I picked up a Seals basic nylon skirt in size 1.4. It fits the 32"x16" (815 mm x 405 mm) coaming OK, but it forces me to sit quite a bit forward of where Tom tells me I should be (easily 6"/15 cm ahead of the back frame) .

What skirt brands and sizes have people used for this size coaming on a folder? I haven't quite sussed out the whole numbering scheme; do any manufacturers have a code for tunnel position relative to the coaming?
