First Post - Our Proa

We're going to build a Proa - our plan is to have it sailing the Chesapeake Bay by 2017.  Here we go...

Why a Proa?  Not all of these features are specific to Proas, but no other design has all of them together:

  • Unstayed wishbone boom masts, 
    • Less to break:
      • no stays
      • no spreaders
      • simpler halyard hardware
      • less stress on sheet(s)
      • no traveler to break
      • no boom vang
    • Safer:
      • no crashing gybes
      • boom safely above head height
      • shunting (more below) can be done as slowly as desired, even used as a moment of rest letting the sails free
      • no getting caught aback
      • mast flex allows for gusts to be absorbed vs. immediately making a pants-staining event with family on board
  • Safety
    • No need to go on the bow to deal with the anchor or foresail issues
    • highly buoyant like other multi's - either hull can keep the boat at the surface
    • unlike cats or tris - potentially self righting - not yet tested
    • foam hull ends to absorb under surface impacts
  • Lower Cost:
    • 1.5 hulls to make, well just shy of 2 ;)  not 3 like a tri, or 2 and pilot house/bridgedeck like a cat. 
    • simpler rigging
    • DIY
  • Time:
    • the less to make combined with a modified open KSS build method which includes the bulkheads and other internal components as part of the mould process should cut down on build time.
    • Less rigging, only 2 sheets for a 2 mast boat.  No travler for the main sail, no jib/genoa/foresail, no spinnaker, no deck rails, no hull penetrations, fewer cleats/ 
  • Comfort:
    • bunks amidships, not at the ends of the hulls 
    • WW protection when desired, or stay on the deck exposed

Why a HarryProa:

  • Weight distribution on windward (WW) hull, vs. water ballast of other traditional Proas
  • Weather protection being on the WW side under cabin or cuddy
  • Cost to build, simplicity reinforced
  • Faster than a mono... I like multis for that reason but don't like the rigging and the complexity in any of them
  • I have no obligation to traditionalism on the water, I am not irreverent for the sake of it, simply untethered to what others consider "normal"

Pics or it didn't happen?  Well nothing has happened yet, other than a lot of dreaming, talking, thinking, drawing and planning.  But here you go: (Credit to Rob Denny)
