    New F18 - Goodall Design Akurra

    The DS doesn’t require a lighter crew, it just enables the lighter crews to be competitive up the wind range more so than in the past. They have the same edge in light air as always, so effectively across a range of conditions, the lighter crews are going to be more competitive than in the pre-DS era. That is my take. Downwind in medium conditions, where the crew isn’t trapping but you are flying a hull or trying to, the classic sail with more area up high is faster. When it’s over 15kts of breeze though, the DS is drastically quicker upwind and marginally quicker downwind. In very light air both sails are about the same.

    Question is how much was stripped off Defiant to build Patriot, and how much of the electronics/hydraulics left in Defiant are needed to repair Patriot (if that’s’ the call)? I haven’t been following closely so could be off base here-agree that if Defiant is ready to sail, in NZ, and parts aren’t needed, get it on the water! In terms of materials, typically only the highest modulus uni-carbon is tough to get. I suspect they have that in-house and if not, one of the teams does, and if not Hall/Southern have some they can probably spare if not currently using for a rig build. The extent of core damage is a bigger concern.

    High speed foiling mainsail control

    Pretty much mirrors some of the N17 testing done between the overweight aluminum rig and replacement class-legal carbon rigs. If you told me the aluminum mast was 5-7kg heavier I wouldn't be surprised, and the performance difference at this level (arguably the most competitive catamaran in existence at present) was fairly small, possibly immeasurable. The primary reason to stick with the carbon rig is less variance in build, but that comes down to QC on the layup/curing process. Aluminum is much harder to control in that respect, each extrusion is slightly different, with wall thickness on F18 rigs coming out of the same die by the same manufacturer having up to 3mm in variance. HeruSails was built and tested on an A-Cat, it was never as quick as the standard rig. It would be good to know what the advanced wing systems project looks like, with I'm assuming a custom mast? By the sounds of the testing, its pretty much hard wing sail or stick with the existing rig.

    My opinion is the F18 would be an even better boat at 350lbs with c-boards and t-foil rudders. Basically a two man version of a classic A-Cat. Yes, you could go lighter, but it won't be as robust. Yes, you could go full foiling but it won't be as quick on average for amateur teams, and it would be far more dangerous. The two reasons not to do this are cost and class obsolescence. No F18 sailors I speak to wants to sail against less boat, so obsolescence is the greatest reason the boat is frozen in development at this point. As to the DS development, there was pushback in the U.S because, well, its the U.S...historically a lot of F18 sailors have been born out single manufacturer one design classes. They don't like change, and anything that forces them to spend more money. My take is that the DS is faster, looks good, and for experienced crews has given new life to the boat. It has also breathed new life into the class and given a second wind to boats like the C2 that benefit greatly from the reduction in CoE, especially downwind in a blow! The downside is it is more challenging to train very green crews with, it costs a bit more, and in my opinion, has really driven the competitive crew weight to class minimums. It was already mostly there for U.S sailors, but downwind in under 10kts of breeze, sailing at 350 lbs+ is pretty painful with the DS at the top of the fleet.

    I'm sure Fossett was a bit arrogant (earned frankly) and probably a bit cheap like many wealthy people, but if you believe the story here, the French are also at equal blame: https://www.yachtingworld.com/blogs/elaine-bunting/the-strange-story-of-the-jules-verne-trophy-4244 Frankly that gybes with most French experiences I've had, there is a price for native french speakers and a different price for those they consider tourists.

    Nim0s, I think the current F18 rule set is frozen (for the most part, only minor wording edits from here out) for the next 2 years. The trouble with where the class goes from here is any change (lower weight, foils) almost entirely obsoletes the existing class. The only one that might not (at least not overnight) is allowing the use of carbon in the hull while keeping the existing minimum weight, but that would be pretty silly. In terms of builders, I’m still missing your point...there are plenty of builders in the class (more than other box rule catamarans). I suspect most have extra production capacity if demand picked up.

    Pretty far off the mark on what a senior engineer’s salary is. Here in the U.S, mid career/entry level senior engineers start around the $100k Euro mark ($125k USD). True senior level engineers can often be north of $200k/yr. I know plenty on the software side making north of $200k Euro/year, some without formal degrees. I would wager that an experienced naval architect like Verdier is probably making closer to $500k/year, AC campaigns and $600k foils cost what they do for a reason... I’m also reasonably confident some of the TP52 boat captains are pulling in 6 figures, so I would not at all be surprised if the top VG teams had similar salaries for their employees. Finally, I suspect you could back out some of these numbers based on the campaign costs published by some teams (HB’s is pretty well known), an estimate of team size and estimate of boat cost. The latter is a big variable, IIRC, 8million GBP seems about right for a foiling IMOCA, five or take a million or 2.

    Drifter - Free Flying vs. Fixed Luff

    What’s lower stretch than Marlow D12 Max (aka pre-stretched and heat treated Spectra)? Steel, maybe, but then it’s a pain to get the sail back in the bag and a good bit more flying weight.

    Are you sure about that? Latest Quantum Fusion sails with VX skins have very little membrane film and may look pretty close to 3Di.

    I know some boats were built in Australia (2010-2011 C2's for example), other hulls were built at a contract manufacturer. I wonder if Brett has brought the Akurra production back to Australia?

    Yes, basically the hull shape is a Scorpion look-alike. I would have to see them in person to get more details, i.e total hull volume is hard to see in pictures unless other known boats are in the frame. They went to very similar rudder and daggerboard plan forms as well. This is similar to where Nacra went with the Evolution. I certainly think both will be quick (Evolution and Akurra), but its a bit of a wait and see with no races against the top Scorpion teams to date. Personally I am more interested in the construction details, i.e how much additional reinforcement did they manage to put in the Akurra, and where are the boats being produced. Quality control is just as important as the design, and building in a more 1st world country tends to result in a higher quality, longer lasting platform.

    Best use of budget?

    Twin rudder boats tend to have pretty wide asses that are sticky in light air venues. For the O.P, if this is still available (website is dead) I would give it some very serious thought: Its probably the best built of the F-9A’s/most updated. This might be another good option if Redshift has been sold, build overseen by Farrier himself: https://www.yachtworld.com/boats/1996/farrier-f-9a-3707673/

    Umm, class rules prohibit the use of carbon and lifting foils. Plenty of builders as well, you have Exploder (Scorpion), Nacra (Infusion Mk. 3 and Edge), Cirrus (R2), Falcon, Windrush (Edge) and Goodall (C2 and Akurra).
