There's quite a few.. Bass river, onset bay marina, east nauset marine, etc..
I did a google search with "cape cod marinas racks" and found a bunch.
Looks like it could cost you 12 bucks a foot each time you have it pulled and ready for use, and you pay to put it away I think too. It will run you some money if you use it alot. I also think the hull abrasions and dings will add up over time too.
If you plan on using alot for a week or two it might be less cost to just rent a transient slip or mooring for a couple weeks or a string of weekends. Nice thing about that is your not tied to one area so much. I only have so many days I can get out so sometime I fish in rough water and go for leeward sides or head to the sheltered Narragansett to fish when there's a gale blowing.
