Canoeists often cite the stern of the boat as the position from which the steering of the boat is done, while the person paddling in the bow position is responsible primarily for power production.
A boat is generally labeled in four directions: the stern, or rear; the bow, or front; the starboard side, or right side; and the port side, or left side. Many modern crafts feature a light at the rear of the ship for navigation and to make other ships aware of its presence during the night.
The aft, or back, light usually glows white. On smaller vessels, propulsion devices may be located in the stern; motorboats, for example, often feature outboard motors that extend into the water off this part of the vessel.
Today, they are building ocean-going vessels that have transom sterns. What is a transom stern? The shape of a transom stern is basically flat all the way to the waterline. This shape produces greater space in the aft deck area. It is not just easier and simpler to construct, but it also improves the flow of water around the stern.
This type of stern design, especially its underside, affects the propulsion efficiency of the boat. If there is less turbulence in the space between the outer shell of the ship above the propeller and the propeller itself, its efficiency will increase.
But the deck of transom sterns will easily get wet when the ship goes in reverse mode and during heavy seas. In such cases, the water is damped up. What is a cruise stern? When it was first designed, a cruiser stern was intended to reduce the height of the steering gear located beneath the armor deck. This type of stern has a curved profile going upwards, coming from the aft perpendicular to the poop or main deck. The cutaway in a cruiser stern is not like that of a counter stern.
Its rudder is placed below the waterline, where it is fully submerged. This type of stern has improved resistance capabilities compared to the merchant stern. It is more hydrodynamically efficient, and its profile is more aesthetically pleasing. What is an elliptical stern? The elliptical stern is also called the counter or merchant stern. It was the conventional stern design for cargo ships in the early 20th century. The deck line and the knuckle line, when viewed from above, have an elliptical shape.
It has an upward and curved profile. The cutaway for the counter stern is located above the waterline. Therefore, this stern has an exposed skeg and a pronounced aft overhang. This type of stern allows for larger deck space.
It offers an excellent aesthetic option to the owner as well. Reserve buoyancy of the ship is also increased measurably with counter sterns.
The column of water around and behind a moving pleasure craft , which is set into motion by the pleasure craft advancing through the water. Smooth track left by the passage of a vessel.
PFD Personal Flotation Device is a personal buoyancy aid designed to provide an individual with additional floating ability while in the water. More information on PFD. The main body of a vessel from the deck down. It does not include rigging, superstructure, machinery, or equipment. It's whatever is used to steered the boat , which is generally a tiller or a wheel.
The distance from the waterline to the upper deck level, measured at the lowest point of sheer, where water can enter the boat or ship. A vessel which has right-of-way during a meeting, crossing, or overtaking manoeuver, shall maintain her course and speed. A lifejacket comes only in red, orange and yellow , in order to make you much more visible while in the water.
It has more floating ability than the PFD, with the added advantage of turning you on your back, even while unconscious. Find a Cruise. Cruise Tips. You may also like Dismiss.
