Sensors usually include, in addition, one or more compass, altimeter (barometric) and GPS, along with optional additional sensors such as optical flow sensors, airspeed indicators, laser or sonar altimeters or rangefinders, monocular, stereoscopic or RGB-D cameras. Sensors may be on the same electronic board, or external.
Surf fishing is land-based game fishing while standing on the shoreline or wading into the surf zone. A general term, surf fishing may or may not include casting a lure or bait, and refers to all types of shore fishing – from sandy and rocky beaches , rock jetties , or even fishing piers .
A jetboard is a motorized surfboard, where the rider controls the speed using a handheld remote control (wireless or tethered) and uses the bodyweight transfer to maneuver the board. The driveline typically consists of a water jet module (similar to what is found in a PWC), and either a combustion engine or a battery powered electrical motor ...
A chart showing various shapes of the bottoms of surf boards. The surface of the board that rests on the water is usually flat or concave but sometimes convex. The bottom can also feature channels, chines, steps and other planing features shaped into the board in order to maximize, direct or alter water flow across the board's bottom surface.
Thill Fishing Tackle, maker of balsa floats, was acquired in 1992, and further acquisitions followed with System Tackle Manufacturing in 1997, Old Bayside Fishing Tackle in 2003, and Muskie Greats Tackle (G/T) in 2004. The addition of System tackle and Old Bayside added extensive ice fishing and inshore saltwater products to Lindy's product ...
In addition to the power consumed by the radar, the thrusters which propel the vessel are electric and require substantial power. The maximum speed is approximately 8 knots (9.2 mph; 15 km/h). To support this and all other electrical equipment, the vessel currently has six 3.6-megawatt generators (12-cylinder Caterpillar diesels).
A surfboard fin with dimples creates a turbulent flow a fin without Dimples is more a laminar flow. Turbulent flow has more adhesion so when the surfer starts to turn, the dimpled fin surface delays the flow separation, reducing cavitation (the separation bubble) allowing the foil to maintain performance. When the surfer is turning at high ...
A balestron rig is a sailplan involving a boom that extends forwards of the mast and is pivoted on it. It is a balanced rig. [1] It involves a mainsail and a smaller jib on an unstayed mast. [2] Mainsail and jib are controlled by a single sheet. The rig was extensively used on model boats but has recently been used of full-sized vessels. [3]
