I have a need to pull my boat from the water and place it on jack stands for several months while I am doing extended work on the boat. The boat is a 1998 Sundancer.

I have no knowledge of how to go about even finding or buying the stands, how many would be needed and what types, etc. Was hoping someone on the forum could possible educated me a bit.

Thanks

Look under overview/key features for load capacities. https://www.westmarine.com/boat-stands
 
Boat stands.
3 Vee-top keel stands. To evenly support the keel.

Wood blocks are old school and never supported the boat equally.
Rule of thumb is 1 for every 10ft of boat.

Side stands.
4 or 6 to balance the boat upright, all chained together under the hull.

Not sure how tall you’ll need tho.....

Let’s agree to disagree on wood blocking. Being old school doesn’t make it wrong as long as they are properly placed. And improperly placed keel stands can do just as bad, if not worse damage.

The height is determined by the hydraulic transport, or yard, trailer. The stand should not be at its maximum extension, otherwise the boat can rock and shift.

Also don’t forget that the stands should have wood pads under the legs. Small squares of ¾ plywood work fine. This is to protect the pavement, or in the case of unimproved ground prevent the stands from sinking. Stands can sink into soil even where the ground freezes because the stand can warm up under winter sunlight and melt the ground around the legs.

Here’s a pic of our 38 HE:

The wood block that touched the keel, should go length wise along the keel vs just the short section of block. This allows the weight to be more evenly distributed along the keel.

The majority of boat yards I've been to, do not practice this. That's a lot of weight on a small section of keel/wood block.
 
Woods fine, keel stands are better.
All of my club uses them now after 100 years (old club) of using wood.

Keel stands are infinitely adjustable to touch the hull evenly and equally while supporting the hull. You can adjust them all perfect..before letting the weight of the boat come down off the hydraulic trailer.
It’s just not possible with 3 or more wood block stacks to get the same results.
Plywood, shims, 2x4s, various dimensions of blocks..all eliminated.
99% of the time wood is a close-enough-it’ll-do operation.

That’s because it’s not normally possible.
Blocks, ground, boat all on different planes.
“Close is good” .. is all you’ll get with blocks.

Your set up looks ideal. Nice level concrete...beautiful!

The yard I store at makes it happen. Doesn't matter if the boats outside or indoors, all are blocked like that. They do have quite a few smaller boards to use.

But those keel stands look great!
