Contacts

• client: Dick Alewijnse (NL) - DA is contactperson for all questions regarding systems
• project manager: Robin ten Hoope (NL) - RtH also drew up the interior since GDNP did not have time for it
• contact person GDNP: Erik Wassen (NL)

Trivia

• carbon mast costs about 250K which is more expensive than the interior (and the interior is more expensive than the aluminum construction)
• sistership 'Windhunter III' is build by Aluboot (Henk Borneman) and owned by Johan Mast
• ballast system with dumphatches is developed by Heine Deelstra from Gaastmeer Design, in cooperation with K&M Yachtbuilders

60 Systems

• diagrams to be discussed by phone
• ballastsystem Windhunter
  • breather pipe must have sufficient diameter, Windhunter has Ø50 which is considered too small, they advice Ø80
  • breatherpipes go to grills in aftside doghouse
  • when breatherpipes overflow you know the tanks are full
  • Goiot hatches operation lines are lead to the cockpit and have a 2:1 tackle
  • Goiot hatcehs have a lever
  • double bottom is used as cross over, K&M is not satisfied with (hard to make watertight, no inspection possible) and prefers 2 or 3 large diameter pipes
  • Goiot deckhatch rectangular, for example 300x500 or 250x400, plexiglas replaced by aluminum panel
  • advantage of using standard deckhatch is that spareparts like gaskets can be easily found and replaced
  • Windhunter uses only ballastwater, we use a combination with grey water which gives smells so the breather pipe should be a closed ring?
