Is that a B&R rig? You would need a mast that was built for that sail plan unless you plan to change the rig. You'd be pretty lucky to find a salvaged mast that you wouldn't have to ship. You can change the rig but someone would have to do the math (Engineering) for the new rig. You would potentially have different chain plate locations without the swept back spreaders not to mention concerns about rig tensions, deck scantlings and a host of other issues.
What I am thinking is that the cost of a new mast might not be so much worse than the salvaged mast. You would be able to insure and sell the boat.
