SeaHaven Pontoon Fingers

The SeaHaven Pontoon Fingers utilise the same high-quality components and designs as used on the SeaHaven Pontoons. Radius end geometry softens the entry to each berth, eliminating harsh corners and, therefore, any risk of damage to the boat. The shoreward end flares toward the junction with the pontoons, strengthening the connection and providing pedestrians with a generously wide lead-in to each finger.

Each float is fully interchangeable and filled with polystyrene. They are of a heavy-duty construction; rotationally moulded to provide the necessary buoyancy whilst remaining resistant to impact damage, frost and long-term decay such as spalling found on concrete floats. Access for repairs and maintenance is simply gained by removing the decking sections from above. Four securing bolts releases each float for exchange or inspection.

As a standard, the pontoon fingers are available in the following sizes:

  • Width: 1m.
  • Length: 6m, 8m, 10m or 12m.

Other sizes can be achieved and special angles can be manufactured to fit individual layouts.

All Pontoon Fingers are joined to pontoons via heavy block and bolt connections. They can be optimally positioned to deliver precise, individual berthing requirements.
