Chemical Container floating boat

boatfloater · Mar 3, 2013

I'm looking at constructing a heavy 2 storey boat on chemical containers or a pontoon system or foam. It would be quite heavy... and could have multiple levels of containers. How much should the floatation part cost? Who would certify it?
Any suggestions?

Certification requirements for a float house are specified by local code regulations.

For example BC Canada suggested regulation includes the following wording:

(c) The flotation system shall be designed according to accepted marine engineering and architectural principles, and shall be approved by a qualified member of the Association of Marine Surveyors or the Professional Engineers Association of British Columbia.

(d) The flotation device shall be durable and not subject to deterioration by water, mechanical damage due to floating debris, electrolytic action, water-borne solvents, organic infestation or physical abuse, to the satisfaction of a marine surveyor or professional engineer.

(e) Where solid flotation devices are not used, an adequate portable bilge pump shall be maintained in proper working order and sounding pipes provided for each compartment. Material and construction to maintain a minimum of 12" of freeboard, and less than two inches of trim and list. Logs, untreated wood and exposed foam is not considered suitable.

(f) The overall buoyancy and stability of the floats and superstructure shall be sufficient (in the opinion of a marine surveyor) to accommodate local wind and water turbulence, moving and launching, wave action, tides, loads imposed by vessels and walkways moored to the structure, and snow loads, or the possibility of water flooding associated with fire fighting.

(g) The flotation system of a floating home shall be designed as an independent unit to work in conjunction with the superstructure and to provide overall stability of the float home.

I had the same idea but dropped it after doing a bit of research i figured it would quicker to build two plywood epoxy pontoons . That way you have two single floats. Much simpler and neater.
