  If you own a boat with a sail drive, there’s a critical piece of rubber maintaining your boats watertight integrity. As a marine surveyor, I’ve spoken with enough clients to know that the sail drive diaphragm (or hull seal) is one of the most overlooked preventative maintenance items on boats. Here is the reality: while saildrives offer smooth operation and easy installation, that rubber seal has a finite lifespan. Ignoring it isn't just a maintenance lapse; it’s a safety risk. What Exactly Is It? The saildrive unit passes through a large hole in your hull. To keep the water out while allowing the engine to vibrate and move on its mounts, manufacturers use a thick, reinforced rubber gasket. Some systems use a double-seal system . There is a primary inner seal that does the heavy lifting, and a secondary outer seal. There can be a water-sensor alarm fitted between these two layers to warn you if the first line of defense has failed. Service Life  Most manufacturers suggest r...

    As a marine surveyor working on the best coast, I’ve seen a lot of confusion lately regarding radio registration. While most Canadian boaters know about the MMSI (Maritime Mobile Service Identity) for their vessel, there is a newer, personal tool that is becoming essential for safety: the Maritime Identity (MI) . If you’re a commercial crew member hopping between tugs or a recreational kayaker exploring the Gulf Islands, here is what you need to know about navigating the National Maritime Information Database . What is a Maritime Identity (MI) in Canada? According to Innovation, Science and Economic Development Canada (ISED) , an MI is a unique nine-digit number that identifies you as an individual .   You can read more here Think of it like this: MMSI: Stays with the boat (the vessel's "license plate"). MI: Stays with you (your personal "maritime cell number"). It is programmed into your personal portable maritime radi...

    Ah, the MMSI. If you've ever stared at that "Distress" button on your VHF radio and wondered if it actually does anything, you’ve stumbled upon the most important safety tool on your boat. Think of an MMSI (Maritime Mobile Service Identity) as a digital fingerprint or a cell phone number for your boat. It’s a unique nine-digit number that identifies your vessel to the Coast Guard and other ships. In Canada, getting and managing this number is managed by Innovation, Science and Economic Development (ISED) Canada , and the best part? It’s completely free. Here is everything you need to know about setting yours up. Why Every Canadian Boater Needs an MMSI Without an MMSI programmed into your Digital Selective Calling (DSC) radio, that red "Distress" button is just a plastic flap. With it, the radio sends an automated digital Mayday that tells the Coast Guard: Who you are (vessel name and description). Where you are (if connect...

 As a marine surveyor one of the most common questions I get from prospective owners isn't about the state of hull or machinery - it’s about the paperwork. In Canada, the rules for Pleasure Craft Licensing (PCL) are governed by Transport Canada.   Information can be found on their website at https://tc.canada.ca/en/marine-transportation/vessel-licensing-registration   Image from the Transport Canada Safe Boaters Guide available at: https://tc.canada.ca/sites/default/files/2024-03/tp_511e.pdf Does Your Boat Need a License? Not every vessel on the water requires a PCL. The requirement is based on engine power. You must license your pleasure craft if is equipped with one or more motors totaling 10 hp or more even if it is temporary.   This includes personal watercraft and sailboats if they have an outboard or inboard engine meeting that power threshold. The Exception: If you choose to Register your vessel (rather than just licensing it), you do not n...

 Hello everyone and welcome to 2026!  As part of my marine surveying business I answer many client questions about all things boat ownership and vessel compliance.  There is so much to know about boat ownership and much of the information is hard to find.  I am starting this blog so I can publish answers to commonly asked questions so they can be shared amongst the boating community.  Please be in touch by placing comments, visiting my website at www.laylinemarinesurvey.com or contacting me by email at info@laylinemarinesurvey.com
