We trucked our GB36 from Alameda, CA to Tacoma, WA where it was offloaded into a yard for some work we wanted done. We then took the boat on its own bottom from Tacoma to Bellingham.
The truck journey took two days, required a pilot car, and in 1998 cost $4,000. The marine trucking company we used, Associated, told us that of the GB line, the GB36 was the largest model that could be trucked in the western US without removing the flying bridge. Back east where bridge clearances can be lower due to an older road system, the flying bridge often has to come off depending on the route.
While the flying bridge did not have to come off, everything else did: mast, boom, bimini, antennas, and venturi panels. Our radar antenna is mounted on the flying bridge face so that made removing the mast a whole lot easier.
My wife and I put everything back on after the boat had been offloaded and blocked in the yard in Tacoma.
