Basic Boat Terminology

At first all the terms used in the marine world may seem intimidating and confusing, but mariners use these terms so that everyone working on, or with a vessel can understand each other. In an emergency it is vital that everyone understands each other as quickly as possible. You may be the only crew member on your vessel but in an emergency, you may need to communicate with other vessels and the coast guard who can assist you. In the marine industry there is a lot of jargon and terms that are industry specific, but this is true in many other industries. Whether you are new to the industry or if you have new crew on board the vessel it is important that everyone can effectively communicate when working on or around boats.

Here are some basic boat terms that you should understand:

Abaft – Toward the stern (toward the rear or back of a boat).

Abeam – A direction at right angles, 90o to the side of the boat.

Aft – A directional term, towards the stern of the boat

Ahead – A directional term when the boat is moving forward

Amidships – The central or middle area of a boat

Astern – In the direction of the back of the boat; also, the movement of the boat going backwards.

Athwartships – A line or anything else running from side to side across the boat

Ballast – Added weight in the boat’s bottom to provide stability.

Beam – A measure of a boat’s widest part of the hull, the width of the boat.

Below – Moving from an upper deck to a lower deck.

Bilge – The deepest area inside the hull of a boat

Bow – The front end of a boat

Chine – The angles on the boat’s hull below the water line. It is “soft” if it is rounded and “hard” if it has sharp angles and is squared off. Chine affects the boat’s speed and turning characteristics.

Displacement – The amount of water a boats hull and load pushes aside equal to the weight of its hull and load.

Draft – Is the depth of the boat from the waterline to the bottom of its keel. The draft is the depth of water necessary to float the boat. Watch out for your outboard skeg, it protrudes lower than the draft of the boat!

Fenders – A cushion-type object between a boat and the dock/ or another boat to minimize damage and absorb shock

Forward or Fore– A directional term meaning towards the bow of the boat.

Freeboard – The distance between the waterline and the gunwales or deck openings

Gross tonnage – A volume measurement of the total enclosed space within a boat

Gunwales – Top edge of the side of a boat (pronounced gun ‘al)

Hatch – An opening in the deck or top side of a cabin which usually has a watertight closure.

Heel – The temporary leaning of a vessel to port or starboard caused by wind, seas or turning forces

Hull – The part of the vessel excluding any super structure and determines the performance of a boat and keeps it floating.

Inboard – From either side toward the centreline.

Keel – The central longitudinal beam which the hull is built up from.

Lazarette – A compartment on a boat at the stern end of a boat usually used for storage.

Leeward – The opposite side or direction from where the wind is blowing, away from the wind.

Length Over All (LOA) -The length of the boat from its forward most part to its after most part in a straight line including outboard engines, davits and bow sprits. This does not change according to the way the boat sits in the water.

Lifelines – Lines or railings, erected around the edge of decks.

List – The leaning of a vessel to port or starboard due to uneven weight distribution or bad design

Outboard – From the centreline of the boat toward either port or starboard side.

Pitching – When a boat rocks in a fore and aft movement.

Planing – When a vessels hull is ‘skimming’ along the water’s surface.

Port – The left side of a boat facing forward with a red side light

Quarter – If you are standing at the stern looking forward, you call the right rear section the starboard quarter and the left rear section the port quarter.

Rigid Hull Inflatable Boat (RHIB) – A vessel with additional ‘soft’ floatation tubes attached to a solid hull.

Roll Period – The amount of time it takes for a vessel to roll from one side to the other and back again.

Scupper – An opening in the sides of a boat at deck level to allow water to flow overboard

Semi Displacement – This type of hull uses the characteristics of both a planing and a displacement hull to move through the water.

Starboard – The entire right side of a boat, from bow to stern and has a green sidelight.

Stern – The rear of a boat is the stern. When you move toward the stern, you are going aft. When the boat moves backwards, it is going astern.

Stiff Roll – Is when a vessel has a ‘quick’ roll period and indicates a stable boat

Tender Roll – Is when a vessel has a ‘slow’ or lengthened roll period, it may be quick to roll to one side but slow to come back up right. This type of roll may indicate danger and that the vessels stability is compromised.

Transom – The transom at the stern of the boat is wide, flat, or curved. The shape of the stern affects the speed, hull resistance, and performance of the boat.

Trim – The relationship between a ship’s draft forward and aft.

Underway – When a vessel is not made fast to the dock, not at anchor and not aground

Waterline Length (LWL) – Is the distance from the bow to the stern, measured at the water line when the boat is stationary. Note that this length changes as the boat rides high or low in the water.

Windward – In the direction from which the wind is blowing, toward the wind.

Enroll in the Small Vessel Compliance Program

The Small Vessel Compliance Program is a voluntary program that will help you operate a small non-pleasure craft, small vessel or tug safely and legally.

