Everybody wants your knowledge these days
Seriously though, your setup is much better than mine. I just tie my mast to the side deck and run it along the cockpit. Secured on the ends to the cleats, and in the middle to the life line stays.
After doing a few more in the water upgrades I may try to replicate your setup. I do not trailer often though so no rush.
Thanks for all your good info windyway!
