Hi all,

I am new on this forum. Usually I build bicycles and model aircraft, but now I am contemplating a seakayak.
My current boat is a Wilderness systems Tempest Pro 170, A nice manouverable able rough water boat . On my flat water training paddle I run into the limitations of the hull speed, it just will not go much over 5.5 knot, whatever I do for it. That started me thinking about a S&G boat. Strip planking is to much work.
Some requirements:
-Fast
-Not extremely tippy
-Good secondary stability
-easily rolled
-Footroom for size 12 and up
-Suitable for rough water and surfing on larger waves

Using the lines of the Epic 18 I did some work on a design in Delftship. The design will need a rudder, but that is not drawn.

Some specs:
Design length 5.500 m
Beam over all 0.547 m
Displaced volume 0.135 m3
Beam on waterline 0.499 m
Total length of submerged body 5.442 m
Waterplane area 1.699 m^2
Total beam of submerged body 0.499 m
Waterplane area 1.699 m^2
Block coefficient 0.4604�
Waterplane coefficient 0.6264�
Prismatic coefficient 0.5910�
Waterplane center of floatation 2.653

Here a first picture.

Knowing little about kayak design I would like to have some comments. What information do you need to judge the design?

Greetings,

Merijn
