If you're going the Yami it'll have to be the FXHO Cruiser because it's big and wide, which is what you want for offshore stuff. Don't go the supercharger as they use more juice which limits your range. Whatever brand you end up getting, cruise control for long trips, troll mode, height adjustable handle bars, and a neutral position make life easier. Mines a 2012 FXHO Cruiser and I reckon it's hard to beat, though I haven't tried the equivalent SeaDoo.
