Make sure the transporter is insured and bonded to cover "your" potential loss, not just their loss! Make certain the value of the vessel is covered 110%. My last experience was very good - shipped on our cradle. You may want to check with your insurance provider to review the shipper's information?
The Real Pros have fantastic Trucks and awesome hydraulic trailers. Estimates for our 272 Oday (5200 Lbs) for a 200 mile shipment were $750 to $1500. We chose a Mid Estimate, but shipper had a problem with prior load, then we chose a low price Quote due to availability and delivery was uneventful! Remember CYA or CYBoat...
