Trimaran Kayak

[redreuben]

Hi folks,
I'm interested in a canoe/Kayak trimaran set up like this one,
http://www.clcboats.com/shop/boats/wooden-sailboat-kits/clc-sailrig-kayak-canoe-sailing-rig.html

However I would like the main hull to be more trimaran oriented than canoe or kayak, I would still like to be able to paddle it solo but I would like it to perform at it's best in the trimaran configuration.
My early thought are to use a motor canoe type hull with it's broader transom.

All thoughts, ideas and links appreciated.

Must be heaps of options out there.

Start with this one, sounds exactly like what you described.

And Mik also has outrigger plans.

Jem might have something suitable as well.
-Maybe a Cape Fear http://www.jemwatercraft.com/proddetail.php?prod=CF1531
- or a Sabalo SOT http://www.jemwatercraft.com/Sabalo.php
I know someone with one of these who has outriggers and sail for it: http://www.jemwatercraft.com/forum/viewtopic.php?f=8&t=3426&start=190

Will be interesting to see what you end up with.

Yes I have seen those, can't see why you would think they would stand out as trimaran hull though.

This is what I am looking for roughly, Meade Gougeons Everglades sailing canoe, unfortunately, no plans, professionally built (about 7k !) for main hull alone. Note full bow and broad transom.

compromises & priorities...
A good canoe probably isn't a good tri but would be functional...
A good tri hull is most unlikely to be a functional canoe...
They have different operating speeds, and different force vectors to manage.

big difference between hull shapes.

I'm liking this hull at the moment. http://www.clcboats.com/shop/boats/strip-planked-kayaks/otherstrippers/micro-bootlegger-strip-planked-tandem-kayak-kit.html

With these floats stretched a bit. http://www.teamscarab.com.au/Aussie%203%20m/design.html

But it's only Monday !

Funny thing is I thought of the Microbootlegger the other day because the profile is very similar to the photo in your first post but it doesn't have a transom so I didn't put it forward.

Being a strip build you would probably want stripped outriggers too and most plans for these are stitch/glue as far as I can tell.
You could always design your own outriggers in Kayak Foundry.

Told you it was only Monday !

Check this out ! http://dixdesign.com/Trika_540.htm

Likes; Designed to be a trimaran but can paddle; Long waterlines; Freestanding mast; Has a jib, more string to play with.

Dislikes; Looks a bit fragile for my coast, (but great for the Swan river). Flat bottom, flat panels aren't as stiff as curved and they slam in a chop, which I have plenty off !

However, best thing I've seen yet, What do you think ?

[redreuben]

Aaand,

it has a bigger tougher big brother,

Looks like it would be a good trimaran but probably not a good paddle craft. At that length and beam with a transom design I suspect that the drag would be so high you would rather paddle a bathtub. On the plus side, stability would probably be excellent.

[b.o.a.t.]

I dunno Rob
At 5.6M long, I guessing the transom is probably up around waterline level.
So unless you paddle fast enough to make her squat, there's probably minimal drag.
As a sailing vessel, I like the look & behaviour in the videos.
Almost enough to send off for plans...
Lake Alex & the Gulfs might be a bit of a stretch in any sort of blow though.
A wet ride, albeit exciting.

AJ, yep, agree with that but (there's always a but:U) I'm thinking with that width carried through to the stern and that overall length there must be a large wetted surface area and hence high frictional drag.

I guess if you only want to paddle slowly it doesn't really matter much. My little kayak with the transom rear is slow but stable and I use it more than my other 2 put together.

This guy builds cheap and fast and multiples with improvements all the way.

That's an interesting site, thanks for the link Titch.

Hi,

I am going through the same thought process at present.

Not sure if you've seen the article on CLC's site about the evolution of the sailrig? It provides some thoughts on the best type of kayak/main hull to work with the sailrig/trimaran configuration:

http://www.clcboats.com/life-of-boats-blog/kayak-sail-fun-evolution-of-a-kayak-sailing-rig.html

At present I'm leaning towards the Chesapeake 17, as it's recommended but mainly as I already have the plans :-) I've also considered the Chesapeake Double or Triple, and opening out the cockpit area to be more canoe-like.

Worth emailing CLC and asking JOhn Harris 9the designer) what he recommends for your needs - they're pretty friendly/helpful/responsive each time i've emailed them.

Regards,
Darren

Hi TK1,

Yep been down that path,



Message: Hey Guys, I would like a boat for sedate paddling with a friend, a
boat to give the kids a thrill and a boat to pothole fish and be reckless in
on my own. Also a work of art. My area is expansive estuary (Swan River WA)
and coastal. So an ability to eat miles is mandatory. My thoughts are micro
bootlegger with the trimaran Kit ! Woohoo ! I think of all the boats the
micro has the best front end for a trimaran. My main question is could you
provide some figures to put some rocker in the hull ? Not enough to spoil it
solo but enough to make it tack better with the cat rig ?

Hull shapes optimized for paddling efficiency are always at odds with
sailing performance. As a practical matter there's no way we can
redraw the hull without starting from scratch.

That said, the MicroBootlegger has enough performance to spare that I
think it will make a very good trimaran conversion right out of the
box.

It's not as pretty, but the best subject for a trimaran conversion in
our entire catalog would be the Chesapeake Sport Tandem:
