Sailboat Diesel Engine Operation
As noted earlier, diesel engines are sturdy and highly reliable, and operating them today is straightforward.
Latitude and Longitude
The latitude and longitude coordinate system is the key navigational concept for sailing. It is the mariner’s coordinate system.
Propwalk – The Wash Lift effect
The wash-lift effect has been documented heavily by Dave Geer who is one of the worlds leading propeller engineers.
