Scope

• hydrostatics
• general construction plan
• construcion building kit without
  • bench aftdeck
  • mast
• systems
• possible interior building kit

Time schedule

• wk32 preliminary approval
• planning Linskens:
  • half januar 2012 delivery first boat
  • 1 month for building in systems + interior
  • 1 month for hull construction
  • start hull construction half october

Questions

• thrusters - model and type - standard pipe conform Peter
• gaslocker - position?
• options - what to do with them
• tube railing detail - Udo?
• bathrooms - GRP units?
• steering console - GRP unit?
• Is the ventilation intake ok under the stairs, like in the construction drawing?
• Stern tube outer diameter ∅95 is ok?
• If we move the aft wall forward and if we keep the ventilation under the stairs like in the construction drawing, we'll have to change the bulwark and the windows;
• wheelhouse entrance door details.
• Vetus DC, Fuel Stop; More details needed - solved
• tank connections height
• audio/video?
• Will the discharge of wastewater overboard be made using a pump or a simple gravity discharge ?
• We need 2 drain units(instead of 1, mentioned in purchase list) from Exalto; Allowed ?
• For fuel tanks supply (PS and SB) we need: 1 Splash-Stop Vetus FS5125, 1 Deck entry Osculati 20.667.03 and 1 No smell Vetus NSF25D.

Naval architecture

Tank arrangement

• tanks at CL
• waste water 215l - Vetus BTANK215
• fresh water 450l - Vetus or custom made
• fuel 800l - Vetus or custom made
• waste water tank in 'engine room'
• fresh water tank NOT in 'engine room'
• fresh water tank NOT under beds

Propulsion

• maximum speed 17kmh
• standard engine is 140hp
• optional engine is 200hp (consider for air intake)

Construction

• as simple as possible in order to reduce costs of material and manhours
• use bending parts as much as possible: reduced manhours for welding and painting
• railing aftdeck - mounted on L80x40, flange up and outward, ends in line with aftcabin contour, ends closed with plates (this will be painted in contrasting colour) - see sketch 1
• rubrail swimplatform - rubber D-profile mounted on tube OD30 welded at 6mm distance from shell (spacers not in delivery) - see scan stootrand
• inner transom is a bending part
• transom stairs - 1 bending part
• keel and rudder as Catfish 1, unless we can improve it
• sternthruster model and position as Catfish 1
• air intake - was the Catfish logo but this might give problems with painting so this will become a simple label (needs to allow a flow of 10-15 m³/min for combustion)
• airintake - integrate, solution? (purchase part is about €250)
• bulwark - single plate, tube OD30 on top
• bulwark iwo bow - continue over CL when doubts about strength - add hole for anchor
• forepeak bhd - WT with hatch for inspection anchor arrangement
• chain locker - drains to bowthruster
• chainlocker - no bottom (Forepeak is under the waterline, it will flood)
• rubrail - not present, striping only
• steering console - plywood dashboard panels overlapping steel sides, mounted on FB
• aft deck - soft patch - size as biggest wet unit
• bench aft deck - purchase part
• engine room - as small as possible
• engine room - not in steel

Subframe

Function:

• base for interior construction
• base for systems installation
• mounting of interior + systems into hull

Outfitting

Sole supports

• conform GA, minimum headroom 2.00m net, sloping downward in forecabin
• stairs - riser 225mm maximum
• longitudinal rectangular tubes, in cutouts in frames
• windscreen - coaming as Catfish1
• salon entry - custom purchase part Boomsma

Windows and hatches

• exact dimension and position pending on interior
• drawn is exterior of windowprofile
• profile overlaps steel by 17mm, HIP is offset of 20mm

Systems

• see Excel sheet 'catfish techniek'
• electric switch panel 230V/24V Busch-Jaeger
• optional heating (air) will be implemented in kit

Interior

• finish is HPL except window box which will be Sky
• materials
  • basewood/shell covering - plywood ocoume
  • furniture - MDF + HPL
  • ? - birch plywood
  • Corian soles in wet units
• wet units as Centreboard
• dinette's - rectangular, purchase parts, not to intersect shell
• cabin doors - honeycomb with wooden insert at hinge side + HPL / ABS
• cabinet closing device - push button latch Southco

Surface model

• no extended swimplatfrom
• radius required at corner side/swimplatform to accommodate D-profile (fillet between side and transom, extends to the bottom)
• steering console - steering pump not to collide with joinery wall, move console aft if necessary
• foredeck - no hatches
• bulwark - single plate, continue over bow when doubts about strength
• bollard boxes - extend to deck
• hull to be faired where neccessary
• aftdeck surface - close in way of bench

Building kit

• windows - mark, cut or cut with bridges, up to us
• portholes fore ship - partially cut
• portholes aft ship - cut
• hatches - cut
• salon entry - cut
• thrusters - partially cut in shell
