Apalach,
I have been reading with interest the posts on site KFS and FLYC. You mostly seem to have the head screwed on with RH threads. This is a good place also. I do appreciate Miller monotoring the KFS site and answereing questions and providing some solutions. More manufacturors should do same.
Long and nsrrow with lots of hp got destroyers going 40kts (Italian and Jap). Ours were a bit slower. The nuc carriers go upward of 40kts though with the advent of the steam catapult they can launch some AC at anchor. Th PT boat of WWII fame was a just under 40kt boat with a planing hull and 3 Packart Mustang Engines. Never figured out the hp/weight ratio.
Any way big paddles (foot/leg powered), a long relatively narrow boat means speed w/o the aero downside of hand paddles.
God I'm confused. All this technology. I just want the Adventure.
Thought about the tandum. Realized that wife would only be an occassional companin on the water and if she liked my yak I'll buy her one of her very own.
Note. the FLYC people are padlers not pedalers. Not much room for change there, however they are VERY interested in fishing and that's what it's some about. Different strokes for different folks.
Now, where is the spell checker and I'll get off before the thunder storms lightning strikes my puter.
