Imagine a world where multiple touch-screens conveniently located will display information from everywhere on the vessel. Information is gathered from the engine, pumps, tanks, cameras, motors, hydraulics, winches, lights and climate control.
In a previous article, I detailed how we converted our ice box into a fridge/freezer onboard our Catalina 270. I can assure you, it is one of the best modifications we’ve made and truly classifies itself as an upgrade for both convenience and overall enjoyment.
Should you have 120VAC devices or appliances (vacuum, expresso maker, induction elements, wired tools) you’d like to run on your vessel when away from the dock you will need an inverter. An inverter takes in DC power and synthesizes 50 or 60Hz AC power at 120 or 220V.
When it comes to building sizable house battery banks, you will probably need more than one battery. Combining multiple batteries in series and/or parallel will allow you to construct a larger battery banks.

Figure 10 shows many of the fuse types commonly found on a vessel and the ones I use most commonly. (but not a complete list by any means). They differ by physical size, current capacity and AIC.
Many wires on a vessel are connected via a bolted lug. ABYC standard E-11 covers normal do and don’ts.
The other factor that affects wire size after the “how much current can it handle before burning up” question is, what is the voltage drop across the wire? At 120V if we lose a volt or two along the wire run it’s no big deal. At 12V if we lose a volt or two it’s a very different story.
I’m often asked to take a look at a survey to complete repairs at the request of a boat owner’s insurance company. Over the years, I’ve noticed that there are some items that are considered much lower ‘risk’, than others when identified on a survey.
This series deals with basic DC boat wiring concepts. From various articles and posts I see, and talking with boating friends, there seems to be mystery for many when it comes to boat electrics. I don’t intend this to be a deep dive but hopefully enough to take away some of the mystery.

Regal LS36 Luxury Crossover
By Andy Adams
Regal Boats’ new LS36 is what we call a day boat. Regal says the LS36 merges their luxury yacht series with their bowrider series and the result is the LS36. This comfortable bowrider is perfect for cruising the lake or hosting friends and family for the day on the weekend.
We feel the styling deserves mention right off the top. This is a big boat at over 37-feet on an 11’7” beam but the clean and almost traditional lines give the LS36 a timeless sporty look that we think, really sets it apart. It’s a Yacht-certified vessel. I counted approximately 21 places for people to sit! You would probably never take a crowd that big but it can certainly handle a gang.
Dufour 37
By Zuzana Prochazka
Every few years, boat builders update their lines with refreshed designs and new features that eventually proliferate throughout their entire offering. Dufour Yachts is in mid-process of such an evolution as the builder changes up their line of sleek sailing cruisers.
One sign of this transformation is the naming convention that is morphing from triple-digit numbers ending with a zero, to simple double-digits that one would guess designates the LOA – more on this later. The latest model in the refresh is the Dufour 37 which replaces the previous Dufour 360.

Hidden in plain sight: Western Lake Ontario
I start every article, story or TV segment about boating out of the biggest city in Canada the same way. Citing the multiple people who told me I would “quickly get bored of Toronto harbour” or that “there’s nothing to do in Lake Ontario” and that it was only a matter of time before I moved marinas to a much more appropriate setting just north of the city.
With all due respect to my pals who boat in Georgian Bay, I don’t foresee that happening anytime soon. Next year will be my tenth in Toronto Harbour and I love it more each year.

McDonald’s Canada founder, George Cohon, adores his Hinckley 48 Talaria
On a leisurely summer afternoon, what could be more relaxing than a cruise up the river aboard a stunning 48-footer with the most gracious host and a few very happy guests? If you have never met George Cohon; the founder of McDonald’s Canada, you might picture him as one tough hombre, a relentless business type who achieved staggering success.
But aboard McHappy III, the coolest boat on the lake, you’d never describe him as anything but charismatic, relaxed and enjoying life to the fullest.

Avator is Mercury’s next step forward in marine innovation and the 7.5e model is the first in a series of electric outboard products to be released in 2023. Mercury also plans to display concepts for its Avator 20e and 35e outboards, which will be in market later in 2023.
The Avator 7.5e outboard generates 750W of power at the prop shaft and produces similar speed and acceleration as a Mercury 3.5hp FourStroke outboard. Offered with tiller or remote steering, it’s ideal for powering many small boats, including tenders, jon boats, inflatables and kayaks.
New Gear: Compact Antenna Brings TV/FM Onboard
Televisions on a boat are increasingly commonplace. With the simple-to-install Glomex Avior VT300 Omnidirectional TV/FM antenna from GA Communications, it's never been easier to bring analog and digital broadcasts onboard—at a price that's hard to ignore.
The most noticeable feature of the Avior VT300 antenna is its compact white, anti-yellowing radome. At only 4" dia. x 8" H and 8.8 oz., it's specifically made for smaller boats that can't accommodate large TV antenna domes and only need short range reception, depending on height and conditions.
