The mast section on Tanzer 26 is fairly large for a boat its size. The T26 mast is a small telephone pole. I think it would be too heavy for your boat. It would certainly need larger diameter standing rigging and a different mast step. The mast would need to be shortened and the spreaders moved. The weight of the mast would raise the center of gravity on the boat.
Try looking for a mast from a similar sized boat, a Flying Scot, Lightning, for example. You might be able to get way with a mast from J22 or Capri 22 or similar boat.
