I tie a permanent small loop in the end of the sheet line (Black) then tie the reefing line to it when getting ready to sail. This makes it easy to reach the reefing line from the seat and cuts down on the number of lines. I keep the sheet line on my right, crossing my thigh, with rest of the line between my knees, on the hatch lid.
(Warning, wordy description follows!
Also, when packing up the hull for travel, I hook the "S" hook of the Bullet Block (part hooked to the sail, when sailing) to the upper plastic Eye (just past the right hand "pocket") then route the end of the sheet line to one of the rear tie-down bungees. It should have just enough line left to hook it over the Eyelet Post by the seat (that the Dagger Board bungee hooks over when sailing). This keeps the sheet line tight and out of the way.
I hope this helps.
