: Past poster (many years past) while building a S&G Artic Tern and long time
: lurker. Most assuredly a beginner but ready to build another kayak after
: getting back to a settled place with time etc. I'm hooked on trying one of
: Mr. Yost's designs and have picked the Sea Tour 15 EXP but have a couple
: of questions...First, I have a piece of FREE mahogany that is almost 17'
: and 14.5" wide and CLEAR. It is a full one inch thick and since the
: price is right seems like the right board to use to cut my stringers,
: gunwales etc. - I know it will be heavy but since the price is right
: thought it would be worth it -especially for my first one! Thoughts? Also,
: does anyone have the Sea Tour 15 EXP offsets converted to either
: millimeters or to fractions? I plan to draw right onto my 1/2"
: plywood but am sure I can't be anywhere near precise enough in decimal
: feet or centimeters with my ruler :-). Ohh - i plan to use the kayak for
: fishing and exploring protected waters - maybe some ocean kayaking too
: when not too rough. I'm a little over 6' and weigh 215lb. since my board
: is almost 17' should i maybe go for the 17EXP and could I just build it a
: little bit shorter? Thanks for any responses and I look forward to being
: more active in this community.

The offsets are simple, just went and looked, just multiply each by 12 and you've then got them in inches.

Even easier in metric, already in centimeters, just more the decimal point to the right one spot and instantly you've got millimeters.

Mahogany depends entirely on which mahogany it is. African will be wildly heavy and difficult to work, honduras will be maybe a little heavier than pine and philipean (which is actually a cedar) will be somewhat lighter than pine.
