Inflatable rubber rollers?

[BPhillips]

Anyone know where I can find rollers like in the video below?

I'm building a 66' catamaran and I need to move it a short distance.

those look like sponsons used on portable floating bridges, the military has such devices. You might be able to find some from a military surplus supplier.

might not a wheeled dolly be easier to manage? could be built from scrap parts from cars and trucks. will take some fabrication, but it can be made from available junk.

Hi Bphillips,

these folks produce ship-launch inflatable bags you have seen in the video: http://eversafe-marine.com/products.aspx?cid=5
And in this post you can read some info from a guy from that company: http://www.boatdesign.net/forums/al...r-ship-launch-failure-40153-4.html#post494740
