I am probably going to upgrade some of the controls on my 1981 laser to the newer style. Looking on the intensity sails website, I see alot of good stuff but alot of it they say is not class legal. For example, the base for the two blocks that gets mounted to the deck behind the mast. They sell one but claim it is not class legal. Is this really a deal breaker if I am not going to race and win at nationals? Is it something that is really going to be checked if I hit up local races say in the san Francisco Bay area? I am sure I will not be winning any time in the foreseable future. Is it worth me spending the extra $ for this? Next, I was planning on making some sort of out haul, possibly not the stock one but similar. Am I okay as long as I do not have more turns in the line than is in the rules? Next, the boom vang. Again why is one of them legal and the other from intensit not legal as long as there are not more turns than in the rule book? For that matter is it permissable for me to use the stock old setup and invert it so that my jamcleat is on the bottom, which would make it easier to grab? The double cleat on the deck, does that one have to be a specific one also? On that same note, I see that the base for that double cleat is held by two screws, on in front one in back, is that hole pattern the same as the current single jam cleat that came on my boat?
