The Lineup
One barge.
Built four ways.
Standard Barge
The barge most contractors order. 36,000 lb deckload, flat closed deck, pin-flange connections. Start here, scale to any size.
Learn more →Heavy Duty Crane Barge
10 ft wide, 7 ft high. 58 tons with 1 ft of freeboard per 41′4″ section — available in lengths of two, three and four barge-widths. The 7 ft depth instead of 5 ft gives a significantly stronger platform plus extra freeboard, needed for heavier lifts or when working in surf or choppy water.
Learn more →Back Lake Barge
8 ft wide. Stacks two high on a truck and moves anywhere in Canada without permits. Built for remote and back-country sites.

Priced by the foot. Raked, square or double-raked bow and any paint colour included. Stamped drawings included.

The Sentinel System
Pin-flange.
Two pins make it solid.
Every Sentinel section uses the same pin-flange connection system with a double-head connector pin. Precisely aligned holes give a solid connection after just two pins. Many simple connections spaced close together spread stress across the whole joint so no single pin becomes a critical stress point. Pin every hole before starting a project. Standard, Heavy Duty Crane and Back Lake sections all pin together.
- ▸Two pins make a solid connection
- ▸Pins designed to resist corrosion jamming
- ▸Upper pin heads support a 2×4 flush with the deck
- ▸One system across every model in the lineup
- ▸Double heads make connection and removal quick
- ▸No frozen bolts or damaged bolt hardware at disassembly; pins resist corrosion jamming
- ▸Easy assembly and disassembly make transport quick
