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.
