That boat trailer is going to cost you one heck of a lot more than the cost to pay a boat hauler to take your boat to its destination
and then to have your boat lifted off the trailer with a crane. Especially with it being a 34 foot boat. If you do buy the trailer you will either have to rent or purchase
the full sized truck (tractor) to pull it with which means getting a Class A license
as well. I doubt that trailer can lift the weight of a 34 foot boat as well. I think that amount of weight is going to require more than four tires and more than two axles.
I just looked up the displacement
of a Tartan 34-2. It is 10,000 pounds. You will need a truck that can tow 5 tons plus the weight of the trailer. Thats not your typical pickup truck.
What I am saying is paying a boat hauler and then hiring a crane is probably the less expensive and more practical idea.
