Questions

General

Construction

  • portholes - cut-out drawing will be provided by yard
  • Do we put a flat plate under the forecabin escape hatch? NO
  • Do we make hatch in swim platform for removing the stern thruster? NO
  • Curved part with bending on the edge of the roof? YES
  • F23 forepeak bhd - hole without steel hatch? YES

Systems

  • tank connections height
  • Will the discharge of wastewater overboard be made using a pump or a simple gravity discharge ? gravity discharge is not possible because tank is partially below waterline
  • We need 2 drain units(instead of 1, mentioned in purchase list) from Exalto; Allowed ? YES
  • 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 Fuel fill only on one side
  • Do we need to make manual control override for the rudder? - NO, just a square head at rudder shaft
  • Deck fills like in catfish 1 or without the cover Deckfills in sidedecks, fresh water on one side, fuel on the other side, respect distance between deckfills conform CE
  • bow thruster greasing reservoir position(needs to bee DWL+500)
  • as rudder arm, has been chosen Vetus HELM40
  • because the connection kit for diesel fuel tanks chosen (Vetus FTKITB) has filling connection Ø50mm, ventilation Ø16mm, supply line Ø10mm and return line Ø10mm, it needs to replace a few products. In this case, instead of the old ones, we will need:
  • has been chosen also:
    • interconnection kit Vetus FTKITD for the twin diesel fuel tanks.
    • air vent line for diesel fuel tanks Vetus TPC

Electrical

  • Do we habe battery boxes? NO, battery rack of L50x50

Insulation

  • insulation is 80mm wool
  • ER insulation is 30mm from Merford

Interior

  • Do we have a hatch above the engine in the plywood sole? Wat betreft motorluik kan ik zo niet goed beoordelen. Ben deze week niet op kantoor om tekeningen te beoordelen. Is de ruimte krap of niet toegangkelijk? Kom hier anders volgende week op terug.

Paint and Varnish

To do

Naval Architecture

Construction

General construction plan
  • all hatches: indicate brand + type and cutout dimensions
  • indicate gaslocker cutout
  • scuppers - add scupperpipe in aft of sidedeck
  • air intakes ER - specify type (and update sideview in 'shell thickness'

Systems

  • gas line

Interior


Options

  • our delivery must be prepared for the following options:
    • bench at aftdeck - ignore
    • table at aftdeck - ignore
    • cabrio hood - ignore
    • 2 additional batteries of 165 Ah
    • bowthruster 105 kgf - done
    • sternthruster 105 kgf - done

    • LED lighting in stairs - ignore
    • electric windlass - ?
    • combimicrowave with grill - done
    • hood - done
    • radio/cd player with 4 speakers ( 2 interior and 2 exterior)

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 Vetus DT44 - 140hp
  • optional engine is Vetus DT66 - 170hp
  • stern tube - Exalto weld-in type 22.2, OD Ø95 (HIP Ø100) with 3 doubling tubes which can be ignored for building kit

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 - hole 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
