Anyone have any experience building a large boat dolly? I have a 17' Spectrum. The dolly will be used to wheel the boat from a rented "garage" 100' to the "elevator" which lowers the boat into the water.

I have 6 1000lb casters. Tomorrow I'll buy some lumber and put something together. I'm thinking 6' long x 6" wide "bunks" that the hull will rest on. I'm still debating what to do between the casters and the bunks.

Any ideas on what sort of structure I should build to support the boat?
