  37. 37. EASY TO DEPLOY (ETD) SURFACE BUOY The Envirtech SB is an easy to deploy “SPAR” buoy “SPAR” characterized by a tall and thin configuration. It floats upright in the water and it has a small water plane and a large mass. This configuration tends to be a stable ocean platform. Adjustment of the water plane area and the mass allows spar buoys to be tuned so they tend to not respond to wave forcing.  Length:  Buoyant diameter:  Focal Plane:  Weigth in air:  Net Buoyancy: www.envirtech.com 12,250mm 1,450mm 3,500mm 1,450 kg + Payload of 200 kg 2,700 kg 37 Southeastern Pacific Tsunami Warning Solutions
