Ask the Experts – Sacrificial Anodes

Ask the Experts Macleod

 

When metals are immersed in water and in close proximity to each other they produce an electrical voltage. When two dissimilar metals are in contact they form a galvanic cell, just like a battery.

If you want to protect both metals you need to introduce a third metal that is more active than the first two. The most active metal (zinc, aluminum or magnesium) becomes the anode to the others and sacrifices itself by corroding to protect the cathode – i.e. it sacrifices itself for the good of the other metals.

In this edition of Ask the Experts, we will explore what a sacrificial anode is, what it does and when to replace it.

Ask the Experts with Rob Macleod – Ablative Bottom Paint

This fall, while hauling boats Tim and I got into a discussion about the best way to prepare boats with ablative paints for winter storage. The question came up when I passed on having our boat’s hull power washed as Sojourn sat on the cradle. All the boats around Sojourn had harder bottom paints, which are intended for racing boats. The power washing, as you can see, took off all of the growth but left the bottom paint intact.

 

 

Fire Systems

Fire Systems

Engine room fires are mercifully rare, but every so often, one does occur. The engine room is the most likely place on your boat for a fire to get started and if the fire breaks out while you are out on the water, the lives of everyone on board are at risk.

Staying Afloat: The Power of PFDs

Staying Afloat: The Power of PFDs

Intrepid CY volunteers dive in to test the latest PFDs – and find that comfort and style make them more wearable than ever. Is it just my imagination – or are more boaters wearing PFDs more of the time today than they used to? It has been reassuring over the past few years to see life jackets, inflatables, floater garments and similar life-saving gear being worn regularly in settings where the sight would have been rare a decade or two ago.

New Boats: Beneteau Oceanis 34.1 – A Sleek, Good -Looking Delight To Sail

By Katherine Stone

There is nothing more that I enjoy than being with friends and messing about in boats. Messing about in brand-new boats on a champagne sailing day on Lake Ontario at the beginning of the summer doesn’t get any better. To have the new owner, Helmuth Strobel and Anchor Yachts dealer Pancho Jimenez aboard made it even more special, as they can also speak to what they truly enjoy about the boat. We keep our own boat in a harbour that has a long waiting list for boats over 35 feet, so this little gem would definitely fit the bill and feels like a much bigger boat. True to the spirit of the 7th generation Oceanis line, the 34.1 is built in Poland and replaces the 35.1. It is 1,000 lbs lighter, 14 cm narrower and has 29% more sail area.
