pulley strength

What are the chances my main sail or job pulley at the top of the mast is strong enough to carry my weight to change my mast lights. 230lbs.

Re: pulley strength

Sigh . . .

If your boat looks like this one, the "pulley" at the top of the mast will probably be strong enough.

But if you own a Laser, probably not.

Re: pulley strength

230# is a lot of weight at the top of the stick on a boat that size (2800# total displacement). Who would be cranking you up? I would be concerned about the boat's stability with that much weight that high. What is the general condition of the boat? The blocks may be the least of your problems. How big are the shrouds? What is the condition of the chainplates? For a boat that size, it may be easier/less risk to lower the mast -- you won't have to worry about going splat on the deck and you'll be able to inspect, repair and tend to any other items that need attention. Find a club with a gin pole or rig up an A-frame. Or just find someone who is lighter and that you trust to do the work.

Re: pulley strength

... or maybe you can get access to a mast tower, or a man-lift, or a tall pier. For a boat of that size I wouldn't be real comfortable going up myself.

Have either of you been up a mast ...and then did work at the mast head? Have either of you hoisted someone up a mast? Are you using a bosun chair? Is the boat on land or in the water? Most would recommend against going up the mast if the boat is on the hard.

Your P dimension is 22.5', so a fall would be bad (think 2-story building and a hard unforgiving landing). Do you have an ex-wife? One with rounded corners and no blood (no stains or dings in the gelcoat)? Joking aside, consult someone who knows what they're doing. Drop the stick or find a bridge, tower, bucket truck...

You're new here, and you'll learn that there's lots of free advice given out here -- some of it is good...

pulley strength

I have quite a bit of rock climbing experience. As well as high and low angle rescue (firefighter) so I know all the rigging knots and tackle. We only need to go half way up. The top light is good. The middle light is out. Thanks for the advise!

Re: pulley strength

I agree that the halyard sheaves will probably be strong enough. I would guess that stability (on a calm day) would be OK for only going part way up. If you did tip the boat, you would just get tea-bagged into the water. I trust you have good instincts for safety, with your background.
