Does this screw look like it can produce much thrust? I took this picture after I spent about three minutes chipping away at the marine growth which had accumulated in about two months. (It looked like a Christmas wreath before. I’m sorry I didn’t take a picture of that.)
The vessel in question, the Green Lantern, had spent about two months in Long Island Sound, just sitting at her mooring. Her engine was run weekly. However, that engine was never engaged in gear and run up against the mooring. As a result, all aboard–experienced professionals, the four of us, with more than 60 man-years worth of experience–were under the impression that we were going to be able to control the boat under power. We had boarded with the aim of taking her to Port Jefferson to lay her up for the winter. It was a beautiful October day. We came stocked with food, snacks and a case of readytogoitis.
We set up the boat and got under weigh. Just after we left the mooring, we caught a gust on our port side which sent us skidding leeward toward a string of small boats, one of which was particularly expensive looking.
Close quarters manoeuvring is always something to take extra care on, so our skipper altered course to port and increased speed to increase the clearance room. The engine took on a distinctly higher thrash note and our course and speed did not change appreciably. We continued skidding to leeward and that particularly expensive yacht turned out to be a Tartan on closer examination. Three boat lengths.
Denial is a funny thing. If you’ve altered course by half a wheel and given the engine 50% throttle and nothing’s changing, it’s a good bet that nothing’s going to change if you add even more power and turn the wheel even more.
We continued to threaten the leeward boats with a solid carom, and distance was down to 2 boat lengths. It was time to get some auxiliary sail up–or, in our roller furler’s case, out.
What a mess. So much of a mess that I do not remember the exact sequence of events. Distance off that other boat decayed to less than one boat length, totally out of control, before we were able to get some way on and sail out of there. That day I also learned never to pick up a fiberglass mooring buoy pole with bare hands, because the gel coat is broken down and you’ll get rewarded with a handful of splinters.
What contributed to this event? The NTSB investigators who look at major accidents often refer to an “accident chain” in their reports. The idea is that it’s usually not one big thing that causes an accident—say, inadvertently triggering the “Keel Fall Off” button—but a series of things. And some of these “things” can be attitudes rather than actions or omissions.
Here’s my own brief–the other parties involved can weigh in in the Comments section:
1. Failure of the crew to establish and participate in an adequate culture of command. This is probably the hardest thing for recreational sailors, which that day we were. We stepped aboard as friends and forgot that someone has to be in charge. We set up the boat properly and did our checks, but we did them willy-nilly, without deliberation or instruction. Failure to operate in a culture of command means other things can get forgotten and the crew isn’t prepared for eventualities.
2. Failure of the crew to adequately inspect the vessel. We did bilge checks. We checked fuel filters, sea cocks, ran up the engine, attached halliards and exercised the steering gear. We did not, however, run the engine in reverse to ensure that (a) the propeller was still attached, (b) the transmission was in working order and (c) that the propeller was providing adequate thrust.
In fact, the crew deliberated at length after the event as to whether the prop had fallen off.
3. (Contributing) The crew succumbed to getthereitis. We were excited to be there and that contributed to proximal causes (1) and (2).
We still talk about this today. Get out there enough and you’ll have your own sea stories. I’ve spent 15 years on the water, making mistakes during every one of them. Just make sure that yours are original, okay? So, always run up your engine against the mooring or dock to make sure everything’s in working order prior to departure.
See you on the water,