As a vessel owner or operator, Canadian law makes you responsible for knowing, controlling and managing the risks related to your vessel.

Once a Marine Safety Inspector completes a technical review, you will receive a blue, orange or green decal to display on your vessel and a letter of participation. This decal and letter will show that your vessel is enrolled in the program.

You will receive your decal within 45 working days of Transport Canada receiving all your documents and completing a technical review. You’ll need to renew your enrollment every 5 years.

Changes coming to the Safety Management Regulations in 2023 will affect most Canadian Domestic Vessel owners!

The existing Safety Management Regulations, published in 1998, apply to approximately 96 vessels in the Canadian fleet. The proposed Regulations will apply to approximately 16,000 Canadian vessels, including all commercial passenger vessels, aiming to ensure a larger portion of Canada’s fleet adheres to a higher safety standard. 

The proposed regulations would repeal and replace the existing Safety Management Regulations, broadening the application of safety management systems to the Canadian domestic fleet. This would also address the Transportation Safety Board’s recommendations to require all commercial vessels to have a Safety Management System.

The proposed regulations would divide the Canadian fleet into five classes, each with varying levels of safety management systems and oversight requirements. The class in which a vessel is placed would be determined by its size, type, and operation. The Canadian fleet would be divided into five classes:

Class 1: The current Regulations apply to all International Convention for the Safety of Life at Sea vessels, and the companies that operate them. There are no changes for class 1.

Class 2: Canadian vessels 500 gross tonnage or more and the companies that operate them, gross tonnage being a measure of the vessel’s overall size, and any vessels that carry 50 passengers or more.

Class 3: Canadian vessels longer than 24 metres, except for vessels in classes 1 or 2.

Class 4:

  • A: Canadian vessels greater than 15 gross tonnes, except vessels that are in classes 1 to 3, or
  • B: Canadian passenger vessels and towboats of not more than 15 gross tonnes, except vessels that are in classes 1 to 3.

Class 5: Canadian vessels 24 metres or less, less than 15 gross tonnes, and are not in class 4 B.

SDV-BS

MEDA3 is replaced by the SDV-BS

MEDA3 certificates will continue to be valid

  • We offer a new Marine Emergency Duties certification – the Small Domestic Vessel Basic Safety instead of the MEDA3.
  • It’s basically the same course but with a new name.
  • It’s valid the same as the MEDA3 and MEDA3 certificates will continue be valid. 

What does this mean for you?

If you already have the MEDA3, you do NOT need to retake the course. Just hang onto your MEDA3 certificate! (we can still issue replacements but there is charge)

If you’re signed up for an upcoming MEDA3 course, you will receive a SDV-BS certificate instead of a MEDA3 certificate. The SDV-BS has the same validity as the MEDA3.

The full name for the new certification is small non-pleasure vessel basic safety, but Transport Canada decided to use the catchy name Small Domestic Vessel Basic Safety for short!!!!!

For more information about the validity of Marine Emergency Duties certificates here’s a link to the Marine Personnel Regulations:
https://laws-lois.justice.gc.ca/eng/regulations/sor-2007-115/page-30.html#h-730549

Please see below an excerpt from Transport Canada publication TP4957, outlining the equivalency between the new and the old certifications. A full PDF copy of TP4957 can be found on our webpage https://marinetrainingbc.com/wp-content/uploads/2020/10/TP-4957-as-on-6th-Feb-2017.pdf

Just when you thought it was safe to go out on the water……..

Just when you thought it was safe to go out on the water…..Transport Canada has proposed some changes to the SVOP

OH NO NOT AGAIN!

The validity of SVO certifications may be extended to operators of larger vessels (up to 12 meters long). 

Nothing is finalised yet, but here’s what we know so far:

  1. Any changes to the SVOP course will not come into effect until 2025, at the earliest
  2. Existing SVOP certificates will still be valid, but holders may have to take additional courses if they want to operate larger vessels (more than 5GT, less than 12m)
  3. The SVOP will probably be a few hours longer

We hope these changes will mean a “new and improved” SVOP for bigger boats. More information is available on our webpage:

Salvage rights – Abandoned vessels – know your rights

Here’s a link to a Transport Canada PDF outlining the procedure for if you find an abandoned vessel (wreck)
http://www.tc.gc.ca/media/documents/marinesafety/found.pdf

Any person taking possession of a wreck (i.e. salvaging) must report a found wreck. If you salvage a wreck, you are entitled to reasonable salvage costs and expenses for your efforts. The vessel owner is liable for these expenses. If the owner cannot be found, the salvage award may be the wreck, or all or part of the proceeds of its sale, but will not exceed the value of the wreck.

As a boat owner you are responsible for disposing of your boat.
