General

  • 5 pcs built (status 13-Jan-2014)
  • selling price 120-150K (14-01-2014)
  • dislacement 12500 kg
  • COG is forward due to heavy large glass windows
  • classification: CE-C (DMI?)
  • boat might sail on salt water too
  • 2 versions:
    • non sailing (standard)
    • sailing (optional) with outboard engine support
  • aftship:
    • non watertigt space
    • as large as possible
    • space for optional FW tanks and batteries (sailing version)
    • access via hatch in aftdeck
      • hatch is bolted in standard non sailing version
      • hatch is easy removable in optional sailing version
  • watertight hulls to be divided in several compartments (damaged stability)
  • 4 lifting eyes (crane hooks are at corners L5000xB5250)

Competition

  • Cruising home - sold by Gerrit Venema (prins van Oranje), build by SRF
  • Aventura Aquachalet - by Aventura Yachts - torsion issues conform Jan van der Weide

Construction

  • de Sluis Jachtbouw will do the construction
  • for transport hulls + deck must be <3000mm width (hulls are each 1500mm wide)
  • deck will be assembled at Linskens yard (welded connections)
  • superstructure will have a self supporting sandwich sole of 150mm thickness
  • try to get the deck planking in line with top of sandwich sole - deck planking is 28mm
  • deck must have provisions for mounting wooden skirting

feedback Linskens

  • pontoon is very stiff:
    • when the hulls are only supported at the ends, you can remove 1 support without any deformation occuring
    • during lifting of the completed boat not any sounds of cracking
    • during sailing in waves of passing ship not any sounds of cracking
    • too stiff? remove for every next boat 1 stiffener?
  • torsion test (BN03 and BN04?)
    • 2 pontoons, A and B, delivered without vertical diagonal frames and
    • pontoon A with longitudinal diagonals mounted conform drawing
    • pontoon B with longitudinal diagonals mounted in horizontal plane (see pictures)
    • with forklift they lifted one bow of each pontoon:
      • pontoon A they could lift 10-15mm before the other bow started rising, no cracking sounds
      • pontoon B they lifted up to 85mm while the other bow remained in position, they stopped lifting because of alarming cracking sounds
    • next pontoon they will order with longitudinal diagonal cross slightly raised at lower part to increase water clearance

Systems

waste water

  • tank in SB aft compartment
  • waste water pipe through deck (sealed) construction to aftship, no slope required
  • waste water system: Aqualizer
    • supply line Ø25
    • overboard drain hose Ø2.5 above DWL (yard will drill hole)
    • overboard breather hose Ø2.5 above DWL (yard will drill hole)
    • system comes with integrated pump
    • L730xB450xH340 (incl. white e-box)
    • 40 liters
    • 10kg empty weight

bow thruster

  • in PS float only
  • bolted hatch for access
  • thruster Vetus as Catfish 46 (tunnel Ø185)


outboard engine

  • initially Honda 50hp, recommended by supplier Yamaha 60hp (110kg)
  • supplier is Saver boats
  • width between diagonal brackets to be 600 minimum (just make them parallel at CL+500
  • top of bracket to be at DWL+250
  • bottom of bracket to be at DWL-150
  • bolted engine, standard hole pattern
  • clamping thickness 60 (ideal), 70 max, 50 min

Outfitting

  • railing:
    • stanchions FB 50x10
    • upper tube Ø40x5
    • lower tube Ø30x5
    • stanchions bolted on top of U-profile?
