Re: Going up the mast when the boat is in a lift

arf 145 is right. If the yard will allow it, consider another yard, it's a huge liability to them - whether a Travellift, crane, forklift. Going aloft on a 24' boat you'll experience plenty of motion. I'd pull the mast or get a lift up on the crane while boat is in water or ashore.

If she's a 24 footer, it might very well be easier to just drop the stick.

Re: Going up the mast when the boat is in a lift

why not! if the boat is slung properly, boatyard employees do it all the time but i doubt the yard would allow you to do it

re: going aloft on the hard

There's a lot of experienced people on this forum who are pretty emphatic about not going up when the boat is on stands. Do a search on that....

Thinking about it - in the water you've got the keel working for you as a righting moment. On stands, not so much.

I would have thought in the slings wouldn't be so bad, but then have you ever seen the video's of boats falling out of slings?

Re: Going up the mast when the boat is in a lift

Why risk it on such a small boat? You are a significant percentage of the keel weight on a 24 foot boat. And you are a couple dozen feet in the air, versus the few feet of moment arm the keel has.

Brad

Re: Going up the mast when the boat is in a lift

I worked on a 70' race boats management plan... We would never have considered sending someone up the rig on the hard. Not a chance. Boats fall off stands all the time even when everything is done right, but adding a few thousand pounds of torque to the top of the mast while it is blocked of...l no way.

Let's say you are 150lbs, and climb to the top of a 30' rig. That weight aloft can generate up to 4500foot pounds of torque. While the boat is in the water that force can be absorbed by the boat healing over, and allowing the keel to take some of the heeling force.

On the hard the boat can't heel over, which means you are relying completely on the stands to not only hold the weight of the boat, but any heeling force as well. They just aren't designed to do this. If fact I have never seen a yard that supports a boat to prevent it from rolling in the stands. Though if a boat happened to be top heavy enough I guess they might.
