Greetings.

First - thank you all who contribute here for the depth and breadth of knowledge and experience.

Last year I built my first boat, a Yost Nikumi 19, and have been learning to paddle.

She's 18'4 x 19.75 and 27lbs. Birch ply and cedar, clear 20 mil PVC skin.

I have the skin off for some renovations now, and would like to add a skeg.

I need some advice.

- How large? How wide, how deep, what shape?

- What shape for a cross-section? NACA? (which #?)

- How can I best attach to the frame?

- How to keep the whole thing watertight?

I've considered fixed and pocket styles, and can't make a decision yet.

Most of my paddling is on larger lakes. (Ontario, Simcoe, Skeleton, Fairbanks - Killarney next summer)

Please let me know your thoughts.

Thanks and regards,

- Mike
