Hi All,
I am after some info and advice regarding displacement hull SUP's.
I have just about finished my latest project, a 20' timber surfski, and am thinking about my next project. A SUP seems perfect.

I have purchased some plans for a CLC Kaholo 14 which look fairly straight forward but I also want to design and build my own (strips rather than ply). I have roughed out a design using KayakFoundary software based on images of the web and need to start fine tuning the dimensions and geometry. This is where I need some guidance. Based on the info below, what sort of board should I be looking at? ie length, beam, thickness, volume.
Any advantages between flat tail, pintail?

info about me is as follows;

95kg, 6'3'. wrong side of 40's.
Strong ocean racing ski paddler. Compete in downwind races occasionally.
Don't surf, have not used a SUP, but have decent balance (lifetime of snow skiing).

Interested in open ocean and downwind paddling. Although I haven't done any yet.

Given that I will have a Kaholo 14, should I consider designing a longer board eg 16ft? Downwind paddling would most likely be in Moreton Bay, short frequency wind waves rather than longer frequency groundswell.

What commercial boards are out there that would suit me and the type of paddling I'm interested in?

Any info, advice, guidance appreciated. I will cobble the design together and post to see what people think.

Cheers, Craig

Well it looks like I will be off the water for another month or so and being inspired by lookielookie and shep I throught I might start building a 14'6" downwinder.

Plan at this stage is to build it in either hollow timber or vac bag timber venneer over foam. I have a soft spot for woodies, or maybe that is a hardspot for woodies

So as I havent even seen a 14 footer I was hoping some of you might be able to help with suggestions on rocker, width, widepoint position, planing nose or displacement. Rail shape, Tail design etc.

Board will be used in WA waters downwinders mainly and some flatwater with 110kgs hopefully standing on it

So I am thinking 14'6" long 29" wide 5" thick with wide point fwd centre by 6", 10" nose 15" to 16" tail and keeping 3. Dont know anything about rocker so what about keeping it flatish in the middle and ~7-8" in nose and 3.5" tail for a planing shape and less if displacment.

Approx estimates on weighst are 16kgs for the Hollow and about 11kgs for the timber veneer. I put something together on aps3600 and post up here for comments.

Thanks
