In case you’re interested....
Here are some links to a system I built based on the a Corsair trimaran systems. Mine was an early Mk1, hull #003, with a less refined system, so it’s home made, using spare rigging hardware I had hanging around, and some cables I made with nico press stages.
The mast sections on these boats are heavy and long for the boat length, because these boats have huge sail plans and no backstay. The square top mainsail on my boat is 241 square feet compared to 132 sf on the ODay 25.
I can raise the mast safely in a 20 kt or higher cross wind. As you can see in the video, the gin pole controls the furler on the way down and on the way up.
