Good vid Stealth  :D

Ready for the rig now, getting fitted next week. Newly mounted outboard rack thanks to Michael James who makes these for the VX ONES. Works perfectly on the Tohatsu 3.5 If any one wants info on these send me a PM and i will pass on his number.

Cheers

I thought the older timber shaws had some flex in them (forestay would sag a bit downwind, glass ones don't do it as they are stiffer), the Slingshot is really getting some serious bending going on to get the forestay that loose on a 6.5m boat with basically the same rig as a 650!

Looks really nice and fun blasting downwind for sure!

Not sure about the woodie Shaw's not being stiff as the glass ones? Vinyl ester Vs Epoxy..Hmmmm?

Leech looks great, forestay tension would be a worry for me, much more rig tension needed, or a new boat if it flexes that much.

Thanks! Not sure need to build up the funds again for the rigging. I already have the mast, boom etc off Dans plans (C-Tec) but need to fit the boat out and rig etc. If the rigger and the lead bulb dude get some free time early enough in the new year I might just make it but well see,CheersDamo


Damo,

How big is the bulb and when are you getting it made and what sort of dollars to get it made ?

Pulpit

Just received the Bulb back from Qualcast here in Burleigh Heads $770.00 inc GST Total I just supplied the plug. and aprox 1.0mt long

yeah I doubt the boat is at fault in that video, more likely the rig set up.  A modern boat, built with modern materials just won't flex that much

didn't comment on the woodies in general, rather the two older timber Shaw boats we knew of both of which originally had less structure in them (Pornstar and No Limits) which was also a little prone to damage in front of the main bulkhead (3mm ply), resulting in a slightly bendier boat as the ply would bow out to one side.

Back in the day, we could set the Pstar rig to run 300kg rig tension and still the forestay was looking like that downwind. I know the P8s also had a saggy forestay downhill.

In both cases, at a later stage the PStar and No Limits were refurbished and for Pstar it meant replacing the bulkhead running fwd (as all the structure inside was no longer doing its job) and had more structure put into them as per the original design, and that stiffened it up a lot; the glass boats have a pretty beefy X frame running aft and also forward of the main bulkhead with a very solid base under the mastbase, plus being a thicker foam section than 3mm ply in the stringers; that's where the stiffness around the maststep to chainplates comes from - it's not vinylester vs. epoxy or foam vs. cedar but rather amount of structure in there. Should be no reason why a timber boat is not as stiff (or stiffer) than a glass one for this type of boat.

Maybe my original post was a bit misleading; would assume that a bit more rig tension would hopefully make this issue disappear on the Leech also.

Thanks for the explaination

I didn't quite follow Rob's plans in the front.  I put a much stronger stringer running along the centreline from the mast bulkhead forward to the first bulkhead.  I think 4mm ply that was specified was just a bit too prone to finding a way to flex in compression which is what forestay tension in doing.

Finally "Raw Prawn" was launched last Saturday with only about 6 knots of breeze but that wasn't going to stop me after 2 years of building!!. I would like to thank the following people for their support and help through the build process.

  1. Dan Leech for the easy CNC kit plan set, phone and e-mail support. For the home builder this was fantastic and went together like a jigsaw puzzle. With my next build this will defiantly be the only way I would go after working on this build "Thank you Dan".
  2. Graham Sheering at Evolution Sails for the advise during and still on going with the rig and sail tune not to mention great sails.
  3. ATL Composites for the CNC kit and help with the build advise.
  4. And Last but not least is Peter Green Boat Builders for the help with the structural parts and the fairing/Painting of the hull.

Just a few pics of the launch, hope to have some racing in a blow next time

Cheers

Damo   :D

Awesome - congratulations - I should have been this bold with the paint job. You will have so much fun. They are tough wee boats too. There is a keelboat here with a hole in the side slightly larger than the sprit. On his starboard side I might add.

 

Some traps are the way to make it go too - even if you are not allowed to use them in ASBA events.

Just a folding set up. Get rid of the clamp off the outboard, bolt the arm(not pictured) to it, then bolt the other arm to the middle lugs . Just allows the outboard to be folded up into the boat to get it tucked away and weight closer to the centreline.

It is a year now since last Airlie race week where we learned so much about the boat.. We felt the cabin was causing a rig dynamic problem not apparent on the flat decks as we could not match the J7 upwind over 10K. We moved the mast step aft which allowed us to get rid of some rake, back to where Dan advised,  reduced working sail area to just under 25M as we have a light crew of 270Kg.

  With help from Vaughan at Norths we tuned the mast which was a mess, difficult to stop the excessive pre bend we were using. Got rid of the adjustable caps, went for simple and put back to Dans original cap design.

  This was all good but were still not right upwind it had to be a crew problem. It is funny how unexpected help can occur and came in the form of Raw Prawn at Mooloolaba. The penny dropped when we saw the photos of our 2 boats together and Damian with a crew weight of over 400kg against our 270kg.

