We have just bought a B 37 from SNIP, we live in France and they are our local dealer, boat has been delivered to the yard but we are not having it put on the water until Feb 2007 so have no experience of warranty. We are generally very happy with them up to now. They had spotted a small flaw (or damage) on the hull and told us about it and that it would be right even before we went to see the boat. feel free to contactus with any other questions.
