There are two versions of that question. One is about Looping solo. The other is about whoever isn't usually at the helm — and the Coast Guard has a name for it.
The US Coast Guard Auxiliary teaches a four-hour course called Suddenly In Command. It's aimed at people who are not normally at the helm and who may find themselves running the boat because the skipper is ill, injured, or has gone overboard. It covers basic handling and docking, what equipment is aboard and where, the rules of the road, communications — and, tellingly, how to start the engine.
The fact that the course exists tells you how ordinary the scenario is. On a trip that averages close to two years from departure to finish, the odds that the usual skipper is always available are not good.
🔴 So the useful question isn't "could I do this alone?" It's "could the one of us who doesn't normally drive bring her in alone?" Every feature below answers that question and the solo one at the same time — and the second question is the one almost nobody has been asked.
The Welland Canal requires three people aboard — one operator and two line handlers — for all upbound pleasure craft transiting Locks 1 to 7. It's because of the water turbulence. The Montreal-to-Lake-Ontario section requires a minimum of two.
This surprises almost everyone, including people who've been planning for years.
⚠️ It's also avoidable. The Welland is only on one of the three routes from New York into Canada — the one that runs the Erie west to Lake Erie, and needs the lowest air draft of the three at 15'0". Take the Oswego route or the Triangle and you never see it. If you do go that way, AGLCA's own advice is to contact local marinas for extra hands, or use the telephone at the pleasure-craft dock.
Six owners, independently, named the same two things.
A continuous side-deck handrail, bow to stern. Alone on deck with a line in one hand, a rail is what you hold with the other. Owners are blunt about it: "no rails for single handing is a deal killer" and "it is not a convenience — it is a requirement with one person."
A side door at the helm. It lets one person step out, take a line, and get back to the controls without crossing the boat. From a Looper who did the whole Trent-Severn alone: "I would not try it without side door."
🔴 Neither appears on a listing. No spec sheet tells you whether the rail runs all the way aft, or whether the helm door is a door or a window.
On most western-river locks, one midship cleat is all you need — one wrap on a floating bollard, no tending, nobody moving around on deck mid-lock. What decides whether that works is where the cleat sits. A Gold Looper put it plainly: "it was right outside the pilothouse door. Never had to leave the helm to lock."
The Erie is a different problem. Lines hang down the wall and you catch them with a boat hook — which wants a second pair of hands regardless of how the boat is fitted.
A lower helm you'd actually use. Having one isn't the same as having one worth using. Plenty of boats have an inside station with poor visibility and no heat or air, so the owner runs from the flybridge anyway — which is a long way from a line.
An autopilot. Owners describe it as the thing that turns a long day into a manageable one, and on some hulls it's what makes a known handling trait tolerable. Single-handed, it's closer to essential than to a convenience.
Whoever isn't usually at the helm should be able to answer these on the boat you're considering:
If the answer to any of those is no, that's not a reason to walk away from the boat. It's a reason to take the course — and to notice whether the boat's layout makes those answers easy or hard, because that part you can't fix later.
Owners and Gold Loopers who have run the route, several of them alone; AGLCA's published route guidance for the Welland requirement; and the US Coast Guard Auxiliary's Suddenly In Command course for the framing — cgaux.org, roughly four hours, taught by certified Auxiliary instructors in person or online. Check with your local flotilla for dates and cost. We haven't run it single-handed ourselves — this is what the people who have say about it.
If we've got something wrong, tell us and we'll fix it — support@caniloop.net. A correction from someone who has actually run it is worth more than anything we can write.
