Yale and MIT Release Study of Human Sensing Methods

A paper by Thiago Teixeira and Andreas Savvides from Yale and Gershon Dublon of the Massachusetts Institute of Technology surveys methods used to detect the presence of humans. This work could be very useful for those designing virtual propeller guards (propeller guarding technologies based on sensors). The paper, A Survey of Human-Sensing: Methods for Detecting […]

Guard Technologies Category Launched

Prior to mid 2011 we captured technologies with potential applications to virtual propeller guards (sensor based guards) or to conventional boat propeller guards on our Technologies page, now titled Prop Guard Technologies

Boat or Boat Motor Struck Submerged Dredge Pipe: Exemplar Boat Accidents

The Storm Lake Iowa Laass v. Brunswick case has focused attention on boats and marine drives striking submerged or floating dredge pipes / dredge lines. In the Storm Lake accident, a ten year old boy, David Paul McFarlin was killed on May 31, 2010. A 175 HP Mercury outboard struck a submerged dredge pipe, flipped […]

Propeller Warning Labels Seen at the 2012 Tulsa Boat Show
