The SB-285P Sentinel® is Tideland Signal’s large sea buoy companion to the very successful SB-138P Sentinel® buoy. This
buoy meets Tideland’s goal in developing high performance, low maintenance marine aids to navigation. Deployed in over
50 countries, this buoy utilises the latest in materials, manufacturing processes and technology, which provides a rugged,
lightweight buoy with exceptional station keeping and long life, while reducing the long term maintenance expense of floating
aids to navigation.
UV-STABILISED POLYETHYLENE - Rotationally moulded
to form a tough, 12.7mm thick body. Prior to moulding,
colour pigment is blended into polyethylene material
eliminating the need for costly sandblasting and continued
painting. Through a unique mould design and a controlled
process, an increased thickness is formed at major stress
points. This polyethylene material will also repel marine
• DIVIDED INTO THREE SECTIONS - A float section, middle
superstructure section and top section form an abrasion
resistant, shock absorbing buoy able to withstand knocks
and/or collisions. In event of damage, individual sections
can be easily replaced on the deck of a buoy tender, at sea.
• MATCHING OR ALTERNATING SECTIONS - Bifurcation
buoys can be easily made, either red or green as needed.
Cardinal buoys can be assembled using the same method
with yellow and black sections. Fairway or Safe Water
buoys are produced using a process of moulded in colour
graphics, resulting in red and white vertical striping.
• 2.5 METRE DIAMETER FLOAT SECTION – Utilises 316
stainless steel tube ‘skeleton’ to support (4) 1/4 float
sections with 12.7mm thick walls.
