Under shy spinnaker it bends a litle in 15 knots of breeze when shy but nothing to worry about so have no uppers . That is one of the benefits of the 'D' section , it tapers to round at the top and is stiff in every direction . Not as fast as a wing but much more forgiving and easy to raise because of the light weight . I have no knowledge of the weight of the alloy sections , would be interesting to know . Love your mast tangs , I went the lazy route and used the ss ones - probably spotted you 250gms there !

That is about the double of specified. I'm using the thinner part of the mould, and the chord will thus not be as large as on the 28 ft boat it was designed for, so the ratio might not be far off what it was meant to. The designer of the mast would have me to use the thicker section though, as he said it would give more power off the wind. I think this is big enough though. <br /><br />I don't know what ratio is normal, I think these mast are not considered normal yet, as I have mostly seen them on the large super tris.<br /><br />Jim, your mast is super-light!! Guess you have to pay attention to extra mast head shrouds under spinnaker. How does it handle reefed main?Tor Rabehttps://www.blogger.com/profile/05504285787153280086noreply@blogger.comtag:blogger.com,1999:blog-2925624084410433889.post-29447149130745991162011-02-19T00:57:34.840+01:002011-02-19T00:57:34.840+01:00Hi Tor , wow that is a biiiiig section , you will ...Hi Tor , wow that is a biiiiig section , you will hardly need a sail at all ! My CST 'D' section carbon mast is 40kg all up with all fittings , halyards etc but yours will be much more efficient . Keep up the good work .

It can proberly be turned to a stalling position, not familiar with this kind of mast. It sure will rocket the boat at normal conditions.<br /><br />What is the normal profile ratio between mast and sail (let's say sail at the middle is app 2 meters luff to leech, and this mast is 50 cm gives 1:4). I know you got the mold from a bigger boat.MartinFhttps://www.blogger.com/profile/17996305240765826651noreply@blogger.com
