A Catamaran Question

Having had the privilege of a short sail on a Gunboat a while back, and being amazed at the performance, I am wondering if a 36/40 foot Cat can be built from non carbon fibre materials that can emulate the performance without the price tag.

Re: A Catamaran question.

Sure, but it won't be a cruising boat. There are plenty 18-20 ft cats that can perform better than the Gunboats for WAY less money.

Re: A Catamaran question.

Some Crowther designs are fairly aggressive. You might take a look at those. Buying an existing production design will be way cheaper, fewer headaches, and radically less time than a custom build.

Like fast little beach cats, you want big SA to displacement, long skinny hulls, and light weight.

I think LightSpeed (Atlantic 44) may still be for sale...much less expensive than a Gunboat.

Re: A Catamaran question.

Im thinking of a cruising Cat.

I understand length and fine entry is a help for attaining speed. I need to talk with Minaret and see if a 15 knot average is possible with a 40 footer built out of GRP, in a cruising configuration......

Re: A Catamaran question.

Also some Chris White Atlantic 42-44's on Yachtworld for just under $400K...not cheap, but still radically less than a GunBoat and way fast.

Im not a lover of the Crowther look. GREAT vessel but not my taste.

Re: A Catamaran question.

They are not pretty, but they are fast.

Chris Whites are more asthetically appealing, to my eye at least, and aggressive performers.

No. For the simple reason that averaging 15kts while cruising in a 40' catamaran will break everything on the boat, including your teeth.

BTW, three of us who actually own cruising cats with many years of experience on them (2Hulls owns a fast design and Belizesailor teaches catamaran sailing) have answered. How much experience do you expect Minaret to have with catamarans?

It was more to do with the materials and length versus speed and design criteria. Minaret was very helpful to me previously.

Your comment regarding a 15 knot cruise speed breaking everything on a 40 footer is one of the reasons I am asking regarding length/speed ratio and IF it can be done.

Are you saying then that 55 foot is the minimum for the speed and comfort?

I think GRP and 40 something is doable, but if you want cruising comforts too then that is where the performance reducing compromises will begin. 15 knot average is a really high expectation...that means it must be easily driven into the 20+ knot range. To do that and have cruising comforts then you need more WLL. I used to sail on a Corsair F31 that would do that easily, but definately not a cruising boat.

A 10 knot average would be a more realistic expectation. That still gets you into the 200+ mile a day range....damn good day for any cruising boat costing less than 7 figures.

Lighter more aggressive performance boats can be cantankerous in heavy weather too. Fine if you have a good race crew aboard....not so fine for most cruisers.

Chris Whites are pretty spartan below decks. If their layout suits you then something like that is achievable.

I'm saying that even the Gunboats do not average 15kts cruising. It is simply not a realistic expectation to have for any cruising boat.

I have a friend who races a Mod 70 trimaran. They just sailed it from SF to Ensenada and averaged 18kts. This boat regularly races at 30-40kts.

If you are looking for a boat that can reach 15kts at times, then yes, this is possible. 44CC has one, and so does 2Hulls. A SIG45 may even approach this as a routine speed. If you are looking to do this regularly, and for less than $2million, then that is not realistic.

Besides, you won't catch any fish going that fast.

Some cruising cats can do speed=wind speed, but 15 knots average speed will require 15 knots x 24 hrs wind.

Will PM You with custom 46 ft hull (5 ts empty displacement) ready for completion.
