JL92S 426 Posted December 11, 2018 Share Posted December 11, 2018 Verdier has designed a funky looking hull here and pretty distorted in places. It’ll have stiff competition from the JPK 1030, J99, Ofcet 32, MAT 1070, MMW 33, new Nivelt 34 and the new Beneteau First 35 arriving next year Quote Link to post Share on other sites

JL92S 426 Posted December 11, 2018 Share Posted December 11, 2018 If it’s fast I don’t care what it looks like! I’m hoping to get a ride on the first UK boat when it arrives. Curiously back when Maxi 72 Ran II started to win everything they put a rating tax on the hollows in the stern. I wonder if the bow and stern hollows of the 3300 also incur the same tax...

ZeeZee 14 Posted December 11, 2018 Share Posted December 11, 2018 Likely it's slow and the distorted hull only favors the rating. That seems to be the trend nowadays. Quote Link to post Share on other sites

Is interesting that Ofcet is marketing their boat as a v2 now: less displ, more sail area, different keel and water ballast. The J99 looks to be going the other direction with an aluminum mast, and published displ 700# more than the SF3300. Hopefully JPK will have more out about the 1030 soon Quote Link to post Share on other sites
JL92S 426 Posted December 11, 2018 Share Posted December 11, 2018 The Ofcet has been given the sail sizes, keel and displacement it was designed with in the first place. In an effort to get the boat into the lower irc rating band they piled the weight onto the boat and chopped the sails down but found the boat to be sluggish (funny that...). The 99 comes as standard with an aluminium mast but carbon is an option, as is water ballast, as is a symmetric kite setup, as are twin rudders and all UK boats will be sold with the lead fin keel but the L shaped iron fin lead bulb keel is still available. Interestingly the 3300 is available with two sizes of square top main, I guess the idea is either long bowsprit, assymetrics and big main or symmetric, short bowsprit and small(er) main Quote Link to post Share on other sites

Great. does look a bit like that. the 3200 & 3600 were a success, hard to think they'd be taking a backwards step. assume they're trying to address the stickiness the 3200's suffered from? they've got significantly less beam. Slightly more weight, but added length. Quote Link to post Share on other sites

If you say so - never noticed a hull cutaway changing how a friction ring system works. Cutting the deck affects max beam measurement, reduced weight while allowing the boats to have large volumes at the bow. It might not seem much - but when they carry that natural line from the bow to the chainplates, it sometimes moves the aft beam measurement by a meter. 1 Quote Link to post Share on other sites

It looks to me that it might be possible that the hull shape may reduce the amount of hull in the water when planning The hull shape is designed to promote earlier surfing/planing compared to the 3200, with less wetted surface area and more sail area. With the mast and keep positioned further aft, the jib and spinnaker can be bigger. The twin tillers on the 3200 worked well, except that they were targets for the mainsheet to wrap around!! This won't be the case on the 3300.The design has a downwind bias, good for the Transquadra, but maintains the high stability for upwind work. The hull inflexions are there for hydrodynamic reasons, not as IRC rule cheats. Give Verdier a clean sheet of paper and he always draws fast boats (Comanche, Hugo Boss etc), Andrieu's challenge has been to keep the boat IRC friendly without losing the Verdier sparkle.

Like I said, people are questioning, and the project is very young, so time will tell. Daniel is an old friend who I have huge time for. We shall see how the double concavity gets on. We just don't know. The rig stuff etc is all just normal with a project like this in early days. There is a bit of a juggle between what is necessary for a fluid production run, and what individual owners want. Often takes a while. A smaller yard like JPK, where hull #1 is usually a works boat or a selected client, works in a different fashion. Quote Link to post Share on other sites

Fastrak 67 Posted February 20, 2019 Share Posted February 20, 2019 I can assure you plenty of healthy discussions behind the scenes, but everything is now just about set. Sure, there are compromises to make the series production at a price/performance point that is acceptable and viable, and there will be possibilities for owners with deeper pockets to invest in marginal gains. We have made our choices for the new Fastrak. We are being loaned a boat in advance to verify those choices and the polars. Exciting times! The passion the collaborative design team have put into the project has been insightful. "Dog" .. I doubt it ... this will be a "technical" boat to sail with those who master it gaining big rewards. 1 Quote Link to post Share on other sites

longy 847 Posted March 18, 2019 Share Posted March 18, 2019 IIRC that 'enclosed strut' method for the prop shaft has less drag than a saildrive. And no corrosion issues. Boat builders LOVE saildrives because they are sooo simple to install, the entire system is bolted together. Just cut a hole in the hull, mount a prefab engine mount pan, & bolt it in.

