I must say, the frame details on John Welsfords plans are easy to follow and someone venturing on building the Pathfinder don't need to worry about complex hard to follow sheet sets. His hand writing skills are not great (jokingly) but it's legible and that's all that really matters. I'd rather have the right information handwritten any day over pretty looking incorrect computer text which ruins a $50 sheet of plywood. Accuracy, legibility trumps all.
John has his own forum for folk building from his boat plans. he's always just a click away from answering questions. So even if you were to have problems it's their as a back up. So you not only get his plans, but tech support, fantastic. Thats my plug for his fabulous plans. See links to the side of my blog.
