Something for the multi hull lovers.

I very badly want one of these spaceships

[-]

hypnotoad23@reddit

Plenty of them out there. I’m on number 5 right now

[-]

hypnotoad23@reddit

Upgraded/changed models. One broke while I owned it, but wasn’t anything that I did that caused it.

[-]

NotFishinGarrett@reddit

Oh yeah I know I just have to come to terms with spending more on a boat than my car lol

[-]

hypnotoad23@reddit

You can buy a used 24 for 20isk right now

[-]

NotFishinGarrett@reddit

Yeah Ive seen 27s in the upper 20s as well. That's just a lot of money for a hobby for me right now.

I have an F-27 in oceanside. shoot me a message if you want to go out together some time.

How are these different to sail from a mono-hull?

[-]

StumbleNOLA@reddit

Faster, flatter, much less roll. But you have to keep them light or you can risk the rig.

[-]

StumbleNOLA@reddit

Monohulls bleed off excess power by heeling over, and are limited in speed by their S/L ratio.

But trimarans have MUCH more initial stability. They bleed off excess power by speeding up. With very narrow long hulls they ever a different slenderness regime and have far less resistance even when not planing. But if you overload them they can’t break thru the hump, and have no good way to reduce pressure. This is when rigs come down, or cross arms break.

MASTODON_ROCKS@reddit

Real question, why are trimaran hulls always so rigid? To a layman, one would think you could solve the force issue by adding pivot points to the linkage to allow the central hull to heel a bit

[-]

StumbleNOLA@reddit

As Ivor mentioned below. But also physics… if you allowed the center hull to rotate the windward hull would no longer pull down on the system, and it would reduce the beam on the leeward side as it rotated giving away even more righting moment.

You don’t want a boat to become less stable as the windward hull speed increases.

[-]

IvorTheEngine@reddit

Flexibility would reduce efficiency. It would mean that energy in a puff of wind would be used flexing the structure instead of pushing the boat along.

[-]

EnderDragoon@reddit

I mean... That's what reefing is for. People have put 2 months of provisions on these and sailed across oceans. They can handle weight if the Skipper is mindful of the effects.

[-]

StumbleNOLA@reddit

Yup. I have a friend with a 31 and I own a Sprint 750. Trimarans are fantastic, but you have to treat them differently than a monohull, or even most cruising cats. They don’t have the same load capacity as an equal sized monohull.

Got it thanks!

[-]

IvorTheEngine@reddit

Part of the reason they're fast is because they're light. Monohulls typically have a keel that makes up 40-50% of their total weight, so adding weight has proportionally less effect.

Extra weight always causes more drag but monohulls are often limited by their hull speed. When there's enough wind to reach hull speed, saving weight won't make it go faster. Multihulls are slim enough that their bow wave is small and they don't really have a hull speed limit. Most drag comes from skin friction. Adding weight increases wetted area, and the increase can be quite dramatic when the hulls are so slender.

TheTallGuy0@reddit

You’ve never sailed a beach cat? On multis you trade weight for width, and the power ratio is much much higher. 8’ wide 18’ cat can do 25+ knots downwind with a 400 lb boat and 350 lb crew. Monos can’t touch that

[-]

Arthur-Dent7x6@reddit (OP)

For me the most glaring difference is the sheer acceleration in a puff.

[-]

kdjfsk@reddit

It looks cool, but I cringe at the value proposition for slip rates.

Gotta cost like a catamaran...or worse, but then your getting a monohull cabin...plus maybe some extra hatches that are a pain to access.

[-]

Julesspaceghost@reddit

It's trailerable, but if you did want to put it in a slip, the amas fold in and it would fit in a normal slip. The only issue with leaving them folded in the water is fouling on the sides of the amas.

[-]

MaterialQuantity3527@reddit

I would show up at a boat ramp to launch my F-27 and a local would always ask me how long it took me to launch it. My reply was, “if I do it myself, it takes about an hour, but if I have help, it takes me an hour and a half.”

[-]

MaterialQuantity3527@reddit

Corsair trimarans draw nothing when the daggerboard is up, you can literally beach them. I kept mine on an inside tie; it was useless space for a monohull because of draft. The harbormaster loved it and rented it to me for the same as a conventional slip. I think this is pretty common

[-]

hypnotoad23@reddit

Keep it on the trailer at home, no slip needed

F-boats are the best boats!

Got a buddy who has won the farallon single and dual handed in a 31'. Great boat.

I gave up racing 45 years ago and just cruise, but seriously thinking the new dragonfly 36 would be great. Get to destination in half the time or 2x the miles you can cover.

[-]

icecon@reddit

I was obsessed with the Dragonfly 40 for a bit, but after seeing both the 36 and 40 at the boat show, I'm not convinced the 40 is worth all the extra money.

Neither of them is really going to feel spacious for extended cruising - for that purpose there is the Neel. So the 36 seems "good value" even though it's still expensive.

[-]

brufleth@reddit

I saw a Dragonfly at the Newport boat show. Very nice looking boat. They did a good job with the design. Still kinda cramped, but if you're okay with the space, you can definitely get where you're going very quickly.

[-]

grumpvet87@reddit

i have sailed all my life. owned 5 catamaran. a buddy had a F28R. sooo fun !!! only issue is sleeping on it in heavy air... jogs around in a way that can be a lot less predictable than a mono - not a big deal

[-]

anaaktri@reddit

I’ll take it

[-]

brufleth@reddit

Has a real head. That's deluxe.

MaterialQuantity3527@reddit

I owned a F-27 from 1993 to 2000. Raced it in 6 Newport to Ensenadas. We trailered it to FL for a trip to the Bahamas. We did two trips to Canada, one to the Jervis Inlet, and another to Desolation Sound. This is the ultimate trailerable sailboat. As the kids got bigger, we eventually outgrew it. This is an amazing sailboat; so capable and portable

Love it!

My Ericson 30 Plus' canvas is a dark teal, and looks fab.

That Corsair is a pretty one!
