I am considering the purchase of a Seacycle (a pedal catamaran found at sea-cycle.com) . I have owned a Seaward kayak in the past and enjoyed it. Now I spend the summer months on the north coast of Vancouver Island, British Columbia and tempted with a kayak purchase again. However, I've discovered the Seacycle and would like to get input on whether the advantages over a double kayak out weigh the disadvantages. I'm in a peculiar situation where the wife wants to be included so a double is needed but she often does NOT want to paddle putting me in a double alone. The Seacycle can easily be setup for one or two peddlers. A Seacycle is polyethylene and costs about the same as a fiberglass double. First the disadvantages to the Seacycle: the drive mechanism is mechanical (chain, gears, bearings, etc.) so more maintenance and possibility of mechanical breakdown, far deeper draft, greater wind resistance, heavy (pontoons weigh 41 lbs each and total weight is 175 lbs), must be transported in pieces (although assembly is without tools and takes about 15 minutes). Advantages: very stable, can move around (legs not locked inside a kayak), easily converted for one or two, cruise at 10 mph, plenty of room for camping gear (although any gear adds wind resistance), handles can be added to drive mechanism making it a whole body exercise, can easily pedal and video or photograph at the same time. I see the biggest disadvantage being the drive unit (mechanical mechanism) and perhaps the polyethylene construction. Any comments would be appreciated.
