K38BOB you are correct about second tracks however, with the diagonal battens and square top mains you could hoist a trysail up another track but would still have to send someone up the mast to get the rest of the main down by disconnecting the full length batten from the car. Obviously if you didn't you would have two sails up which would negate the effect of a trysail!
The problems with having kevlar, carbon mainsails reefed to the same size as a trysail is that the fabric doesn't have any give and therefore can't take the shock load of inconsistent wind (which is what you have a lot of in storm conditions). Also the mainsail is low down with no gap between the boom and the fabric and large waves will fill the reefed mainsail rememeber a cubic meter of water = 1 ton this effects the vessels stability.
The V70 rule requires trysails but they also had square top mains... Obviously with crew you have more people to deal with getting the sail down but I still wouldn't want to have to deal with it.
Full battens and square top low stretch sails have been on multihulls for some time (before popularized by IACC boats etc). Pull a pin/shackle on the head and lay down the angled batten. Lash it securely. Better of course to remove it.
Good job on the courses!
I don't want to sound sarcastic that is not my intent....
It sounds so easy doesn't it and in theory it is but in practice on a 60 footer on your own.... most likely impossible especially as it is always 2am and dark out :-)
Thank you for the kudos on the courses! It is fun and we will continue to run them if there is a need and people are into learning
