Dolphin Sighting on a Road truck cum Boat. Date of experience: March I've done it before and i will do it again. Once in the water it's smooth sailing, but then more bumpy road travel, maybe it would be OK if you were allowed to stand up but No, you cannot. Once underway we were warned that the vehicle has no suspension so it can get a bit bumpy would have been nice if they'd told us that before booking- as my friend has now had a sore back for over a week, and mine hurt on the day of the trip. Thank you so much for you review.
