Priscilla II 320 Posted January 21 Author Share Posted January 21 Happy new year to all yous sea creatures. Just cleared the decks on the ranch of peoples and urgent tasks so now back into the Morby build. Strakes are going on and I had forgotten how much I do hate epoxy and patience is the secret to cutting successfully neat and matching gains in 6mm stock. Quote Link to post Share on other sites

As to strength the sole and garboard will get glassed both sides and the hull strake joints will receive a light cloth backing glassed on the inside. It is one version of many puzzle joints for marine applications ,Russel Brown utilises a variation on his PT II nesting dinghy and I do not see any disadvantages. Scarfing has its place too and Vivier supplies plans that include this method however I am embracing the CNC big model kit thing wholeheartedly and it certainly makes for a very tidy workspace. I suspect the contact area in that puzzle joint would easily match that of an 8:1 scarph and possibly even exceed it. Quote Link to post Share on other sites

There is also a light fibreglass cloth that straddles the puzzle joint on the inside. 1 Quote Link to post Share on other sites
