    Sunfish Mast and Boom Specs

    Thanks again Roller. I would like to test hardness of any good spars in order to realize about alloy type. But here in Argentina there is no sunfish boats. I have 35 years of experience in heat treatmets and before getting involved in spars matter I had believed that better alloy meant better...

    Sunfish Mast and Boom Specs

    Thanks Roller. We manufacture dollies for dinghies and laser practice spars with this alloy and we are analizing to begin with sunfish class. But I believe to remember that in any place I read that the mast goes with 6061T6 but the booms in 6063T6 or 5. I would like to use the right alloy and we...

    Do spars deteriorate?

    We manufacture training spars and dollies and our sales policy is train with ours and race with authorized ones. This makes it cheaper for young sailors to start sailing and for professionals and recreational ones. I do not know if Primex closed by bankruptcy or by the change of the class policy.

    Do spars deteriorate?

    We do not manufacture illegal spares. Only ones to practice, unauthorized to race official championships. Official spars should be metal stamp. It happens that often the " legal spars as you say" often are not well done.

    Do spars deteriorate?

    I don't know why someone would like to remove our sticker. If the authentic spars are well done, practice spars can be the same, not better. We want to asure the quality only for our customers with lower costs.

    Do spars deteriorate?

    Since JOTAG is a trademark in the USA from the beggining of this year, we identify our products with a sticker. They are sold by Intensity Sails and West Marine. They were approved for the class just a month before Primex in Chile closed. After that, we were not interested in trying it again...

    Do spars deteriorate?

    Glad to talk with a colleague. I am also engineer and GGM laser sailor. I own a commercial heat treatment and manufacture laser and opti practice spars. You are right. Because the laser spars are made with 6061 alloy, with a well done T6 you get a hardness greater than 16HW and you can be sure...

    Do spars deteriorate?

    Aluminium heat treating consists in three phases: solutionizing, quenching and artificial ageing. Because it changes properties with time. Aluminium alloys do not allow to control hardness like the steel. If chemical composition is right, then laser spars are well made or not depending on heat...

    Laser upper mast

    Our sales policy is: sailors train months and race just a couple of days. So, train with ours that are the same and cost only a half, saving the other for racing. You will save a lot of money.

    Laser upper mast

    We manufacture and sell in USA practice aluminium masts and now we made a composite one but to obtain the same stiffness, wall thickness has to be a little greater. I have never seen a new one with no posibilitiy to get one in the near future because I live in Argentina. That is why I am...

    Mast rivet size

    In order to be sure, you should check carefully if you riveted correctly. If the rivet fails top mast will drop inside the lower.
