: The f1's stern is sure more critical as it has been designed to
: surf huge waves. So if you really want to add an extra section,
: you probably want to add it in the stern than in the bow.
The stern already has 3 cross sections quite close together to control the tight curves there, but the spacing between some of the front cross sections is greater than the Yost Sea Rider, I think, for example
: P.S.:
: How did you get the right offsets for the F1 cross sections?
Maybe it's not easy to see from the photo link I posted, but I've built wooden forms (multi joint rings) around my existing F1 hull that conform to thehull shape. Once I've added female forms for the bow and stern shape, I'll remove the kayak and then use the rings as female moulds to build my cross sections inside
