uff! That is bad news! If you can't fix your mast per GreenLake's suggestions, then you should be able to take the rigging off your present mast and transfer to a new one (Cape Cod). This is assuming, of course, that your mast didn't break due to a rigging failure.. inspect all the parts carefully. Also, some parts are riveted on rather than screwed, so you'll have to drill out the rivets + get yourself a riveting tool to put it on new mast.
Be aware that with any mast, the big cost is going to be the shipping. The mast is 22' long, so it's going to have to go via freight (as opposed to UPS, etc) and will probably be charged a surchage for length. Not to mention packing, depending on the carrier they will want it crated so that they are not liable if something else falls on it. Suffice to say that when I was looking into getting a D&R mast, the shipping cost more than the mast (Massachusetts -> North Carolina). You're in Maine, right? May be worth just driving to Assonet with your trailer, or even the whole boat and ask Rudy for help in rigging. Likewise, there's THIS guy:

Anyway, best of luck!
