20-25 foot lines should be plenty long for some rafting situations, but its always better to be long than short. We have used the same line to go from the rear cleat to the dock(or other boat) and then back to a mid-ship cleat (as a spring line) to maintain better boat position. We normally store each line by making a coil about 8 to 10 inches in diameter, bring the 2 sides of the coil together, then wrap the last 3 to 4 feet of the tag end tightly around the coil, tuck the tag end under the previous loop and pull tight. We put the dock lines, maybe a couple ratchet straps, etc in a small plastic tub that fits under the rear seat between the seat bracket and the doorway to the swim platform. We put a couple boat hooks, a couple shore stakes, and a long handled deck brush in the triangle section of the rear seat support brackets.
If you can find the right color of dock line pre-made, its a lot easier to go that route. The Admiral wanted color coordinated dock lines and we did not see them pre-made, so I got a chance to try splicing a loop in double braided line. Its a lot faster and easier to just buy pre-made lines.
Happy Thanksgiving.
