Hi, I run an Orkney long liner, same type of craft as yourself, I push it with a 15h Tohatsu, max speed 8knots, but great sea boat, good handling, and like you cheap to run!! I personaly am outside the must go quicker at all costs club (probably my age) in return for a leisurely ride in comfort with no life threatning injuries or bruising !! The Island is an all day trip for me in selected weather as well, but is it not so for everyone? As I see it if the Island is the extent of your desire you are ok, how often will you want to go further? A big consideration for me was running expenses etc, so boat on trailer, and an occasional charter trip when the urge takes me. Derek,V
