• Material - aluminum
• CE Category C (required by marina's)
• floating hotel room, will never leave it's berth after mooring
• Hull - as cheap as possbile to produce (combination of smart engineering, material reduction and labor reduction)
• Floating 44 (project 13006):
  • displacement 14 tons
  • floating at DWL
  • trim aft 40mm
  • transverse cross stiffeners removed
  • see dwg P:\Offers\14004 Houseboat\Final draw

Scope

• NA/calculations (total 128h)
  • hydrostatics/weight estimation(interpolation/construction) (40h)
  • intact stability (16h)
  • damaged stability (32h)
  • roof strength (24h)
  • glass thickness (8h)
  • frame strength (8h)
• ME (total 132h)
  • building kit (120h)
  • additional construction details (12h)

Additional

• 7 superstructure frames (5 onder, 2 boven)
• hatch hull
• NO railing
• NO stairs interior
• NO stairs exterior
• NO 'kraaiennest'
• bridge connection
• calculate influence of filled whirlpool on heel

Meeting notes

• 28-Feb by phone:
  • sheetsize 3x2m
  • WT BHD at each side of shell seam/plate at 200mm distance (so the boat will have a double transom)
  • faecalientank will be between the mainhulls so bench does NOT need to be removable
  • hot tub won't penetrate sandwich panel anymore
  • wooden beams on forward part outboard side on longitudinal alu beam, as on inboard side (not with FB to U-profile)
  • U-profile will be bolted so the sandwich panel can be glued down to the beams - create detail for this (FB welded to beam?)
  • standpipe in technical space as in Floating 44 (Ø185, see drawing 'FINAL DRAWING Floating 44)
    • Gielissen will send drawing with indication of space for technical hatch)
  • Monday or latest Tuesday to send an update of the construction drawing (without details)
• 20-Feb by phone:
  • glass at sides to be 8mm tempered monolythic (exterior pane)
  • other glass to be 4-16-4
  • 8 persons to be considered for stability
• Peter will inform if boat needs to be sailing or not for CE approval
• BOA 4980mm for roadtransport (including wooden sideplanking)
• sceptic tank Afmitech Bever Combi Compact
  • contact person Jan Boede de Jong
  • tank W2200 (possibly W2000) to be fitted between hulls, as far aft as possible
  • bench and bathing platform to be removable for this purpose
  • hull fixtures by Navyk
• insulated and heated drain hose for whirlpool Ø80mm
• Dual Docker removable mounting plates by Navyk
• removable cleats by Navyk (see pictures)
• wooden planking
  • Lariks 28mm
  • beams H60mm
• bathing area in front of bench
  • alu grills on alu structure
  • grills tbd by Linskens

hull construction

• bended sheets 3x2m
• on top 21mm wide flanges
• bottom slightly rounded for additional stifness (10mm)
• bow
  • rectangular in planview
  • sloped in sideview
• all tubes rectangular 120x60
• cut out in tubes for draining rainwater from deck
• 70mm distance between platform beams and deck
• NO double transom (Floating 44)
• technical space
  • in SB hull
  • access hatch CO 500x500
  • space position by Niels
• pipe through hull in way of whirlpool for drainpipe?
• bridge connection
• top of wooden planking in line with interior sole

house

• roof of sandwich panel (Kingspan Unidek):
  • faces 12mm chipboard P5 or P7
  • ESP core, thickness as desired
  • wooden ribs (pine), width as desired
  • wooden ribs at 450 COC (can probably be customized too)
  • maximum panel length 8500
  • beams are in longitudinal direction
• side walls
• load for strength calculation to be determined by Linskens

Questions

• aluminum sheet dimension?
• black water tank final dimensions?
• position for technical space?
• through hull pipe dimensions?
• will the U profile on the side be welded or bolted?
• what is the function of the small rectangular profile on top of the swim platform planks?
