Do you install the M-711LP?
Yes. Wet Tech offers installation services: we can set your M-711LP buoys on station with the anchor block, chain and light. Call 337-893-9992 to schedule.
Is the M-711LP a 700 mm buoy?
It is in the 700 mm class: the M-711LP is 28 inches (about 711 mm) wide and 60 inches tall. If your spec calls for a 700 mm marker buoy, call 337-893-9992 and we will confirm it fits your job or build one to your spec.
What is the M-711LP used for?
Marking pipelines, dredge pipe, spoil banks and channels in shallow water. Good fits include shallow and inland water, marsh, pipeline and hazard marking, and private aids to navigation.
Will it sink if the shell is punctured?
The M-711LP is completely foam-filled with 2 lb closed-cell urethane foam that meets or exceeds United States Coast Guard requirements, so there is no hollow air chamber to flood if the 0.25 inch wall rotomolded polyethylene shell is holed.
How much buoyancy does it have?
Net buoyancy is 120 lb.
Will it stay upright?
Yes. A self-righting counterweight brings the buoy back upright, and the low profile keeps it steady in shallow water.
What lights can I put on it?
The Wet Tech-built M-711LP has a top lantern mount that accepts USCG and IALA compliant lanterns from all major brands. We can supply and fit the lantern for you, or mount the one you specify.
