Here's the one I used for a little while... but nothing beats a full size boat, wheather its a 12' aluminum or a 6' blowup dingy.. This one is modelled after a dozer boat we use here on the Northwest Coast for pulling log booms.. The arm out front was on some of the real ones.. And on mine it's operated off a servo, so you can grab a float stut (or what ever) and pull... No rudder either, It has a cort nozzle so it can manouver in reverse just as good as forward.. The problem I found is if ou have to retrieve a plane that's far out, your depth perseption becomes a little off and it's hard to get the boat to the plane, let alone push it back to you..
