- Deck vs. Keel Stepped Masts | SailNet Community
This somewhat reduces the structural advantages of a keel-stepped mast to next to zero assuming that a deck-stepped mast is properly engineered, and that is a big if! There are several things that I consider critical to engineering a deck stepped mast properly Primary is having a jack post below the mast

The mast will come down on that, resting at a point that is behind the center of gravity On my mast support I put a rubber roller, like those used on boat trailers, on the frame at the point where the mast would come down on it Once the mast was on it, I would disconnect the hinge at the base of the mast and walk it forward
