Off Topic - America's Cup Sailing - Foiled Monohulls

Postby Dave_5280 » Sat Jul 11, 2020 1:31 pm

Off Topic

I'm always amazed at the technology of the sailboats that race in the America's Cup. I read that after the first 150 years of the race the boats were only going 4 knots faster than in 1851, but in the last 10 years they have gone 3 times faster because of foiling.

Now they are going to use single hull or monohull boats that are foiled:

Thank these guys and the Moth class for a lot of the research that’s gone into making our kite foils feasible.

Watch the videos! They nose dive. But seems they recover better than the hydrofoil cats.
I very much hope the race happens

They also have lift offs! Followed by a huge splash and sometimes capsize 🤕🤕🤕.

But are they faster, more maneuverable, better upwind, etc. than the catamarans....???

Watched a regatta a few weeks ago and the cats were doing around 50+ knots. Nose dive at that speed and not recover and .....

The main thing is mounting a campaign with one of these boats isn't a $100+ million dollar proposition. That kept a lot of countries out of the running the first time in SF. It was a little less in the Bahamas, but still out of reach.

I like to watch the Americas cup races. We have it at the moment. Controversy with sour grapes allegations from someone kicked out of the Kiwi team for selling/giving secrets to an opposition team. Less time with ongoing covid 19 and our border control for teams to prep for local conditions but I'm sure a good challenge will still be mounted. We struggle to keep the design talent in NZ because the local economy is so much smaller than that of some of the competing countries.

Most of all though, I wonder about the racing clearances between boat's hydrofoils. The above water clearances are no longer enough between boats.

interesting as a cat is always quicker than a mono hull without a foil, does a foil remove the advantage?
