So this morning I decided to set a date for the task, and suddenly thought: "Why not right now?"
The plans recommend laying the Dacron cloth over the hull on a bias, so the material can be more easily stretched around the curves. As I only had about 1" to spare in cloth width this was not an option, so the cloth was run lengthwise along the hull, and held in place with a few spring clamps.
The next step was to bond the material to the gunwale, shrinking it as I went along, starting in the middle and working both ways. What worked best for me was to heat the area from the gunwale up to the first stringer, preventing too many puckers close to the glue joint on the gunwale.
