Terrapin's forward tramp failed about 10 days ago. Nearly catastrophic since I went through to my waist! While underway, in good wind. ON AUTOPILOT!
Tragedy narrowly averted!
I built a new one out of vinyl coated poly mesh w shelterite edges. Borders are 1/2" schedule 40 PVC conduit (UV rated). I'm no seamstress, so the stitching lines suggest perhaps I was drinking heavily while cussing at my POS sewing machine. Tie lines are 3mm Dyneema. except along the hull where the fabric bolt rope is bolted to the hulls. The result seems to be up to the task.
All thread is PTFE.
A big job complicated by the fact that the boat remained in the water. My canoe got a work out!
