1st time buyer of a Bimini top...vassalating between a 3 bow (6"L/48"H)and 4 bow (8'L/54"H). I'm 68" tall and the floor to gunnel is 24". I'm pretty fair skinned, so can't tolerate the sun very long. Ergo, the Bimini top. Just not sure if I'd be better off with an 8' or 6'. Boat will be used pretty much exclusively by me for fishing...mostly trolling...in Maine on freshwater only. I know this all comes down to personal preference....just thought I'd throw it out there for any recommendations from folks who've faced the same/similar dilemma.
