Mooring rings and T-bollards are important pontoon accessories for securing boats to floating pontoons, marina pontoons and private boat pontoons.
Most boat pontoons and marina pontoons need mooring rings or T-bollards. Pontoons used only for swimming or bathing may not need them if they do not serve as boat mooring points.
Top Marine offers hot-dip galvanised steel mooring rings for smaller vessels and T-bollards for larger vessels. The right product depends on the pontoon type, surface material, vessel size and required tensile load.
Mooring rings for smaller vessels

Mooring rings secure smaller vessels to floating pontoons. They are suitable for tensile loads between 10 kN and 20 kN.
The correct mooring ring depends on the surface material and structure of the pontoon. On timber-decked floating pontoons, a conventional mooring ring usually passes through the timber beam below the decking. On concrete pontoons, the ring can pass through a side fender or attach to the concrete with a mounting plate and bolts.
Top Marine manufactures mooring rings from hot-dip galvanised steel.
Mooring bollards and T-bollards

Mooring bollards, including T-bollards, secure larger vessels. They are suitable when the required tensile load is 25 kN or more.
Top Marine offers T-bollards in different sizes and strengths. The material options include hot-dip galvanised steel and stainless steel.
On timber pontoons, T-bollards usually fasten to the beam below the decking with screws. On heavy duty pontoons, we usually cast T-bollards into the pontoon during production.
Mooring rings and T-bollards for heavy duty pontoons
When you order a heavy duty pontoon, Top Marine engineers help plan the berth layout and the correct positions of mooring rings or T-bollards. This ensures that the mooring points match the berths and expected loads.
For larger marina projects, the project team should plan the position and strength of mooring equipment together with the pontoon layout, boat sizes, water depth and anchoring system.
