Some fleets have great facilities.
At some venues there are cranes readily available. From pictures I've seen it appears that there are even fleets in which racing T-Birds are virtually dry sailed. In our situation taking a mast down can be a major undertaking, especially for those of us who sail under the T Bird spirit of modest frugality. This does not include finding a place to store the mast while you are working on it, nor the cost of moorage for the boat while this is all going on. It was so bad that we could not raise the main halyard except under no load conditions.
