and sails are supposed to be here this week - I might beat Geary into the water yet.

Brilliant stuff. To bring your boat to construction finish in the deep freeze of winter and spring there, with high tech materials is pretty special , I employed a very skilled boat builder here at noosa , rarely below 25deg as summer build, but was not easy. If you sail as well as your build skills a lot of fun is to be had. Well done.

Where did you guys get your receiving tubes and prods from?

Where did you guys get your receiving tubes and prods from?

The rig including prod came from Southern Spars. Currently all of this is on a truck somewhere between here and Auckland.

All the other tubes of various smaller sizes came from c-Tech. The bigger of the two receiving tubes is carbon but might well be made out of e-glass - to me it appears only there to keep the water out.

Thank you Noosa.

Getting rid of the mains square top which did not work and making it a roachy pin head with half width and lower left the same and no other mods made to boat, has changed our SMS from 815 to 800. New rating issued today. I Gotta be smiling.
Looking forward to Sports boats SAT tomorrow at RQ

Is there an option to build this boat without carbon fibre?
Only e-glass?
How much heavier would it have to be?

[Tokyo Trash Baby]

anarchist "sporty" is building one from glass i believe. maybe he can shed some light on that for you?

Mine is carbon hull e glass everywhere else, aproxamate weight to price is around 15kg extra in the hull for around $4000.00 saving, no brainier to me, just ask Dan Leech to draw up what you want, this was my brief for the build. Hope this helps

Poured it as one unit, with the mdf covered in glass acting as a plug for where the keel will insert. the two glass halves were bolted every 30-40 mm around the whole perimeter of the mould then put into a sand box to support it when the lead was poured into it.

What is the weight of the bulb? If I can ask?

[Tokyo Trash Baby]

110 according to the design. we didnt weigh ours as we didnt have anything to weigh it at the time

Sorry for my ignorance but did you make a fibreglass mold then fill it with the molten lead? I'm not sure if I'm seeing it correctly. Do you use special resin that's heat resistant? I would have thought the resin would burn off but I've never done anything like this.

Epoxy resins does not burn when melting lead.

We used vinylester resin for the mould

[Jethrow]

Cool, thanks guys, I'll file that away in my memory banks for later...

[itkiwi]

My one came back from foundry at 134kg. A bit more than planned but was made wtb cnc cut plug

Thanx, I will contact him.
15 kg really isn't much extra weight, at least not for me and for that cost savings.
I assume that you put carbon just on the hull inside and outside and everywhere else e-glass.

[Nrg85]

TTB so you did use fiberglass and resin for mould? Rowing fiberglass or chopped strand mat?
Similiar to Jethrow I also tought that the resin or fiberglass would burn off if pouring hot lead into it.
Any more info about that, would that work for bigger moulds for pouring lead as well? Maybe someone knows some useful page with some info about that.

Spot on! carbon in and out on the hull e-glass every ware else.

Chop strand mat shot from a gun with vinylester resin I believe!

Vinylester resin is the only one that will cope with the heat. Epoxy will re-soften around 54 degress for the average one where viny is much higher. We just did a 2000kg bulb with hand laid choppy and vinny of about 10mm thick and into a concrete support box. Sand may have been alright, but we added a bit of HTFU stuff to be more resiliant. The stuff stinks with the first pour as it post cures but we did another one which was clean as!!

[crossa]

we used casting plaster for the mould and layered fbreglass tape around the mould to retain shape when we split the mould to get it off the buck, them recoated in more casting plaster after we sat the stainless frame to attach to the foil, then we sat the whole thing in a box filled in sand, which we compacted well and then melted lead in a huge catapiller bulldozer sump above it and then poured it, had no distortion at all , easy as !!

[fullsail]

The set I had when I poured 800 pounds of lead. The mold was 3 layers of six ounces fiberglass in epoxy resin. Maybe the resin got soft, I do not know. But even the lead shrunk or the mold expanded, there was void between the mold and the lead. I cut the mold off, faired with car putty and recovered with glass.
