A propeller converts the rotary output of a boats engine into an accelerated stream of water. This acceleration creates thrust that pushes the boat through the water. To work efficiently, propellers must be properly matched to their engines and transmissions. Other important factors include the boats displacement and waterline length and the clearance between the propeller shaft and the bottom

If you sail on a small boat without electronics, you may appreciate having some basic speed and heading data to help dial in your tactics and sail trim. Velociteks new Speedpuck is a handheld GPS receiver that displays your course and speed over ground and allows you to recordand later downloadthe data so you can compare your performance against other boats. This clever device also displays
If you cant run air conditioning on your boat theres no reason to get overheated. Meet the new Bora 12- and 24-volt fans from Caframo Marine. The three-speed fans, available in either white or black, have a locking cam mount and are easy to install. Best yet, the fans move a lot of air but are quiet, unobtrusive, and lightweight. The compact units can be mounted sideways, upright, or upside
One of the worst onboard messes I ever had to contend with was on a lumpy delivery from Stamford, Connecticut, to Marblehead, Massachusetts, when our engine blew an oil gasket, spray-painting the engine compartment and filling the bilge with petrochemical filth. Oil Dri could be the ideal solution for such nasty predicaments. These hydrophobic, oil-absorbing pads and bilge socks are ideal for
Knowing is believingNobody likes the idea of breaking out the EPIRB, but if calamity strikes and you need the cavalry, wouldnt you want to know that its working correctly? While most EPIRBs have a simple on/off button, ACRs new Gobalfix iPro 406 GPS EPIRB (both Cat I or Cat II units are available) features a small digital screen that not only displays the units GPS

For millennia, sailors have proven they can cross vast oceans on boats big and small. But what if you removed the crew, added two hulls, and fitted a hard wingsail and hydrofoils? Meet the Autonomous Unmanned Surface Vessel (AUSV), developed by Harbor Wing Technologies. It carries no crew, and it gathers the majority of its energy from thin solar films on its wingsail, solar
