you can usually add rope to the ends of the wheels by removing the cover and putting a stopper know on the end of some rope and threading it through the cover whole. The rope makes it much easier to put on and off the boat. if you dont have cradles on the beach wheels it is almost manditory.

I STRONGLY SUGGEST you go to a marine store (or walmart) first and get an anchor and line. wade out to anchor your boat while you return your wheels to your trailor.

you may consider locking your wheels to your trailer with a bike lock to... they are expensive and can ruin your week if they "walk off".

Be sure your main and traveler are sheeted in (no need to whale them tight) but as long as they are in your boat will point into the wind while on anchor.
