    Conversion full crew racing yacht to double-handed

    Hi all. My friend bought a 34 ft racing yacht for full crew and we are planning conversion for double-handed.

    Canoe inspiring a racing SUP design?

    researching design for a really efficient flat water sup racing hull. Obviously it's going to be compromised due-to the 14' Length standard. First question comes to mind, what is the minimal Length to Beam ratio needed so wave drag isn't a major factor? Is it realistic given the limitations?

    Curing of the deck bond under vacuum. The collision bow area was laminated at the same time. The collision bow was laminated over a foam core which will dent during large collisions, absorb energy and allow easy repair.
