Do you know if the 31.1 is set up the same as the 41.4 with the traveler raised? Was the project difficult and which lines do you have running aft?
The 31.1 has the mainsheet cleated in front of the wheel, with no traveler. Do you have a raised mid-boom traveler? The C30 in the slip next to me has that, and it's brought back to the cockpit. I could look how it is done.
I'd suggest your question is not really Bristol-specific and you should post it in the gear section.
I have the main halyard brought back. There is a stand up block, another flat block, then a winch to one side of the hatch.
I'm in the process of bringing the boomvang back. That needs pretty much the same hardware I think.
