I just love marinas...
...it seems like half of them won't touch a sailboat with a ten foot pole and the other half shouldn't be allowed to touch one.
Story time.
I was out of time and needed to move my boat 180 miles. I had just done the cutless bearing, repacked the stuffing box, replaced the hose, etc...and have a noticeable ringing sound at low RPM, that is probably shaft related. I had also run out of time to do more routine maintenance. My hired Captain also insisted I have a "professional mechanic" look at it before we left. So I arranged toey to have my fluids and filters changed and the boat test driven by a mechanic at a local marina with a good reputation (expensive, but good I was told) to evaluate any issues with the alignment.
About $650 bucks at $92/hr and I got on board to fine that the engine and transmission had been overfilled and their test drive (2 guys at $92/hr for an hour) was a waste of time.."yep...the mechanic heard the sound too and doesn't know what it is." Our departure was delayed an hour while I siphoned the extra fluids out of the engine and transmission. Very nice people at the marina who helped me out in a pinch, but I still half think I should complain about it and ask for a discount.
End of rant.
The relevant point is...a blind monkey with a rudimentary knowledge of sailboats would know in half a second that the mast on that boat is designed to come down and come down routinely due to its deck mounted tabernacle.
You might try local crane services. I also heartily recommend that you post a question on "ask all sailors" on the main site (sailboatowers.com) listing the location and marina and asking for help and advice. Please note that you need to make arrangements with the transporter regarding responsibilities for securing the mast. They often leave that to the owner and if you won't be there and nobody does it expect to lose a lot of paint off the mast, if it is painted and not padded properly. It is a common shipping issue.