Miffy 2,144 Posted March 18, 2019 Share Posted March 18, 2019 Jeanneau smaller boat offerings often use shaft drives - nothing unusual and in the modern era, esp if vacuum bagging anyway - there's very little extra work involved to deal with a shaft drive, just a matter of the architect's design. Amongst the dockside cruiser crowd there's always a lot of dogmatic opinions re shaft and sail drives - in the end it is just a compromise with pros and cons with each solution. You'll find class 40s with either. 1 Quote Link to post Share on other sites

Alcatraz5768 415 Posted March 24, 2019 Share Posted March 24, 2019 That whole article could have been written about ior boats. Fool the water into thinking the waterline is longer, it performs well under the current rules, it allows a shorter waterline. None of this stuff makes boats faster, it makes the rules think it's slower, we should have moved on from this shit. 2 Quote Link to post Share on other sites
Miffy 2,144 Posted March 24, 2019 Share Posted March 24, 2019 Distorted hull is to maximize waterline at specific heel angles without compromising light air performance with large amount of wetted area. The idea, whether Verdier, Lombard or even in the 6.5 scene like Pogo 3 or Raison - is pretty much the same. Maximize righting moment with given displacement and keel depth, maximize bow volume at all heel angles without reducing effective waterline. The French architects will concede that upwind it'd make a less comfortable boat, but the idea is to maintain the power and avert bowpitch poling - while also maintaining a plane downwind/power reach so the waterline doesn't limit the small boat performance. IRC theoretically keeps boats safe without becoming unseaworthy because the methodology isn't officially public tho designers can submit proposals for guidance. I'm certainly not seeing any peculiar like the old days and the dominant boats like JPK or Sunfasts don't seem to be unseaworthy grand prix boats. 1 Quote Link to post Share on other sites

Alcatraz5768 415 Posted March 26, 2019 Share Posted March 26, 2019 I'm not saying these boats look like ior boats, I'm saying we're heading down the same track. There's no way this thing will plane or that it will be faster than a boat with a nice fair hull form, but it will do better under the rule. That's my point, designing to ruleslike these culminates in boats that are slower, but rate even slower. If this shape was so good tp52s would look like it, and do away with their silly bulb keels. 1 Quote Link to post Share on other sites

So all those twists and bends slow it down, just not as much as the rule would think: A closer look at the underwater sections of the hull show that we have kept significant rake in the hull, after all these calculations were completed, which for us was a real aligning of the stars. This has kept the water line fairly short, versus the overall hull length. When combined with the high hull volume, this has hit a sweet spot under many rating rules, and is beneficial to performance overall Quote Link to post Share on other sites

JL92S 426 Posted March 27, 2019 Share Posted March 27, 2019 for those of you who are not liking the 3300 hull shape and irc rule’ness might I recommend the Figaro 3? Quote Link to post Share on other sites
huey 2 986 Posted March 27, 2019 Share Posted March 27, 2019 or the Ofcet 32 Quote Link to post Share on other sites
Alcatraz5768 415 Posted March 27, 2019 Share Posted March 27, 2019 The offset thingy looks irc inspired as well, why would it have that keel outerwise. Quote Link to post Share on other sites
Miffy 2,144 Posted March 27, 2019 Share Posted March 27, 2019 If IRC isn't your thing - there are plenty of other lightweight no rating consideration boats out there. If you want Ofcet will gladly install a cast iron bulb instead of the lead fin, or even a lifting keel like ones used on Jeanneau 349s, Pogos, RMs, Djangos/Maree Haute. Like all things, boats are compromises. Not everything has to be designed to fit one customer requirement. Quote Link to post Share on other sites
Flaming 67 Posted March 27, 2019 Share Posted March 27, 2019 Surely the point of the hull form of boats like the Sunfast, the JPKs, the Ofcet etc is that a good proportion of their righting moment comes from the hull form. As such, unless you go for a massive long canting keel, the benefits of having a bulb keel are reduced compared to a narrower boat without a chine. Certainly even the shorthanded offshore guys are mostly using the IRC keel on the JPKs. Giving up a bit of CoG for less wetted surface area, an easier boat to drive (and hence easier on the autohelm) and potentially actually faster downwind. I'm not actually sure if the JPK1080 is even available with the bulb keel that the 1010 was initially. 2 Quote Link to post Share on other sites
Miffy 2,144 Posted March 27, 2019 Share Posted March 27, 2019 Wouldn't have to worry about picking up shit around the keel as well. Quote Link to post Share on other sites

