Comparative structural analysis of hull forms, keel ballasting configurations, and spar arrangements for offshore cruising vs coastal racing.
Monohulls vs. Multihulls
Monohulls depend on positive righting moments generated by heavy lead or cast-iron ballast keels at high heel angles. Modern catamarans and trimarans depend on broad beam static stability; while offering higher cruising speeds and level sailing, multihulls lack ultimate self-righting capabilities beyond 90 degrees of roll.
Classic Rigging Classifications
- Sloop: Single mast carrying one mainsail and one foresail; the most aerodynamically efficient windward rig.
- Cutter: Single mast positioned further aft, carrying two foresails (staysail and jib); ideal for heavy offshore passage-making.
- Ketch: Two masts with the shorter mizzen mast stepped forward of the rudder post; divides sail area into manageable sizes for shorthanded crews.
- Schooner: Two or more masts where the aft mast is taller than or equal to the forward mast; unmatched reaching power in open ocean swells.
