Thanks to David Welch for providing information on the Helsen 20.

SA above = main + genoa.
Main = 32 sqm / 344.44 sqft
Genoa = 43 sqm / 462.85 sqft
Jib = 36 sqm / 387.5 sqft

Replaced the N39. Same hull as the N37.

LOD: 9.9m / 32.48 ft

Similar to the Maxi 38 but more SA and deeper keel.
LOD: 11.5 m

Similar to the Maxi Mixer.

All timber and plywood version of the Spindrift 37. Slightly wider and larger but with the same mast.