  It is hard to find photos of boats sailing upwind, There had to be some reason why the Audi Shaw is almost unbeatable, in 6M class, it is no different than the other Shaws, We found a few pics, it was obvious how superior they sailed their boat upwind in any pressure.

  We went to Airlie with a new outlook on how to sail the boat, we are quick in our Blazer23 but that style was wrong for Slingshot.

  We had no experience of skiff sailing, was all strange, we thought we would be low but didnt seem to be, we had no experience of this style of steering but adapted, we could now hike hard and make a difference, was brilliant, we now understood how Slingshot worked.

Dan designed Slingshot to be a complying CBH boat and did a fantastic job, It took me a year to understand just how good.

  Airlie was one of  the best regattas I have ever sailed, we sailed in Trailable fleet which had 10  8M class boats, We matched the boats up wind and had a whisker more height but all very even, the only place we could claw back some time for our higher handicap was with our very superior off wind pace.

The 6 days were SE20/33K  mostly 25/33K, We did not have a reef which would have helped. The boat reveled in the strong winds, the main only inverted in the strongest gusts, generally we used our fractional assey, and every day we had incredible rides. On the thursday off pioneer rocks in recorded 30/33K against the tide our 6th jibe didnt work spun down and took 5min before we were off again. with only a 90kg bulb the boat was safe, and puck had us doing 4K against the tide, this boat is fast it does 6K laying down going sideways.

 There was lots of pics posted from other boats of us sending it big time, was hard to get the grins off our faces.

  We were pushed into SMS earlier which was unfortunate, there is no allowance in SMS for the wind drag of the higher hull, cabin and space of cabin where the jib should be. Was great to race CBH we belong there and will never race SMS again except maybe Bay 2 Bay.

If you are not keen on the ASBA  W/Return form of racing, and want to race CBH with a spirited fun machine Dans the Man.

Hope to see the new boats at St Helena Cup be nice if it is SE 25/30K.

Deck gear is on now, mast track is down so we can roll the boat on its side with the mast up so Ullman sails Brisbane can accurately measure prebend for the mainsail. A heap of small jobs to do to get her on the water, which is slightly painful but rushing isn't the way forward. Prodder bearings to still make and end plugs, rope systems to run, bulb onto the fin and get the flashy mag wheels onto the trailer! Amongst a heap more.

Checked how the keel fits and the rudder. Got an accurate prebend measurement for our sail maker at Ullman sails brisbane and any other measurements he needed. Bulb has been fitted to the keel as well. Still a lot of little jobs to do, but hoping to make it to st Helena cup to race the other leech 650's :-)

What a little weapon! First sail was our first race. Mild conditions 10-12knots all weekend. Saturday we finished in behind the two thompsons(7m&650) with a vxone in front and behind us. Sunday saw us being the first non-winged sportsboat to finish. Awesome kite ride from the top mark really showed us just how much potential this boat has. Dan has really designed a great little sporty for amateur construction and we are absolutely thrilled with how she performed straight off the trailer with no sailing time under our belts. Can't wait to rack up against the other l650's and see how we really perform. What a boat! Really stoked!

Congrats to the DC Ethel crew, the boat was great last weekend straight out of the box. We were impressed with the good upwind pace and Robs ability to sail the boat flat, Skiff experience I expect. They will be on the pace when they meet the Gold Coast boats.

For Slingshot crew was a gift. Our lifting center board is nothing like the standard boats, being 50% longer front to rear edge and more than 50% wider and same fore aft width to within 600mm of bulb. I have never seen the standard board before till DCE as only seen Grahames boat in the water.  Our problem has been solved. We could not compare with the flat decks.as too different.

   Will hurt to have to cut our foil shaped cassette out and put in a box, the boat will never sail again in Noosa Creek, but will be getting a conventional SB foil. Was a mistake to make an all round boat.

  Moving the mast countered  the lack of lift from the CB and enabled us to sail in stronger pressure and get some helm, will be interesting  to find if this is a plus or has to be move to original position.

I would like to clarify one point re the CB.  The boat was designed at my request to have a lifting board with a 150Kg Bulb to race CBH and have a large stability factor. The CB needed to be strong.  We have now fitted a 90KG bulb  so possible to use a much lighter one. The stability is still OK.

Congrats to the DC Ethel crew, the boat was great last weekend straight out of the box. We were impressed with the good upwind pace and Robs ability to sail the boat flat, Skiff experience I expect. They will be on the pace when they meet the Gold Coast boats.
For Slingshot crew was a gift. Our lifting center board is nothing like the standard boats, being 50% longer front to rear edge and more than 50% wider and same fore aft width to within 600mm of bulb. I have never seen the standard board before till DCE as only seen Grahames boat in the water.  Our problem has been solved. We could not compare with the flat decks.as too different.

Keep us posted about the mast position.
