Yesterday I helped a new Hobie Tiger owner at our club rig his boat up for the first time. He was missing a few parts and I tossed those to him for free.
He's a new sailor. He's never sailed in his life. But has a nice Tiger now with wings. He took it out yesterday in drifting conditions and got back to shore somehow.
Then I helped him pull his boat up the beach with a flat tire on his cat trax. I informed him that was the last time I'd help until he fixes his trax. Then I explained how to fix them.
