Ok I think I'm gonna try to hoist myself up tomorrow and take a closer look. The boat came with a harness for doing that. On the S2 8.0 though, the halyard goes through the mast, making it a 2 person job. I was thinking though, I could rig a block to the main halyard, run the harness rope through that block, and raise the block up to the top of the mast and then pull myself up with it. Is that safe/reasonable?
In my business I use either a 6 to 1 block and tackle system, for when I'm working alone and have to haul my own fat ass along with 40 lbs of tool and various parts up the mast, or a 2 to 1 with a ratchet block (at the bottom) for when I have my associate to help me.
Whatever you use, just be careful. Use a second halyard to hold whatever block and tackle system. Even if you have to wrap it around from the other side of the mast.
Never use a snap shackle.
Don't trust a splice that you haven't proven.
Tie a Bowline knot. (If you don't know the bowline, well then there's your next project.
Have someone standing by. Even if it's just to tail the line for you. (That means taking a few turns around a winch or one turn around a horn cleat and keeping the slack out of the line)
You will do fine. Just be methodical and redundant when it comes to safety.
