I first learned about radar reflectors when I read the International Regulations for Preventing Collisions at Sea (a part of the Canada Shipping Act) some 20 years ago.

Since the initial article of this column we have identified a wide range of apps and accessories for your iPad, including numerous marine navigation apps like iNavX and Navionics as well as a number of other marine related apps and accessories. One feature we have not yet considered is the use of apps for racing. Whether you race professionally or for fun there are apps that help take your racing to the next level.
Since the initial article of this series we have looked at the iPad and its use as a marine navigation instrument. We have discussed its functionality, available apps, relevant hardware and compared it to traditional charplotters. This focus on iPad led one of our readers to an interesting question that we have yet to address.
Question: Why has the focus been solely on the use of iPads for marine navigation rather than Android devices?
In Going iPad with Marine Navigation we concluded that iPads provide a modern platform for marine navigation. No we shall explore how functional an iPad is in comparison to standard chartplotters.

Question: Is it possible to mount, protect and charge your iPad during marine navigation.
Answer: Yes, but it often requires some creative thinking and typically purchasing separate accessories for each duty.
Not many of us need to stay connected to our global business empire while cruising (the 0.01 %?), but a pretty sizeable percentage of boat owners do need to keep in contact whether for business or family reasons.
Is iNavX the superlative marine navigation app?
There is a good deal of hesitancy and lack of understanding as to whether an iPad can fully replace existing navigation equipment. Quite simply put the answer is yes!
Sunshine flooded the waters separating California’s Catalina Island from Channel Islands Harbor, and Capt. Tom Petersen, skipper of the well-equipped Sea Ray 55 Sundancer Valkyrie, was leading a small flotilla when an unexpected fog bank quashed visibility. While Valkyrie carries the latest Raymarine kit (Petersen is a Raymarine Pro Ambassador), including a 12 kW, six-foot, open-array high-definition radar, Petersen’s companions weren’t electronically fortified. “I sat behind the other boats, watching them on my radar and maintaining radio contact,” said Petersen.
Boaters who prefer to be on the hook, such as ourselves in our Islander 36 sailboat Holole’a, greatly extend their cruising experience. There are many more bays and nooks and crannies available when using the anchor. And it is free! However, the one big issue is electrical power. The boat has to be self-contained for storing electrical power (batteries), recharging the batteries, and providing 120 Volt electrical power (main engine with alternator or dedicated genset). Solar panels can help recharge batteries also.Most boats use deep-cycle batteries for the house battery system. These are batteries that can tolerate hundreds of cycles of a 50% discharge. Without getting too technical, they are generally robust batteries of lead-acid, gel-cell, or AGM (absorbed glass matt) construction. The common physical sizes for 12 volt systems can vary from Group 24 (common car size), to golf-cart 6 volt batteries (connect 2 in series for 12 volts) up to massive and very heavy 4D and 8D. Battery banks can be added in parallel for more capacity.

Viko S35 – A sexy, affordable racer-cruiser
By Katherine Stone
I am lucky to have the opportunity to helm many types of boats. I am even more lucky to sail boats on champagne fall days when many boats are either being hauled for the winter, or are already under shrink-wrap.
Not only are there great winds – usually offshore, but welcome sunshine and open waters with few boats out enjoying the last days of September. Joining me for the test sail of the Viko S35 was the former publisher of Canadian Yachting, Greg Nicoll, and the Canadian Viko Yachts representative, Eric Beauregard, who had driven down from Montreal.
Four Winns H4
By Andy Adams
The well-known Four Winns brand is now a part of the international boatbuilder Groupe Beneteau and the new H4 is a great example of how the design and engineering resources of Beneteau can up the game even for a brand like Four Winns that has a long and distinguished history.
The Cadillac Michigan-built H4 is a brand-new design this year and we think it's especially handsome. The vertical stem bow is all new and innovative. It is a design feature that was chosen to give Four Winns and the H4 a sense of modern and contemporary look while the stern remains more traditional.

West Side Story
by Jennifer M. Smith, drone photos by Alex Nikolajevich
It was the last day of August and we were in Little Current heading south. Our Lasalle winter haul out was still over a month away. The question was: where to now? Friends in Meaford often suggested we sail in for a visit. We never had because we’d always moved north-south on the east side of Georgian Bay. This year we were up for something different. This was the perfect opportunity to cruise the west side of the bay.
We made the 10 a.m. bridge out of Little Current and motor-sailed east southeast in light northerlies. We’d often sailed past Snug Harbour, a nearly land-locked anchorage on the north side of Lansdowne Channel because the chart suggested we’d never make it in there with our six-foot draft.

What to look for and ask about as you plan your vacation times. You’ve invested thousands and thousands of dollars into your boat so naturally, you want to find just the right spot for her to live, and where you can enjoy her to the maximum. Marinas and yacht clubs are just like people, no two are completely alike and finding the one that’s perfect for you, may make you feel a little like Cinderella – searching for the shoe that fits just right.
It’s okay to take your time on this search because the marina you choose is arguably as important a decision as the one to buy your boat.

Thrusters can make docking easier
By Andrew McDonald
Corners like it’s on rails. You can almost see it. A car with a low centre of gravity takes a curve. The driver shifts through the gears and exits the bend with speed and grace. Stops on a dime. That same vehicle smoothly downshifts and comes to a complete stop as though hitting an invisible barrier.
Most of our sailing metaphors evoke thoughts and feelings of strong winds pushing a sleek racer faster, or perhaps the crew tacking or gybing around a mark. We don’t seem to have the same colourful expressions to describe the movement of a power or sailing vessel at slow speeds.

SailGP, the international racing series featuring high speed F50 wingsailed catamarans, is partnering with RS Electric Boats – sister brand of sailboat manufacturer RS Sailing – to use the Pulse 63 electric RIB as chase, coach and support boats.
RS Electric Boats will supply SailGP with four Pulse 63s, which were designed to be electric boats from the outset. The unique aerodynamic hull form is designed to support the weight of the batteries while allowing rapid acceleration, functional speeds up to 23 knots and ample range.
