If not, build 5. 5th is the gin pole and a spare?

  Nice use of materials, pieces, and budget!

  Though since I'm personally sold on a lifting mast instead of a gin pole, I'm not sure it would work for me.

If we assume two piece masts, could they be 4 clones? Like do they HAVE to be top/bottom?

  I think they might have to be top and bottom.  There's much more stress at the bottom, so it needs to be thicker/wider/heavier.  But we don't want the extra weight up high:

    - It's extra weight and cost
    - It adds to heeling moment
    - It helps to have thinner/flexible tops to bend in gusts


  Another limiting factor is what we can actually fit into the leeward hull and then remove.  A 25' half mast would probably need to be fastened outside the hull.

  That said, even the three-part lifting mast in 8'-6" sections might not go in and out of the hatches on the leeward hull as they're currently positioned. 

  But I'm reasonably confident something of that length could be feasible.

Hey Mike;

If you are trailering, don't you need two piece masts?

And, I think, robs carbon masts are about as cheap as you can get?

If not, build 5. 5th is the gin pole and a spare?
