I have a 22, factory pod, so large deck. Have a 4 stroke Suzuki 140 on it and love it. Fast & very fuel efficient.
The Good:
Very light = easily trailerable and easy on the fuel.
Nice layout. Canvas top keeps you in out of the weather when necessary.
Nice cuddy.
Big deck, easily fishable with 3 guys walking around in the back.
The Bad: very light = gets blown around in the wind - especially when the top up.
Where I moor in the summer, there are 2 other Islanders, both with inboards, both a little smaller (20s I think)
One of those has been a dream for the owner, the other has had engine trouble every time I've seen it.
I'm looking at getting a bigger boat. 28'. Will be making a decision next weekend. If I do, my 22' will be up for sale soonafter.
