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)

Time schedule
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
Questions
To do
10 General arrangement
40 Construction
- frames will be all plate
- bulb profiles change into FB
Liftkeel
- detailing might be done by Frans Brandjes
50 Outfitting
60 Systems
General
- overboards - all above WL
- overboards - combine as much as possible
- valves - reduce number of valves where possible
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?
Bilge
- manifold in galley (against trunk ER?), all manual valves well accessible
Fresh water
- reduce number of valves
- toilets possibly come with double connections for FW/seawater, no valve required (possible supplier is Raritan or Tecma)
- hydrofor - to be removable: valves before and aft
Sea water
- galley - own faucet, no connection to FW faucet
Black water
- breather aft in transom, forward in mast?
Fuel
- pump does not require electric valves fore and aft
Electric
- generator - Northern Lights? Wisperpower company is running into troubles?
Propulsion
- Steyr 4 or 6 cylinder
- check out if 26" prop can be combined with Twindisc gearbox, because of space issue, ER trunk might require modification, together with interior engine/shaft angles can be modified, keep 30% tipdistance for propellor, longitudinal position can be modified
- propellor
- Flexofold 26" (optional 25" or 28", pending on engine and gearbox combination, issue is behaviour of sailing reverse)
- drawing of Twindisc is in e-mail of 22-07-2013
