Ask Andrew: Mid-winter boat hugs

Obvious Engine Damage

Sometimes I wonder if my boat is thinking about me. Do do ever wonder, too?

We’re never going to know how our boats really feel about us, but we can keep the romance alive, especially during the dreary days between Valentines and St Patrick’s Day by checking in. Go for a visit, even if it’s a short one. Say hello and daydream of warm summer days together.

While you’re there, though, you may want to work your way through a checklist to make sure that all is well until spring.

Over a number of years in the marine industry I’ve made some interesting discoveries when I’ve done mid-winter boat checks. Here’s a short list of the most impactful:

  • A warehouse used for indoor boat storage was hit by thieves who removed 10 + stern drive units in a single evening.

 – A 27’ sailboat filled with so much water  that the hull became distorted against the cradle pads and had to be written off by the owner’s insurance company. The water got in somehow, despite the shrink-wrap remaining intact.

  • Plugs removed from the stern drive or sail drive allowing all of the gear lube to drain.
  • Raccoons settling in for winter – creating a home and nest for newborns.
  • A boat/trailer at a storage facility tipped over completely during a wind-storm. Staff were not regularly present, so the boat remained tipped over for a number of weeks, causing permanent damage to both the boat and trailer.

All of this to say: maybe that trip to check on your boat should be just as practical as it is nostalgic and dream-filled. Here’s a more comprehensive list of things to check on during your visit:

raccoons made themselves at home!

  1. Check for overall integrity: is the shrink-wrap/cover/tarp in place and secure? Is it chafing against exposed parts? Are the tie-downs secure and strong?
  2. If the boat is on a cradle or stand: is the boat level, and supported well and equally by the cradle pads? Is the cradle itself resting well on the ground?
  3. If the boat is on a trailer: is the trailer secure, blocked, and do the tires have adequate pressure? Are the tie-downs secure and winch straps secure?
  4. Check the hull: Is it supported adequately by the pads or bunks? Do you notice any water seepage, blistering or freezing damage? Any cracking or damage caused by the boat ‘settling’?
  5. Check the exterior machinery: Is the prop secure? If the shaft is exposed, is it in good condition? In the case of a stern/sail-drive, is it secure, with plugs in place? Any exterior damage to any components?
  6. Inside the boat: Any evidence of critters making a home? How is the ventilation, and moisture level? If you’ve added a product to reduce humidity, is it working? Does it need to be replaced? Are the vents adequate to allow air flow? Any mildew forming? Excess condensation?
  7. Check the batteries: Are any battery cables in contact with the battery? At least one terminal (preferable the negative) should be removed? Is the exterior of the battery case bulging on any side?
  8. Check the engine(s) – inboard, outboard, diesel or gas – check the exterior for any cracking or leaking fluids. Visually check hoses and fuel filters. Check the block (the sides of the engine) for any visible cracks, stains or leaks
  9. Check the bilge: check for excess water, damage, cracks, mildew, etc. A shop vac is a handy tool in the event that water is present.
  10. Check the hatches, doors and locks – make sure all is secure before you leave!
  11.  Finally – in the event of any damage, check your insurance policy and put a recovery plan in place

A last note: This is a good time to dream. By beginning plans now, you can hopefully avoid the spring rush on lining up contractors and materials. This is also a great time to think of the steps you need to get to go on that dream adventure once the boat is in the water.

Enjoy the visit, and say hello to your boat for me.

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

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!
