So, what scenario could be if you choose us to design your houseboat or party boat or another pontoon boat?

We are starting from studying your requirements: usage(1), sailing area, key dimensions (2), crew and passengers or guests, endurance, hulls and bridge-platform materials (3), propulsion (4), etc.

(1) Pontoon boats usage are family houseboats, charter houseboats, ferry boats, sightseeing boats, party / barbecue boats, work boats, fishing boats etc. Non-self-propelled pontoon boats can be used as floating homes, offices, catering establishments, retail outlets etc.
(2) Key dimensions are length, beam, draft, height over water for inland waters, etc.
(3) Floating part of our boats, so called platform-catamaran, could be constructed in aluminum or steel, or combination of both such as hulls made of steel and bridge-platform made of aluminum.
(4) Our boats could be equipped by normal diesel engines as well as hybrid engines, electric motors, outboards, etc.

When our design task is clear for us we offer a straightforward agreement to sign. Generally this agreement repeats articles we talk about here. Apart from design documents which we supply, our design service includes unlimited support during construction via emails.

The design documents which we will prepare are outboard profile, interior outline and arrangement, deck plan, hull structure, platform structure, scantling section, initial weight study, specification, engine and other equipment arrangement.

These could slightly vary and come out as:

(1)  Specification – doc and pdf file
(2)  AutoCAD drawings – 3D models of:

  • Hull and platform
  • Hull and platform construction
  • Hull and platform construction half
  • Hull – engine room
  • Hull – forepeak
  • Hull – frames
  • Hull – fuel tank
  • Hull – rudder, shaft and propeller if inboard engine
  • Hull – skin
  • Hull – skin half
  • Outboard profile
  • Platform
  • Platform and superstructure supports assembled
  • Platform and superstructure supports assembled with walls and windows
  • Roof
  • Upper platform

(3)  AutoCAD drawings – 2D drawings of:

  • Hull frames – construction
  • Hull frames – position and dimensions
  • Layout plan
  • Layout – piping
  • Layout – wiring diagram
  • Engine and other equipment arrangement

(4)  Weight study – excel and pdf file
(5)  Image library in jpeg
(6)  Drawings in pdf

Our job will be done in 2 phases. In phase 1 we will prepare an outboard profile draft showing how the boat appears from the outside and arrangement drawing draft showing the interior layout if any together with preliminary specification and will discuss until a plan suitable to you will arrived at. Then, in phase 2, we will prepare design documents listed above. Phase 2 could be completed in 1-2 month time.

Payment terms are as following. We would like to be paid in 3 installments. The first installment is 30% of the sum contracted and after receiving this initial payment we begin work on the project. After we complete the phase 1, we submit an invoice for the second installment which is also 30%. Upon completion of the project, we email image library and most of drawings in pdf and submit an invoice for the remaining amount of 40%. After receiving the final installment we email AutoCAD drawings and rest of drawings in pdf.

Please contact us by email, phone or Skype to buy stock plans or contract our service.

  1. Hi,
    Could you please give me advice/info on your pontoons please:

    I am about to build my house boat on a tidal mud mooring, the sea floor isn’t level I’d place concrete blocks to level off the mud sea floor to hold the structure level whilst the tide is out.
    Would your pontoons cope with the loading of a home approx. 75 foot x 20 foot when the tide is out?

    Weight of boat would be difficult to calculate as I am a complete dilettante, I’m a first build houseboat virgin.
    Living/dining room, kitchen, 3 bedrooms, 2 bathrooms 1 office and hallway.

    Budget – for the base??
    What about maintenance and longevity in salt water?

    Kind regards
    Tom Gillings
