I bought My first boat!!!
All boats are fun. The Sea Dolphin, unless I'm totally wrong, is a member of the Fortune 712/Sea dolphin/Seawind family of boats. Their hulls are pretty much the same - pointy, skinny and fast.
I've sailed the Seawind - it's a jet. I've both sailed and maintained a Fortune - fast, but it's small and maintenance is tough.
Have fun and ask your questions. Find somebody to play with!
