I've used my ole stand by 4:1 that has a camcleat...this is the same rig I use to haul my booty to the masthead when it's up. I have no real complaints with power issue however twice now against my better judgment I have lowered the mast while afloat, couldn't have done that w/trailer winch. I do have a 2-speed trailer winch and it still wears me out if I'm forced to pull Chimera up onto the trailer at a low water state or poor ramp.
I just turned down the OD of some 3/4" sch 160 st.stl. pipe to fit the stanchion base. I intend to swing from this point since I know the base to be strong and they're located in line w/mast base. I've seen some swing from the shroud chain plates, but I am looking for more control tha I can get from strap attachment. Plan "A" is to use 3/4-1" EMT for the frame I have to figure out a head configuration for the "A". I want it to be rigid in use but break down fast and store small. This is one of those parts I'll use 1-2 hrs yearly and doesn't have a 2nd use.
