need info on trimaran with beach cat hull

Charles-

There have been multiple trimarans based on catamaran hulls for the amas. The most common (that I've seen) is the "Tremolino" that uses Hobie 16 hulls. This was a Dick Newick design. I know there was one that used Tornado hulls (called a "Typhoon" maybe??) and we had one here locally that used Inter 20 hulls (I believe Reynolds out of California designed/built that one). Can't remember offhand one using Hobie 18 hulls but it wouldn't surpise me. Might check in Multihull Magazine- Tends more toward the bigger/cruising multihulls-

Hope that helps!

Sounds like you need a DN too so you can sail year 'round!

Here are few interesting one for you to see:

Hi Gary

I was wondering can I use your right up system on a tri?

LOL

http://www.multihullboatbuilder.com/projects/tornadotrimaran/

Anyways, I looked over and the Tremolino seems a bit roomier than the trinado. The Typhoon looks even better. I am thinking about a Typhoon line setup with bended arms like the Tremolino to help in rough sea

I am in the process of reading all of the informations on both trimarans and I am also starting to draw the hull form for the central hull that would look a bit like the Ian Farrier style with a narrow waterline and a wide shoupder on top of it.

My goad would have a daysailor or weekender with that project.

Thank you very much for the links and I will try to update my homepage as soon as I have a few plans of the prototype available.

I am also starting to check with local suppliers for Marine Grade epoxy (like East System epoxy) and some marine plywood for costing

Okay, you sound pretty serious about this! First, get a psychological evaluation (just kidding!)-

Seriously- Check out or subscribe to:

WoodenBoat magazine

Boatbuilder magazine

Lots of info. and company contacts-

I also got a nice video from Devlin (?) Boatworks on boatbuilding (monos but it's something!)-

tremolino website:

why reinvent the wheel? buy plans from newick and build the trem center hull. there are a couple of center hulls alone for sale out there, go to tremolino email list and post an ad there.

good luck!

We're going to try and frankenstein a Coronado 15, and a windspeed 15 into a trimaran with a highlander 21 sailplan (with spinaker)

Yes, we know we're crazy, but we're college students with a serious addiction to insanity.

Charles,

If you're a backyard builder like me, with limited (damned little) control over your workspace environment, I urge you to look into System Three epoxies. I've found them to be far more forgiving of temperature, humidity, and air circulation conditions. and if you order direct, they pick up the shipping.

I wonder, if you're going to have a setup that will enable you to build a hull, why would you use beachcat hulls as the amas? why not just build amas from scratch while you're at it?

It is not the first time that I hear good things about system three epoxie system. I will certainly look into it as far as price and availability.

At this point, I am looking to get a fairly good local for my project. I decided to go back to school in Naval Acthitecture and my school might give me access to a project room.

I am also trying to start a building club to build kayaks, Catamaran hulls and other stuff. I will contact the local suppliers for marine grade plywood and we have a local manufacturer of marine grade epoxy (East System epoxy).

The boat:

I really considered going for the Tremolino setup. The problem is that I feel that you need amas with as much rocker as the main hull and the Tremoline has way too much rocker for my Nacra 5.7 hulls. Also, I think that the boat will not look very good with the "curvy" Tremolino hull and the straight Nacra hulls

At this point, I looked over tons of trimarans for ideas about the setup.

The Trinado and Thyphoon are very nice. I also looked at the TGull and Tremolino. I really liked the setup but again, the rocker of the hull seems incompatible.

I also looked at Warren Multihull Design and Kurt Hugues and other and I decided to make my own plans.

I will be drawing a new hull based on the Nacra Hull but with a new lenght, beam and Draft. I will also be thinking about arc outriggers and a folding system. My boat will be operating in the St Laurence river in cold water and oceasn like conditions: 6-8feet waves are commom in the middle of the seaway. Since the boat will operate in waves and since I really want to steer clear of any capsize, I want a boat rearly squate with really similar looking hulls and amas

Finally, I will be looking at Stitch'n glue for the construction with the proper reinforcements for the stays and the outriggers.

Charles-

There was a Reynolds trimaran here locally for awhile that used Inter 20 hulls as the amas- The main hull design (IMO) would look good w/ the Nacra hulls due to the straight bow design- Might have a look- would have to be "downsized" anyway probably to use the smaller 5.7 hulls-

Hi Kirt

Is this it?

You are right, it is a fine looking boat but I find that the amas are very small compared to many other tris

If it is the case, it is too big for my budget and for my needs. I am looking for a daysailor with reasonable accomodations for camping and an outline more compatible with my current Nacra hulls.

I just finished my semester today and I will start to work on the drawings ASAP. Whatever I choose (like finding a Tremolino hull) I will make complete plans of my central hull.

I might try to contact the Thyphoon and the trinado builders to get a bit more informations.

I would like to start the construction in September so I need a very simple setup because I will have to have the drawings, protopypes and calculations ready for that time.

The other option is to build a Taipan 4.9 but I am still waiting to recieve an answer from Jim Boyer about the plans

Between the two, I am certain that the Trimaran will be much cheaper to build and I will be able to have it in mooring. I just discovered a new catamaran club so if the club is really interesting, I might simply go with the Taipan providing that I can afford it.

So many projects... So little sailing

Charles-

That is it. I thought with the "plumb" bow it would match the Nacra quite nicely and you could simply "scale down" the design to match your hulls/needs.

As for the Taipan- If you visit the F 16HP forum there are at least three Taipan (or Taipan-based F 16HP's) homebuilders that frequent that forum and they can provide you with much information re: costs, etc. I can try to help get you a set of plans if you are interested- They are available (I have a set) and will get sent. Another advantage of building a Taipan is that the class is really getting going and there is now a good market for them here (some folks importing used ones from Aus even!)-
