Hi Mike. I've found that getting the 175mm measurement for the mast to the front eye requires my mast to be almost all the way back with no more adjustment and I can't figure out why.

Great video & tips 👍 Thanks for the information

Thanks

Great videos

Thank you from a newbie to RC sailing Mike. Your series of videos has been very helpful.

Hi Mike, I find the mast rake measurement (and also twist) is highly dependent upon the backstay tension (amongst other things). When first setting up my rig, I set my rake (and subsequently the "initial" twist for the mainsail using the vang) with the backstay only just tensioned such that it is just straight (ie not slack, but not tight and no mast bend) so that I can set the rake and twist at a known repeatable (starting) condition. I then mark up the backstay with a series of graduations for each of which, I measure the associated ('backstay tension on') rake measurement, mainsail twist and mast bend for a given ("inital twist") vang setting. I now have a couple of questions...... 1. Do you follow the same or a similar process to start with or do you have another method for setting a datum backstay tension in order to be able to make your initial rake and twist measurements? & ....... 2. Is your rake measurement of 951mm taken with no backstay tension &/or mast bend or do you tension the backstay to give you 951mm rake for your stated mast gate position with no or a "just" tensioned forestay and take what ever mast bend fore or aft, that may (or may not) give you? Sorry for the rather OCD queries but I believe the mainsail (and jib twist) on these boats to be absolutely critical and am keen to clearly & unambiguously understand how people have initially set up their rigs & controls to give their stated twist measurements before moving on to tweak them to achieve best boat balance for a given set of wind conditions and sea states. Many Thanks
