Enviro Dropping AnchorAs the name implies, marine parks include aquatic as well as terrestrial park areas. Protection of the seafloor is even more essential than conservation of park terrestrial features because the seafloor damage is unseen.

The seafloor in marine parks provides vital habitat for a host of creatures: sea stars, sea urchins, sea cucumbers, crabs, shrimp, barnacles, mussels, chitons, snails, nudibranchs, tubeworms and ribbon worms, rockfish, sculpins, flounders and even the Giant Pacific octopus. That habitat exists at two levels:

• On the seafloor, eelgrasses grow horizontally in dense, extensive beds or meadows that provide food, shelter and protection for many organisms, including shellfish. Elsewhere, algae (commonly, “seaweeds”) cover the intertidal and a significant proportion of the subtidal seafloor. These algae also provide significant habitat and food.

• In the water column, kelps form high dense canopies above the seafloor. Like the seafloor flora, they provide habitat for many invertebrates and fish.

Those plants and their associated organisms play a vital role in the integrity of nearshore ecosystems in our marine parks. Given the diversity of marine life, anchoring in marine parks should be carefully controlled to minimize ecological impact. Some non-government organizations have attempted to make mooring less damaging. For example, the BC Marine Parks Forever Society (Footnote 1) has provided stern ties in nine (footnote 2) of the fourteen popular marine parks. However, stern tying does not eliminate anchoring damage - it still requires setting an anchor off the bow.

Efforts have been made in some local marine parks to educate boaters about anchor damage. Sidney Spit has signs on the dock asking boaters to avoid anchoring in less than 10 metres of water. However, voluntary compliance is inadequate because anchoring continues. A 2006 study at Sidney Spit (footnote 3) reported that, even when unoccupied mooring buoys were available, 30% of overnighting boats nevertheless chose to anchor, with 85% of those boats anchored in sensitive eelgrass beds.

Allowing (and, in light of the mooring buoy fee, actually encouraging) anchoring is directly contrary to sound conservation of seafloor life in our marine parks.

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.

Design

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.
