Theoretical Hull Speeds of Nonsuch Models

Hull speed is an estimated top speed for a boat design, based on the single parameter of waterline length.  A common formula for approximating it is to multiply the square root of that number by 1.34.  The table below provides that calculation for each of the Nonsuch models based on data in the manuals originally provided to owners.

Mast lengths and heights above the waterline

The extrusion lengths (length of the masts themselves, important to know for storage and transport) are as follows:

• N22: 40'-9 1/2"
• N26: 48'-10"
• N30: 53'-3"
• N33: 58'-9"
• N36: 61'-8"

The air drafts (height of the mast above the waterline, excluding any antennae or other fixtures added to them, important to know for safe passage under bridges and wires) are as follows:

• N22: 40'-10 1/2"
• N26: 48'-3"
• N30: 52'-6"
• N33: 58'-9"
• N36: 61'-9"

The above dimensions are taken from the Hinterhoeller Yachts mast layout drawings and from the designer's original sail plans.