I'm not actually sure if the JPK1080 is even available with the bulb keel that the 1010 was initially. The JPK actually uses a fabricated fin keel that is a strut with hollow fairing at the top and lead at the bottom giving you the benefit of a lower cog but with the hydrodynamic benefits of the straight fin. Currently this incurs a penalty under IRC but from what I hear that penalty may be scrapped for 2020. 1 Quote Link to post Share on other sites

I'm not actually sure if the JPK1080 is even available with the bulb keel that the 1010 was initially. For the most part JPK will build you whatever boat you want but you're right, bulb isn't even an option on the 1080. You had me curious so I looked and you are indeed 100% correct!. It's listed as an option for the 1010 but not the 1080. I've never sailed a 1010 but the 1080 is a very solid and stiff boat, B/D ratio of about 45% and lots of form stability also. I was somewhat skeptical about not having a bulb keel but in retrospect it's completely unnecessary and the fin keel in theory should provide a little more speed downwind. It will be interesting to see if these type of fin keel designs remain isolated to specific boat types or if they become more mainstream in the future. Could what's old become new again? At the end of each JPK model there is an option list: http://www.jpk.fr/?mode=gamme_voiliers_jpk or translated to English for those of us with less than stellar French: https://translate.google.com/translate?hl=en&sl=fr&u=http://www.jpk.fr/&prev=search Quote Link to post Share on other sites
Alcatraz5768 415 Posted March 28, 2019 Share Posted March 28, 2019 The only reason these keels exist is because irc has a penalty for a proper bulb and fin t keel. If everyone in your area races irc then all these boats are a good option, but don't try to tell me they're the fastest thing out there. Quote Link to post Share on other sites
JL92S 426 Posted March 28, 2019 Share Posted March 28, 2019 For our 3600 we would have picked the flat keel regardless, currently we race 2 handed offshore but if we decide to race across the Atlantic i’d rather have the keel that performs best downwind. Or if we decide to take it W/L racing with a crew i’d rather have the keel that offers better upwind performance sub 18kts and better downwind performance all round. There are boats this keel doesn’t suit, we also race a J88, you’d have to make the draft that much deeper than standard to make up for that boats lack of form stability that it would probably push the rating up.

With the qualification that I'm not a naval architect, just someone who takes an interest... To me that looks at the keel in isolation when you should be looking at the whole hull and keel together. With the older IRC typeform, the Corbys, Mills etc that were pretty narrow on the waterline without a lot of form stability then a big bulb on a fin was obviously the way to go and still is. Nobody is putting new slab keels on those boats. When you add in a load of form stability, and you're not in the game of saving every last kilo like a sportsboat or IMOCA etc, then suddenly a reduction in drag looks like a good gain for a small loss in righting moment. Especially if the boat ends up actually faster in the light and downwind as a result. Quote Link to post Share on other sites
Frogman56 122 Posted March 28, 2019 Share Posted March 28, 2019 Guys, the irc rule has no credit for bad design. So probably the NA, miffy and flaming get the choclates? Lets see! Quote Link to post Share on other sites
shaggybaxter 2,718 Posted March 28, 2019 Share Posted March 28, 2019 I’m over buying boats that kowtow to the latest rule. As Alcatraz mentioned, building slow boats that rate slower is not for all of us. And I don’t miss IRC one bit. 2 Quote Link to post Share on other sites
Andrew Buckland 1 Posted March 29, 2019 Share Posted March 29, 2019 Maybe the only 'rule obedience here is no bulb. If you look closely at the light air pics, no transom drag, in fact respectable clearance at maybe 6 knots B.s. And hard downhill, the aft hollow reduces drag...by less extreme bow up. If anyone can explain the cl bow hollow, please do so. But we can bet the heeled bow waterline is dead straight? Quote Link to post Share on other sites
