magnetic compass The magnetic compass consists of a magnetized pointer (usually marked on the North end) free to align itself with Earth's magnetic field
magnetic course The course of a vessel after magnetic variation has been considered, but without compensation for magnetic deviation
magnetic deviation Compass error. The difference between the reading of a compass and the actual magnetic course or bearing due to errors in the compass reading. These errors can be caused by metals, magnetic fields and electrical fields near the compass. Prior to using a compass, magnetic deviation should be recorded for many different points on the compass as the error can be different at different points. The act of checking for magnetic deviation is called swinging.
magnetic north The direction to which a compass points. Magnetic north differs from true north because the magnetic fields of the planet are not exactly in line with the north and south poles. Observed differences between magnetic and true north is known as magnetic variation.
magnetic variation The difference between magnetic north and true north, measured as an angle. Magnetic variation is different in different locations, so the nearest compass rose to each location on a chart must be used.

mercator Type of projection of the globe used when making charts. Since the world is a sphere, it is impossible to draw accurate charts on flat paper. A Mercator projection shows all of the meridians as straight vertical lines rather than lines that would intersect. This is the type of projection used on a typical world map, but the distances become very distorted near the poles.

natural gas Short for compressed natural gas or CNG. A type of compressed gas used as fuel for stoves and heaters. CNG is stored in metal cylinders prior to use. CNG is considered safer than other types of fuel such as propane (LPG) because it is lighter than air and may rise into the sky in the event of a leak. Caution should still be used as CNG can collect near the cabin ceiling, potentially causing an explosion. Propane is available in more areas around the world than CNG so CNG is not often used outside of North America.

STAB Stability
stability Tendency of a ship to keep its upright position or return to it, to keep from heeling or rolling excessively, and the ability to quickly return upright after heeling.The force that holds a vessel upright or returns it to upright if keeled over. Weight in the lower hold increases stability. A vessel is stiff if it has high stability, tender if it has low stability. It is paramount that a vessel is stable in all aspects at all times. When cargo is loaded/discharged, the stability is monitored by a computer, which takes into account the weight and position of cargo within the vessel
stability sail A vertical pole on which flags can be raised.
stall Air is said to stall when it becomes detached from the surface it is flowing along. Usually air travels smoothly along both sides of a sail, but if the sail is not properly trimmed, the air can leave one of the sides of the sail and begin to stall. Stalled sails are not operating efficiently. To stop moving.

Terms of Sale - CIF CIF (Cost, Insurance and Freight) (...Named Place of Destination): A Term of Sale where the seller has the same obligations as under the CFR but also has to procure marine insurance against the buyer's risk of loss or damage to the goods during the carriage. The seller contracts for insurance and pays the insurance premium. The CIF term requires the seller to clear the goods for export.
Terms of Sale - CIP CIP (Carriage and Insurance Paid To) (...Named Place of Destination): A Term of Sale which means the seller has the same obligations as under CPT, but with the addition that the seller has to procure cargo insurance against the buyer's risk of loss of or damage to the goods during the carriage. The seller contracts for insurance and pays the insurance premium. The buyer should note that under the CIP term the seller is required to obtain insurance only on minimum coverage. The CIP term requires the seller to clear the goods for export.
Terms of Sale - CPT CPT (Carriage Paid To) (...Named Place of Destination): A Term of Sale which means the seller pays the freight for the carriage of the goods to the named destination. The risk of loss of or damage to the goods, as well as any additional costs due to events occurring after the time the goods have been delivered to the carrier, is transferred from the seller to the buyer when the goods have been delivered into the custody of the carrier. If subsequent carriers are used for the carriage to the agreed upon destination, the risk passes when the goods have been delivered to the first carrier. The CPT term requires the seller to clear the goods for export.
Terms of Sale - DAF DAF (Delivered At Frontier) (…Named Place): A Term of Sale which means the sellers fulfill their obligation to deliver when the goods have been made available, cleared for export, at the named point and placed at the frontier, but before the customs Terms of Sale border of the adjoining country. (continued)
Terms of Sale - DDP DDP (Delivered Duty paid) (…Named Port of Destination): "Delivered Duty Paid" means that the seller fulfills his obligation to deliver when the goods have been made available at the named place in the country of importation. The seller has to bear the risks and costs, including duties, taxes and other charges of delivering the goods thereto, clear for importation. While the EXW term represents the minimum obligation for the seller, DDP represents the maximum.
Terms of Sale - DDU DDU (Delivered Duty Unpaid) (…Named Port of Destination): A Term of Sale where the seller fulfills his obligation to deliver when the goods have been made available at the named place in the country of importation. The seller has to bear the costs and risks involved in bringing the goods thereto (excluding duties, taxes and other official charges payable upon importation) as well as the costs and risks of carrying out customs formalities. The buyer has to pay any additional costs and to bear any risks caused by failure to clear the goods for in time.
Terms of Sale - DEQ DEQ (Delivered Ex Quay, [Duty Paid]) (Named Port of Destination): A Term of Sale which means the DDU term has been fulfilled when the goods have been available to the buyer on the quay (wharf) at the named port of destination, cleared for importation. The seller has to bear all risks and costs including duties, taxes and other charges of delivering the goods thereto.
Terms of Sale - DES DES (Delivered Ex Ship) (Named Port of Destination): A Term of Sale where the seller fulfills his/her obligation to deliver when the goods have been made available to the buyer on board the ship, uncleared for import at the named port of destination. The seller has to bear all the costs and risks involved in bringing the goods to the named port destination.

Terms of Sale - EXW EXW (Ex Works) (…Named Place): A Term of Sale which means that the seller fulfills the obligation to deliver when he or she has made the goods available at his/her premises (i.e., works, factory, warehouse, etc.) to the buyer. In particular, the seller is not responsible for loading the goods in the vehicle provided by the buyer or for clearing the goods for export, unless otherwise agreed. The buyer bears all costs and risks involved in taking the goods from the seller's premises to the desired destination. This term thus represents the minimum obligation for the seller.
Terms of Sale - FAS FAS (Free Alongside Ship) (…Named Port of Shipment): A Term of Sale which means the seller fulfills his obligation to deliver when the goods have been placed alongside the vessel on the quay or in lighters at the named port of shipment.This means that the buyer has to bear all costs and risks of loss of or damage to the goods from that moment.
Terms of Sale - FCA FCA (Free Carrier) (… Named Place): A Term of Sale which means the seller fulfills their obligation when he or she has handed over the goods, cleared for export, into the charge of the carrier named by the buyer at the named place or point. If no precise point is indicated by the buyer, the seller may choose, within the place or range stipulated, where the carrier should take the goods into their charge.
Terms of Sale - FOB FOB (Free On Board) (…Named Port of Shipment): An International Term of Sale that means the seller fulfills his or her obligation to deliver when the goods have passed over the ship's rail at the named port of shipment. This means that the buyer has to bear all costs and risks to loss of or damage to the goods from that point. The FOB term requires the seller to clear the goods for export.

through hull Fittings attached through the hull to which a sea cock and hose, a transducer, or other device is attached. Through hulls are used to expel waste water, such as from a sink, to let sea water in, such as for engine cooling, and to allow placement of sensors such as depth gauges. A sea cock is attached directly to the through hull before any hoses are attached so that the flow of water can be easily shut off if the hose fails. Plugs should be available to force into a through hole in case the through hole fails. Transducers should be equipped with caps to place over the hole should the transducer itself need to be removed.
