Cradle with wheels?
I know, everyone is going to tell me to get a trailer, and I assume it is a silly question since I can't find anyone else who has done it. However, I have to ask:
Is it possible to bolt/weld axles onto a cradle for moving it around on a concrete pad?
Here's the situation: I sail out of a place that allows keelboats up to a certain weight to be dry-sailed. In order to get to the lift, the boats need to move across a small lot. The issue is that most boats already on trailers are swing keel/centerboard (I'm looking for a fin/full keel), and trailers without boats already on them are hard to find.
So, if a boat only needs to be moved a few meters at a time (from its space to the lift) and never needs to go on the open road, are there any options for rigging up a cradle or something short of a road-worthy trailer?
