O'Day 25 Mast
My 25 doesn't have a furler, so I can't help with that part. However, since you have to disconnect the furler anway, you'll probably want to lower it aft.I've rigged a gin pole for mine, but it can be done without one.I would recommend getting LOTS of help with it. The mast gets heavy as it comes down.Because of the fact that the O'Day 25 only has single lower shrouds, you ONLY have to release either the forestay, or the back stay, to lower the mast. Like I said, in your case, you'll probably want to release the forestay. That said, here's the process I went through before I had the gin pole.Unhook the main halyard from the sail. Tie off that end to a cleat on the mast. Do the same with the jib halyard. Your goal here is to have the working end of both halyards forward of the mast, and the aft end made fast.On the working end of whichever halyard is longer, attach another line, this gives you a long angle as the mast lowers. It helps. The shorter halyard should be held by someone (if you have enough people) as a safety. Have someone take the longer halyard as far foward on the hard as possible. Both should be held while the forestay is disconnected.After the forestay is disconnected, remove the forward pin at the base of the mast. Leave the aft pin in place. Have a third person (preferably a third and fourth person) slowly pul the mast aft, while those holding the halyards hold them firm. Those lowering the mast should walk aft as the mast comes down, staying as far aft as they can while still being able to hold the mast. It gets very heavy as it comes down, and they need as much leverage as possible.Once the mast is completely down, remove the aft pin from the foot of the mast, and center the mast on the boat, and tie it down.Just as a side note, When I trailer mine, I use the plastic wrapping plastic that movers use (you can get it at a U-Haul store), and completely wrap the mast and rigging, starting aft and moving forward. MUCH easier than trying to figure out some way to tie the rigging down, and I haven't lost a part to date. Be sure to start aft, or the wind will get under the edges and blow it off.Hope this helps.
