Posts: 242 Brisveagas | 3M do the shark film I think. Not as simple as slapping it on as it has to be made to suit the speed and length of you boat. An expensive exercise. Not sure that it's legal in any dinghy or cat classes either. I know polymer is definitely banned.
You would have to have some serious skills to attempt carbon beams and masts. And when time is factored into the equation the price becomes outrageous.

Posts: 893 | If the forestay remains the same length and one side stay is lengthened with the other shortened wont that reduce the mast rake slightly?
Darryn
yep, if the forestay to bridle connection is above the mast base relative to the platform. if they are at same height then rake will not change. the canting rotation occurs around a line from mast base to bridle (imagine a triangle being rotated about one of it's sides) this is if you measure rake from mast top to rear beam on centreline. Its irrevelent at what height the front stay joins the front bridle, as long as the front stay base remains on the centre line, as soon as there is any rotation of the top point an arc will form however small ( basically the radius of the distance between top point and bottom point looking straight down ), causing the mast rake to change. I personally would favour a change in the rule to allow mast rake, it would on long distance racing help reduce an over powered rig. After all we are a semi develpment class, whats the problem. However from other class's which have gone down this route, around short form racing, the time lost to set up the canted rig far out ways just sailing the boat and keeping in front in clean air. Any way Macca is bored and just raising pedantic points of no real worth to the class to basically wind people up. When Macca designs, builds and races a boat within the class then I think we should start to take more notice of his internet scribblings. Up until that point he is just another interested internet scribe in my view and his views are just that, internet musings. | | | Re: AC tech

Other than that, I agree with your sentiments about macca. Doing a Macca here, altering the front stay bottom position alone will not cant the rig, the side stays length have to be altered or the mast base position ( easiest and most beneficial in our boats ). | | | Re: AC tech

If this is a serious proposal then I'm furiously against it. This goes against everything the F16 was funded upon. Wouter

Posts: 1,021 Australia | Event though I have paid my membership fee, I am still unable to log into the F16 forum thingy, so I can't download the latest and greatest rules. For all I know, the Minimum weight has been changed to 125kg and carbon beams and masts are banned... Dreams are free, my advice is to dream of a very pretty girl and ask her for her telephone number, when she replies and you wake up, try ringing that number. The odds of that same very pretty girl being on the end of the line would be about the same as "the Minimum weight has been changed to 125kg and carbon beams and masts are banned" Wow!!! I just had the most amazing dream!!! The pretty girl answered when I called the number, just like you said! Fantastic stuff Wayne, what other tricks do you do?? Can't wait to see the new class rules | | | Re: AC tech

Other than that, I agree with your sentiments about macca. Doing a Macca here, altering the front stay bottom position alone will not cant the rig, the side stays length have to be altered or the mast base position ( easiest and most beneficial in our boats ). arrrgghhh. my explanation is not enough...looking at the picture it is arranged for two boats, one with a high bridle (as normal for a beach cat) and one with a low bridle (not normal and used for illustrative purposes only). the rakes are shown for the upright positions of the rigs. then beside each of those is the canted rigs (with sidestay adjustment) for high and low bridles. notice that the high bridle decreases rake with cant and the low bridle increases rake with cant. the only way to cant the rig without also changing the rake is for the forestay attachment to be at the same height as the mast step. this is with a fixed length forestay which our class rules require with the rig tension adjustment requirements. mmm...pretty girls on pretty boats...it is my happy place
