That works well with Okume plywood, not so much with stiffer ply. In all cases, do not worry if the plywood does not fit perfectly to the...

Re: Narfi's FS17 - Build Thread

The very detailed documentation was a big help in replying to the question about the missing tape layer. Many of my designs take into account a less than perfect fiberglass work and to see good workmanship reassures me about the strength of the boat. Good clean fiberglass work is stronger than a slo...

Re: iguassu falls,Paraná,Brazil SK-14 construction

It reminds me of the testing of the first SK13. It all worked well and was stable enough until the "test pilot" finished that six pack of beer but it was fun.
Thanks for posting the video.
