That is pretty slick looking...must be a larger, swedish form Laker.
What are the basic measurements and expected displacements?
Do you have strong feelings over a single large cockpit vs two smaller ones?
Is it a slight V-bottom, or flat?

It is a hybrid of several design style I have.

She is 19'10 x 30". Mick I know you have concern about getting up around 30" but she will be easy to paddle with the tumblehome panels and trust me.... she's gonna be quick! I need those couple extra inches to get the displacement with kayak performance.

I planned on 2 cockpit configurations: 2 individual and 1 long one. Maybe some different sizes with the individuals.

4" waterline will hold 460 lbs gross.
4.5" : 538
5": 613

Slight v bottom.

Rocker: 2.5" forward and 1.5" aft.

Looks good. How will she work in the open ocean?

It has generous rocker so it should handle waves ok. It's still a long tandem so the skill of both paddlers will be a main factor. The front has a continuous flare so punching over waves should not be an issue.

I might raise the bow height just a bit more but I don't want to go too high so the wind grabs it and turns it into a sail.

I'm inspired again!!!

She seemed to draw up easy. Didn't have to fight with it. So it's getting done next. As with all new designs, it's the assembly instructions that take the longest. :roll:

Slightly higher bow would be a very good thing mate.

Craig, this bottom shape is very similar to a Laker. I have surfed in mine and the difference between this bow shap and a more traditional S&G is remarkable!

The traditional sea kayak bow in all sea kayaks, all of them, tends to make the boat pearl to varying degrees when running down the face of a wave. The bow on these boats works more like a surfboard and the boats are way less likely to broach on the paddler.

The downside is that when punching into waves or chop, they tend to pound a bit when crashing over the wave tops as opposed to parting them like a spear. As in all things kayak, everything is a compromise.

Mick

Here is the link to the Cuda.

Matt is the 30 inch width at the top or bottom,what is the bottom width.
You might think about making a top mounted rudder,it has several advantages,simple mounting ,just a hole threw the top deck into an endpour.,so shape of the stern is no problem. Also by beinng mounted higher you never have water drag on the brackets. I notice most of the K1 are going to this mount.

Thanks Mick. I have been considering building a tandem and this would be easily adapted to a plywood/Cedar Strip Hybrid.
