We move our R29CB somewhere every year. We have a relationship with a shipper in the Seattle area (Cory Gracey of Sharpe Yachts). We have never had a problem of damage in the four-plus years we have used him, but the prices have definitely gone up. He trailers Ranger Tugs a bunch and has the right rig. I think he has trucks going all over the country.
We are having him ship the boat to the confluence of the Columbia and Snake rivers and then pick it up 3 weeks later at the mouth of the Columbia.
Three caveats. First, the odds are high your schedule will need flexibility. No shipper wants an idle truck, so you have to be prepared to adjust your timing. Second, they usually are averse to launching or retrievIng at a salt water boat ramp due to worries about the trailer (we paid extra one year to cover costs of bearing repacking). Finally, check your insurance. There are usually restrictions on coverage if the boat is towed somewhere, and requirements for coverage by the shipper, including proof.
It is not cheap, but time is money. Or in this case, money turns into time on new water.
