O.K. I've pretty much made my mind up to purchase a sea ray amberjack. Now I need advice.........I'll give you some info on how i plan to use the boat. Scuba diving, little off shore fishing, some over night trips no more than 4 adults. I would aslo like to take the boat over to the bahamas for weekend trips...........Now..I've read until my brain hurts....do i get a single engine boat or dual? i know 2= more maintance but also = a spare incase 1 breaks.....what about fuel economy 1 better than 2 or what??? I know sizes of the engines will make a big differance....I will probably be trailering the boat more than storeing it..... (towing it is not a issue) THANKS FOR ANY HELP
