Sea Blow Go SlowDid YOU Know?

For the sake of boater and whale safety, it is really important to know that baleen whales, like Humpback Whales, are very different from whales, dolphins and porpoises who have teeth. Toothed cetaceans, like Orca, have biosonar by which they can form an acoustic image of their surroundings. Baleen whales like Humpbacks do not have this biosonar and are often oblivious of boats and fishing gear.

The danger of collision is also enhanced because of the large size of baleen whales and because of their unpredictable travel patterns. Whales can surface unexpectedly after long - or very short - dives. Humpbacks in particular can suddenly become acrobatic or may be resting just below the surface.

It is essential to be vigilant for signs of whale presence. Look for blows and aggregations of birds, which can indicate there is a lot of feed in the area and thereby a greater chance of whale presence. Be on the lookout for vessels flying the Whale Warning Flag. Know the areas of high whale density. And, if you do signs of whale presence, give the whales plenty of room (minimum 200 meters), and SLOW DOWN! Collisions can be tragic for both whales AND boaters.

For information on how to reduce risk of collision and to know what to do, and not do, regarding whale entanglement, see the following resources:

• CPS-ECP boater education resource “Boaters and Marine Mammals - Safety and Stewardship”.

• A summary of the national Marine Mammal Regulations and boater best practices.

Beneteau Oceanis Yacht 54By Zuzana Prochazka

Beneteau saw an opportunity to add a little thrill to any cruising adventure, so they took the hull of the First 53 racer (introduced just last year), and with a few fashionable changes, created the Oceanis Yacht 54, the new entry-level of Beneteau’s swanky Oceanis Yacht line. The result is a performance cruiser that sails like a witch and looks like a grande dame.


Roberto Biscontini is the naval architect and Lorenzo Argento created the details of the exterior and interior design.

Riverest MarinaThe new owners of L’Orignal Marina offer boaters a new destination. Located in a charming francophone village in Eastern Ontario, this joined marina and restaurant venue is the ambitious initiative of long-time entrepreneur André Chabot and biologist Alexandra Quester, both residents of L’Orignal.

The purchase of the L’Orignal Marina was made official in November 2020. The new year was barely underway when all 50 available slips were already reserved. No wonder the addition of member and visitor slips is already planned for the 2022 season – the 2021 count is up to 62 power and sail already. At the moment, the Riverest Marina offers boaters a stop where they can launch their boat...

Galvanic CorrosionIt’s a scary thought – but whether your boat is made of wood, fiberglass, aluminum or composite – it’s slowly deteriorating under you. Part of this is the nature of the marine environment: Sun, moisture, waves, wind, movement and vibration all contribute to components breaking down.

But there are other factors that are much more concerning and act at a significantly faster rate that the environment can take credit for. One of these is commonly spoken of, but not terribly well understood: Corrosion. As boaters, we’re concerned with two main types of corrosion: Galvanic and Stray-Current. This edition will focus on galvanic corrosion – in two weeks, stay tuned for info on stray-current.

Mia and Caleb's EngagementOn July 23 last year, CYOB published a piece on a beautifully restored 1967 Trojan 42 Motor Yacht in Oromocto NB. (That piece was also expanded in CY magazine later in the year.)

One of our Canadian Yachting contributors, Denise Miller, had shared the article on my social media and a young man reached out and asked if she could connect him with the owners of the boat, Dave and Barb. Denise leapt into action and Dave and Barb were thrilled. They concocted a plan that the young lady, Mia, thought she was coming to model for a sales brochure for Dave to do charter tours.
