Yes. Advise the potential buyer to call one or two transportation companies and inquire about the cost and availability of their services. one name I know from personal experience is http://www.brownellsystems.com/
. The buyer may want to start with a company located in NC or CA so he/she may hit on a one-way haul which would significantly lessen the cost.
You might tell the buyer what the hauling/mast removal expenses are at the local yard, but even here, pass ont eh contact info so they can do their own homework - you don't want to be quoted on anything that will become their costs.
Too bad on selling the Cal 33, that's a pretty neat boat.
PS - you will never get a deal out of this unless the buyer thinks you are selling the boat at a price sufficiently below market so you end up covering the transportation cost. The Cal 33 is not a hard-to-find boat.
