Can we name any production 28 foot yachts that can do over 27 knots ?

My NA said that theroretically modern 28 ft monhull yachts could do over 30 knots under sail. Can anyone think of any makes ?

How fast do they sink when they have a big hole and a belly full of water in them?

Hmmm, perhaps I should have said from Sail power :-)

Yeah, I was thinking it would have a couple of tonne of lead dragging it to the bottom.

might be true for a multi-hull, but I have never heard of that for a mono-hull unless perhaps if it is foil equipped?

With a light enough boat, and a big enough wind (like 60 kts or more), it might be possible, but it would not be very controllable is my guess.

I was hoping someone would say that - I asked my NA to send me back some examples, but no reply yet :-)

My reason for asking (as well as giving the NA a hard time) is that he is completing a 28 foot design trailer sailer design for me, much like the MacGregor 26, with a big outboard on it. I am anticipating up to 28 knots with a 90 hp Yamaha 2 stroke, so I thought of using the tag line "fastest 28 foot yacht in the world" as a marketing gimmick.

Cheeky, I know, but I would hate to be passed by a boat under sail alone. The Consumer Affairs Department might get a bit miffed.

28' - 30 kn???

I think a melges E-scow might do it, especially the new ones with masthead asym. chutes. Anyway, they tow water skiers behind them for fun. I think I had mine going about that fast a few times in violent squalls. It wasn't exactly what I would call fun. More like being towed down the tracks by a fast locomotive on while standing on a surfboard. 12 - 15 kn is fairly ordinary, but not for every one.

I think one of the Shaw 6.5s has hit 26kt, and I think some of the bigger ones would be capable of going faster again

Our 26' racing keelboat is capable to reach 18kts, running at 15kts as average speed. I think 30kts is big exaggeration.

I dont know about "those" speeds but here is a "Mini" doing something like 16 to 20 knots - and it is sure is an "exilirating" ride, definately on the wild side and most certainly expert sailors.
Anything above 10 / 12 knots is WAY above "Joe Average" and his little lady so your 28 could end up being a hand full

Manie...

That's no Mini....."Mini's" are 6.5m long, the boat in your video is a Figaro Solo...10.10m long....roughly 33'.....those boys have their hands full!......That looks like it would be fun for about 20 minutes....

30 kn under sail...

I doubt it's going to be fun. Funny maybe but not fun

That size boat with a 90 hp... dunno if it will make it.



If you guys want to talk decent boats, here's how it should be

Hmm, I think its feasible, in flat water. The Macgregor claims 24mph, or 19 knots for a 26ft solid fibreglass hull running a 50 hp outboard.

If I add two feet of hull with a deep forefoot and planing rails, use foam in the topsides for extra lightness, add nearly 50% more HP maybe the fiction can be come reality. :-)

Anyway, testing is a long way off. Something to aim for :-)
