Ace you have one more option, get the boat and a bigger car to tow it with But I have a 13ft RIB that works great for two divers, diving pretty close to shore. I went the eco friendly way and got a 4 stroke which weighs the same as the boat so it doesn't go as fast as I hoped but it gets me there. RIB's are pratically unsinkable too just like a whaler because mine is foam filled on top of the tubes.
