My wife and I recently purchased an older hobie 14 turbo. It had not been looked after all that well and so after reading up on specs and how to set up the boat (we are new to this) and replacing tramp we now have a real fun boat to play with. My point is this. The rudders were not set up to original so I set about putting them back the way they are meant to be and the boat is now a pleasuer to sail.
