here is the question i asked a competitor - no response - please help.
as I looked over my dock - I realized the loop was complicated by the rocks forming a crib underneath.
I have included a drawing for you study. My idea would be to bubble from about 9 feet out from shore - note the post at that point. This would give 10" of water in the winter.
The deep end winter depth would be 2' 10".
If we did a loop along the perimeter of the dock from the 9' point on one side to the other it would be about 126'. Instead of going underneath the dock I would simply stay outside and double back the loop on itself - would that work? This would avoid crawling underneath the dock to connect the loop.
