Now, I can realize that actually sanding is the hardest job during the whole construction. You must admit that the more time you spend sanding the hull perfectly the better result you are going to get. Dudley Dix – the designer – wrote that if you work hard enough in this and the previous periods, you can get as good quality surface as the GRP hulls, but in my opinion if you are working that hard, you CAN reach MUCH MORE BETTER quality and smooth surface even after the first sanding.
This spring I attended on a boat exhibition in Tulln (Austria) as a visitor, and I must confess that most of the GRP boats exposed had worst surface quality than I expected. Furthermore – except the big yachts – hulls of the experimented boats were worse than my own build wooden boat’s in the present state.
So, I have no other things to do but put the next epoxy coats and the top coat(s) (UV resistant) on, and keep fairing until the surface will be perfect.
