Some motorboats are fitted with inboard motor, inboard engines, others have an outboard motor installed on the rear, containing the internal combustion engine, the gear reduction, gearbox and the propeller in one portable unit. An inboard-outboard contains a hybrid of an inboard and an outboard, where the internal combustion engine is installed inside the boat, and the gearbox and propeller are outside. There are two configurations of an inboard, V-drive and direct drive. A direct drive has the powerplant mounted near the middle of the boat with the propeller shaft straight out the back, where a V-drive has the powerplant mounted in the back of the boat facing backwards having the shaft go towards the front of the boat then making a ''V'' towards the rear.

San Francisco Bar Pilots Association
San Francisco Bar Pilots Association is the official maritime pilot group for the San Francisco harbor and associated waterways. The pilots in the group are licensed and regulated by California Board of Pilot Commissioners. The Association was created in 1850 and is a member of the American Pilots Association. The association is the oldest purely maritime organization on the Pacific coast of the United States predating the oldest lighthouse in California erected on Alcatraz Island in 1854. The pilots were required by law to maintain a constant round the clock watch with enough pilots aboard a pilot boat on the bar to pilot any arriving ship safely into port. In 1910 the motor boat ''California'' was built for the pilots. In 1935 three schooner pilot vessels were maintained to provide rotating five-day watches on the bar near the lightship with two, the large schooner ''California'' and ''Gracie S.'' being regulars with ''Adventuress'' as reserve. At that time the pilot vessels ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pilot Boat
A pilot boat is a type of boat used to transport maritime pilots between land and the inbound or outbound ships that they are piloting. Pilot boats were once sailing boats that had to be fast because the first pilot to reach the incoming ship got the business. Today, pilot boats are scheduled by telephoning the ship agents/representatives prior to arrival. History Pilots and the work functions of the maritime pilot go back to Ancient Greece and Roman times, when incoming ships' captains employed locally experienced harbour captains, mainly local fishermen, to bring their vessels safely into port. Eventually, in light of the need to regulate the act of pilotage and ensure pilots had adequate insurance, the harbours themselves licensed pilots for each harbour. Although licensed by the harbour to operate within their jurisdiction, pilots were generally self-employed, meaning that they had to have quick transport to get them from the port to the incoming ships. As pilots wer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Section Patrol Craft
A Section Patrol Craft was a civilian vessel registered by the United States Navy for potential wartime service before, during, and shortly after World War I. Historical overview The SP/ID registration system In 1916, with World War I raging abroad, the U.S. Navy began a registry of privately owned pleasure craft and yachts that were available for patrol service in the event the United States was drawn into the conflict, which it eventually entered on 6 April 1917. Naval Registry Identification Numbers were assigned in a "Section Patrol" series beginning with SP-1 and ultimately extending to well over 4000. As the registration process continued, other types of ships and craft (such as cargo ships, tankers, and passenger ships) were included which were not suited or intended for patrol duty and for which the "Section Patrol" designation was clearly inappropriate, and these were generally given "Identification" ("ID") numbers in the same series as the "SP" numbers.

San Francisco Harbor
San Francisco Bay is a large tidal estuary in the U.S. state of California, and gives its name to the San Francisco Bay Area. It is dominated by the big cities of San Francisco, San Jose, and Oakland. San Francisco Bay drains water from approximately 40 percent of California. Water from the Sacramento and San Joaquin rivers, and from the Sierra Nevada mountains, flow into Suisun Bay, which then travels through the Carquinez Strait to meet with the Napa River at the entrance to San Pablo Bay, which connects at its south end to San Francisco Bay. It then connects to the Pacific Ocean via the Golden Gate strait. However, this entire group of interconnected bays is often called the ''San Francisco Bay''. The bay was designated a Ramsar Wetland of International Importance on February 2, 2017. Size The bay covers somewhere between , depending on which sub-bays (such as San Pablo Bay), estuaries, wetlands, and so on are included in the measurement. The main part of the bay measu ...
