  Each state is different, and the 12' x 80' limit I mentioned is the highest common denominator from Maine, where I live, to New Jersey, the primary place outside of Maine I'm currently trailering a boat.  I'd rather be sailing in Maine, of course, but I work at a children's day camp in New Jersey each summer, and would like to bring a boat with me that will be comfortable to stay in each weekend.

  I came up with that limit by doing a google search on wide load and department of transportation for each state in which I was interested.

  Corsair has kindly included a list of state DOT sites for wide load permits on their web site at:

  It also mentions FleetOne, which offers a service that will coordinate all your permits for you, for a fee.  They can be found at:

  I hope that helps.  I've not yet found a site that lists everything, or which provides a master limit.

Robert, do you have a link or reference to the Jim Shanahan folding system you mentioned
here? Googling "Jim Shanahan folding system" yields nothing interesting, at least on this

Been thinking along similar lines, although with a Farrier-style link system (properly
referred to as a 4-bar linkage) and sleeve to join the beam halves. Keeping the whole
assembly upright during unfolding might be an interesting challenge, though ;-)

One other question: Mike, where was the source that gave you the absolute unescorted
trailer width requirement in the US? Been looking for that information for a while; have
resorted to corresponding with individual states in the meantime. I also tape-measured a
large bulldozer at a stop here in Colorado once, it was very close to 12 feet wide and
entirely escort-free.

This is a fun problem!
