Barrier Coating Bottom; How to work around stands?

I have a 28-foot, 6800# sloop currently blocked on its lead keel and laterally supported by 2 pair of stands and one v-stand on the bow. These were set by the trucker who delivered the boat to my house for refit.

When I had the bottom soda-blasted, they removed and re-set one pair of stands in a slightly different position to expose where the pads had been originally for blasting. Then they removed and re-set the other pair of stands. Their comment was that basically the blocks are taking all the weight, the stands are just for balance and one pair is actually sufficient. And clearly, the boat did not topple over when one pair was loosened and moved.

Now I am applying barrier coat and bottom paint. When done with all exposed areas, I'll want to also move and re-set the two pair of stands to expose the portions covered by their pads now.

Can anyone provide or direct me to a lucid, trusted description of the techniques for setting sailboat stands and jockeying them to expose covered areas? Or should I really buy or borrow a third pair of stands to always keep 2 pair in tension?

Photo is part-way through a PoliGlow application but also shows stands as they are now.

Thanks Hank

You NEED 7 stands to work SAFE

If you losen ONE stand and the boat shows any sign of NOT staying STILL STOP

Wow, I'd be a little nervous working under the boat in that first pic. Not to hijack, but while we're on the subject, is it true that most of the weight can rest on the keel without damaging it? I didn't think keels were made to support a vertical load. Good luck and be safe, friend.

Re: Barrier Coating Bottom; How to work around stands?

Your soda blasters were absolutely right. The keel carries the load and the stands just keep the boat blocked to prevent it falling to the side. If you were to place the full weight of the boat on the side stands the hull could crack because it is relatively thin in those areas.

Get another couple of stands and work around the two pairs that are in place by substituting the spares to make the pad areas accessible. Use normal care in positioning the stands and chains and you'll be fine.

Thanks fry. So what would I do if I ever needed to drydock, I have a retractable swing keel (trailer boat)?

To the OP, get another set of stands. They are cheaper than renting a crane to right your boat after it topples over and lands on your wife's car crushing it and your birthday cake.

Re: Barrier Coating Bottom; How to work around stands?

I've got 4 stands holding our boat in the upright position, a 4x4 at the bow.
I just move one stand at a time just enough to expose the area you want to work on.
Would I like a couple of extra stands, u bet.

Just be carefull!

I'm not happy unless I'm complaining about something.
I'm having a very good day!

Re: Barrier Coating Bottom; How to work around stands?

Just to clarify, the soda blasters simply moved the existing 2 pair of stands, one pair at a time, to expose everything. They did not have an extra pair of stands.

That said, there are enough negative opinions expressed here to give me pause. I would have expected this to be discussed in Chapman's, Casey or Calder but not that I've seen. So would most yards rent me a pair for a week for $20 or $30, with a deposit?

Are you sure about that? They may have removed one of the two stands on a side. Remove both stands on one side at the same time, there's nothing preventing your boat from heeling. This puts a whole new twist on burying the rail.
