Engine technology to watch for

With the recent release of the final report of Nigel Calder's HyMAR project, marine internal combustion / electric hybrid powertrains are making waves once again- and not necessarily in a good way, as Calder's team found that the benefits of the expensive hybrids were limited to a relatively narrow, low-speed operating regime. We've known for quite a while that the major advantages of gas/electric and diesel/electric hybrid cars- namely, instant start/stop and regenerative braking- don't apply to boats. We've also known for quite a while that hybrid systems only make economic sense aboard ship if the house loads are comparable to, or larger than, the power required for main propulsion.

Tech addicts need not fear, though: There are many other fuel-saving and pollution-reducing technologies waiting in the wings, and hybrids aren't quite out of the running yet.

Towing big things with a small boat

Towing little things with a big boat is pretty straightforward. There are plenty of nuances and details, of course; one sure way to spark a lengthy debate among cruising sailors is to ask about the best way to tow a dinghy. But, ultimately, towing something smaller than your own boat boils down to "tie it up, fiddle with the tow line, then drive normally".

Towing big things with a little boat is somewhat trickier, not to mention riskier. It is, nevertheless, important to be able to do it. You never know when you might have to press the dinghy into service to get a crippled mothership into harbour, or when you might need to help someone out in an emergency.

Back on the water

Well, Mother Nature, it took you long enough.

Spring is finally here, hopefully for good. Lake Ontario has thawed out, the birds are back, the fish are starting to spawn, and it's time to get back out on the water.

We usually make the first trip of the season a short shake-down cruise, rarely more than an hour or two, just to make sure everything's running properly. At this point the engine's been sitting unused for seven months, the remaining fuel's a bit older than that, and if something does decide to break we'd rather not be out of rowing distance from the dock.
