Unless you're looking for a long, costly (both time and money) adventure, have it professionally transported to the Cape.
If you want a bit of adventure and to save a couple bucks, have it dropped off somewhere along the way. For example, Oswego, NY would be a good place to start from. From here you could join the Erie Canal and enjoy some beautiful scenery and a relaxed trip on your way east to the Hudson.
If time is a problem, consider dropping your boat off in Catskill, NY. This will cut way down on the distance you'll have to travel to the Cape and will certainly help reduce your transportation cost.
If you'll be cruising around Dennisport, you're probably familiar with my old homeport of Sesuit Harbor. Thirty years later, I still miss it.
Enjoy your new boat!!
