Ward, the block and cam cleat provide an easier way to manage the furling line when sailing short handed, at least on the C310.
Rob, I'll probably understand better when I start sailing my C30. The C30 should be similar to your C310. I keep this idea on my list in case I want to do the same but would probably leave the horn cleat for when leaving the boat several days.
On my O'day 25 everything is within easy reach but the line does run to a ratchet block on
the rear pulpit and back forward to the horn cleat. That gives me a fairlead from center cockpit.
On my O'day's Furlex set up, the line exits the drum on the port side but I can switch which side to run the line aft by adjusting outer line guide.
Can you switch which side the line runs aft on?
The few times we do side dock on the same side as the furling line, I relax it so it droops down below the combing during boarding. Then I re cleat it before leaving the dock.
I confess when I moved to a new slip with starboard side entry mid last season, I didn't move the line. Planned to this spring but I did the next best thing. Bought a boat with the furling line already run on the port side.
Different boat owners will rig their boat the way they want. That’s the beauty of this boating world.
That and sharing those ideas with others.
