i too have considered the trapseat/backrest options, i came into hobie sailing from a cruising/dinghy racing background and want to explore the cruising altrenatives.i am still considering systems including trapseat, pvc outriggers, TheMightyHobie18 style wings and any other ideas, i am open to suggestion. in the meantime i have been racing and trapping out on the wire, i am starting to feel pretty comfortable out there, lots of mobility, sit-down comfort, it gets me on my feet and i am sailing while standing on occasion. if you havent explored the wire option i suggest you spend some time out there before you put all that effort into re inventing the wheel. and if you find a better way please contact me cause i wanna know!
