Petrol or diesel. Due to availability and convenience of handling, petrol (or gasoline) and diesel (or distillate) are the most common small vessel marine propulsion fuels. Larger vessels often use a cheaper and less refined tarry fuel oil requiring heat to liquefy sufficiently for the combustion process.
The commonly used signals are: FireThe continuous ringing of a bell. To emergency stations Seven short & one prolonged blast on the horn. To abandon shipOne short & one prolonged blast on the horn repeated three times. Do not jump overboard if you hear seven short & one prolonged blast on the horn.
1. Under Survey, bilge systems must be able to pump and drain any water-tight compartment in the vessel. 2. All pumps must be self-priming. 3. Power pumps may be powered by either an auxiliary internal combustion engine, or an electric motor. However, when more than one pump is specified, each must have its own separate power source.

Parameters such as centre of gravity and centre of buoyancy have been used in describing transverse stability, so far. They can also be used to describe longitudinal stability. LCB and LCG. Figure 16 LCB Forward of LCG - Vessel trims by the stern. In Fig 16 LCB is the longitudinal centre of buoyancy.

To find the course to steer: 1. Lay of the required course to make good, "AB". 2. Plot one hour's set and drift from "A" to "C". 3. With centre "C" lay off ship's speed - the distance she will travel through the water in one hour - to point "D" 4. The direction "CD" is the true course to steer from "A" 5.

Turn in a smooth, a period when the waves are momentarily flatter than the prevailing sea condition. Start the manoeuvre as soon as the wave crest has passed the vessel (1). Reduce engine speed to allow the sea to pass quickly. Turn the wheel hard over and turn the vessel in the trough between the crests.
With centre "C" lay off ship's speed - the distance she will travel through the water in one hour - to point "D" 4. The direction "CD" is the true course to steer from "A" 5. The distance "AD" is the speed that will be made good 6. To find the E.T.A. at "B" the distance "AB" is divided by the speed made good "AD".

Example Greenland is smaller than Australia on the Globe, but appears on the Mercator projection as the same size. The main feature of the Mercator projection is that both meridians and parallels are expanded at the same ratio with increased latitude. Expansion is the same in all directions and angles are correctly shown. Rhumb lines

These are summarised below. General Design. • All vessels except twin screw vessels and vessels where the normal means of steering is a hand tiller shall be fitted with two independent means of steering. • The steering gear shall be of adequate strength to steer the vessel at maximum speed both ahead and astern.

A classic pattern for fog formation is to have rain falling late in the day, followed by the arrival of a high-pressure system overnight. Advection fogs are formed by warm moist air moving over a cool surface, such as sea fog. Evaporation fog or sea smoke is caused by cold air passing over warmer water.
