10 Design

• sales strategy is to offer as much berths as possible for the lowest price so the boat will be very interesting for the rental market
• only developable surfaces
• simple and cheap - the less components the cheaper to build
• furniture to be split in units which can be prefabricated outside the boat (and outside the premises)
• windows
  • sliding window in salon side
  • supplier - cheapest(RAFA?)
• portholes
  • supplier - Gebo
  • PS and SB can be non symmetrical
  • hull - glue plexiglass/lexan?
  • hull - combine with ER air intake?
• deck hatches
  • supplier - Gebo
  • make sure you can reach the hatch for closing/opening
  • entrance hatch - GRP Centerboard standard
• doors
  • transom door - standard Gebo door?
• ventilation
  • very important and permanent
  • all spaces
• sidedeck steps - not IN bathrooms but well before them (possible use for breathers)
• transom stairs
• width 500-550 (older people)
• last step ending under 45 degrees with CL
• transom gas locker PS - for 2x 5kg gas bottle
• swimplatform - length minimum 800mm
• swimplatform - lower part at least 200mm above DWL (to avoid slamming waves against swimplatform
• transom corners - well rounded
• shaping:
  • no forming plates
  • no bending plates
  • only 'radiused' plates
• transom cheeks with knuckles?
• sidedecks - 450mm wide
• superstructure - max width 3100-3150

20 Naval Architecture

Transom rounding

• well rounded to avoid damage during leaving quai side
• keep step of 150mm next to stairs so you can step on the quai side
• hull transom can stop before rounding (shortening hull)

Propulsion

• suggestion Schulz: Craftsman CM4.80 - price for 5 pcs €7700
• Schulz: Deutz 1013M engines are very reliable
• Schulz: replacing 10 propellors per year, sometimes including shaft (under water rocks/stones)

Tanks

• capacity:
  • 500l FW (because of 2 showers)
  • 500l fuel
  • 500l WW (for example in keel, to not create heel/trim)
• tank status to not influence trim/heel
• WW tank above FW tank, transverse in front of engine?
• all custom made PP tanks

40 Construction

• as cheap as possible (simple, light)
• yard budget 600 manhours
• side stiffening - longitudinal T-stringers
• transverse bottom stiffening - CNC frames ending against T-stringers
• roof beams - CNC (profile is hard to make them all exact the same)
• sole on LG rectangular tubes 60x40 (check size), used for cables too (thrusters, windlass)
• salon will be 'removable' in order to bring in the prefabbed interior parts, coupling detail as CC40

50 Outfitting

• fender of rubber or rope
• fender around swimplatform (well rounded corners)
• fender around transom cheeks (renters succeed to damage even this part of the boat with manouvring)
