Ask Andrew: What To Look For If You Launch Late

Performing Engine Checks

The weather in early spring was not the best, so you may be just getting to launching. With all the rain in the eastern part of the country, a very pressing concern will be any water accumulation, and the associated potential structural damage. Any leaks in tarps, shrink-wrap or hatches may allow water to enter the boat and collect in the bilge. If you haven’t been allowed access to your boat to check on water accumulation, this should be your first priority once access is possible. Remove or clear any drains, use pumps (electric or manual) to empty the bilges, and check for any damage.

For most of us, power is a necessity  – both to start the engine, and to power any appliances. Check the batteries. This can be done using a multimeter set to check voltage. In order to power most equipment, and to start the engine, batteries should read between 12 and 13.5 volts. A marine mechanic may take this a step further and do a load test – which will measure the amperage output, as well as the voltage potential. The battery may need to be re-charged or reconditioned – check on this first, and get the process started if maintenance is required, because power will be needed in subsequent steps.

The single most expensive part of most boats is the engine. Check on this next. Before turning the key to see if it starts, perform some visual checks: check the oil dipstick and observe the level and colour. Remove the spark plugs, check their condition and clean the ends. Remove/replace fuel filters as necessary. Drain the antifreeze used in winterizing and dispose of it appropriately. In any outboard or stern-drive, check the lower unit oil and observe the level and colour. Run water to the engine and try starting and running the engine. Ensure it turns on/off, and shifts into forward and reverse appropriately. Check the emergency kill switch.

If the boat has a potable water system, add a cleaning agent to the water tank and flush it through the lines. Flush the system with fresh water and check for any leaks at corners, connections and faucets. Ensure that the hot water tank (if installed) is connected appropriately (especially important after winterizing), and check for leaks and heating operation.

Remove shrink-wrap and dispose of it appropriately. In most cases, this involves the cutting out and removal of any strapping, and bundling excess plastic together for recycling.

 Finally, tackle the more cosmetic jobs needed prior to launch. This includes bottom-prep for antifouling, antifoul application, hull polishing, repair of any fiberglass or gelcoat damage from the 2019 season, and cleaning of decks, cabins, berths, galley and head.

The delayed launch may mean that mildew or mould has accumulated under tarps and shrink wrap, as heat and condensation has had a greater chance of causing havoc. You may want to take some extra time and effort in cleaning, followed by touching up sealants, caulking and topside paint. It may also be a worthwhile pursuit to clean and oil any teak surfaces, or to renew varnish.

By Craig Ritchie

While Canadians may have been slower to warm to pontoon boats than our southern neighbours, that’s definitely changed as we see more of them gracing our waters every year. The latest data shows pontoon boats now represent around 30% of all new boats sold in Canada and it’s easy to understand why – with their interior space and tremendous versatility, pontoons are near-perfect family runabouts.

Cruising Georgian Bay’s 30,000 Islands: Canada’s Freshwater Paradise for Boaters

By Elizabeth Wilson, “Georgian Bay Beauties” (www.GeorgianBayBeauties.org)

The Plan

It’s a beautiful morning as we perform our pre-departure checklist, fire up the engines and prepare to release our lines. And if the long-range forecast of very low winds coupled with plenty of sunshine holds, that’s exactly what we need for the areas we plan to explore on this trip! 

We are departing Midland for a week of visiting some of the islands and anchorages within Georgian Bay’s “30,000 Islands” – specifically those along the western edge. These are the less protected islands which face toward wide-open Georgian Bay, where boaters often have to depart the small craft route and work a little harder at setting the hook but are then rewarded with magnificent western views, stunning sunsets, and so much to explore!
