Propeller Club Seattle Hosts IMO Secretary General
On Tuesday, September 14, I attended the Seattle Propeller Club luncheon featuring Efthimios Mitropoulos, Secretary General of the IMO. The Secretary General talked about the three main areas the IMO is focusing on right now: 2010, The Year of the Seafarer; The effort to reduce ship emissions; and piracy.

There is a patented device claiming to give between 6 to 10 per cent increased efficiency to the propulsion system applying mainly to planning hulls with inboards. The BOSS (Bolt On Shaft System) as it is called, basically is a tube that encloses the immersed part of the propeller shaft and combines it with a seal and thrust bearing that is mounted directly on to the hull. The self contained unit eliminates through hull sealing and alignment difficulties, and allows the gearbox and engine to be mounted free of thrust considerations. The propeller end of the tube is supported by a P-bracket type of arrangement. For the boat builder, installation times are substantially reduced and the built-in watertight shaft seal ensures a dry bilge. For the user, the reduced losses give the benefits of lower fuel consumption, improved range or a higher top speed. It’s available for shaft diameters of one to four inches (25 – 102mm) and is claimed to lower propulsion noise and vibration.
