Tweak the system to refine your outhaul.
1. Attach floats to the line fore and aft of the boat, to keep the two legs separated so current doesn’t twist them together under the water. The floats can be attached by any method, but tying a bowline-on-the-bight makes quick work of it.
2. You can also add snaps to the ends of the line to make hook-up quick.
3. For a dinghy or other small boat, you can drive a post in offshore and attach a block to its top. Reeve the line through this block and through another anchored ashore. Tie the dink's painter to the outhaul with a rolling hitch. Voila! Dinghy Outhaul.
4. If you want to move the boat from your "spot" temporarily, for an hours skiing perhaps, tie a buoy or fender to your outhaul line (using that trusty bowline-on-the-bight again) to make it easy to pick up when you return.
