Frankly, though, I have had far closer encounters with dopey fellow recreational sailors, powerboaters and jetskiers than I have with commercial maritime traffic. I have had 35-40 foot sailboats under main and motor cross my path obviously under autopilot in Lake Ontario with no one at the helm or visible. I gave one such "near miss" two miles offshore a blast with the horn (I was under sail alone) and saw a bed-headed sailor with a mug of what I assume was coffee appear in his cockpit, peering owlishly about as I sailed off, having missed him by about three boat lengths. Coming back south to Lake Ontario was a real eye opener towards the end of this season. The recreational traffic was so much denser in the Niagara to Toronto area. I had got used to scanning the horizon, seeing nothing, and figuring I had 10 or 15 minutes to myself. The freighters were much easier to deal with. There weren't as many of them. They didn't change course capriciously. Their lights were good. It was still challenging to keep comfortably out of their way in tight places like the St Clair River, especially at night. Some people just don't get it. He probably thought his chartplotter would shriek if he got near another vessel. There's an advantage to starting out with very limited instruments Ryk |

Ryk,
I'm checking your arithmetic. Let's say the horizon is 4M away from the helm of an average recreational vessel, so two such vessels in good visibility might have sight of one another at 8M (but would look very small and not "leap out" visually). If one is a sailboat doing 5 kt, it will take quite a while to cover that distance. But if the other is a planing powerboat doing 30 kt, it might be there in roughly 15 minutes. Two power boats at that speed would be "together" in half that time. So, you might be about right. Does that mean you don't keep a constant watch? ==== Charles T.

Thanks for fleshing that out.
Single or short-handed boating does, of course, require some compromises. I don't find anything in the ColRegs which exempts any boater from keeping a constant watch, and yet there are situations - such as sleeping while anchored - in which the authorities seem to recognize implicitly that it's a safe (enough) and accepted practise. Has that policy ever given you any close calls? ==== Charles T. Low www.boatdocking.com ==== "Ryk" wrote in message ... Am I constantly scanning the horizon?

Although I have occasionally been caught by surprise while (supposedly) keeping a constant watch, usually by somebody overtaking, or sneaking into the blind spot under the genoa. I think I may be more concious of checking the full 360 when I know I've had my attention elsewhere for a little while. Ryk |

I think I may be more concious of checking the full 360 when I know I've had my attention elsewhere for a little while. Same here. I cruise an elderly cruiser-racer, but crew with club racers (good way to improve your all-around skills, IMO), and my skipper of a few seasons back could visualize dynamically whether boats would collide or scrape past. So he would look, calculate and yell "Hold your course" when boats would cross on opposite tacks. Other racers knew that in this respect, he was pretty good, and so boats would frequently cross with three or less feet between them, and with neither side correcting on the helm. The vagaries of wind can create some odd scenes even while cruising, however. This October, we cruised down Lake Ontario and saw (predictably) fewer boats than fingers, so to speak. And yet I saw sight of one fellow in a 26 foot sloop, miles off and (slowly) closing. I kept taking bearings and remarked that 'this guy could hit us...in 20 minutes or so". This was four or five miles offshore, with ZERO traffic. Sure enough, my fellow frostbiter crossed my bow with about one and a half boatlengths to spare, and the customary non-chalant nod and lifting of a finger off the wheel in salute that passes for a wave hear. He wasn't aiming for me, or changing his course for a look-see, because I had been watching him for ages and the wind and his helming were steady. We just happened to intersect each others' proper course. R. |

I have a small Furuno on my boat and it picks up everything. On a calm
day I track seagulls and logs. Its only when the sea surface is really disturbed (25+knots and lots of fetch that the radar starts missing small boats. Having driven large ships, I would say that if they are watching their radar, they will see you even in a small fiberglass boat unless the sea state or weather is such that clutter is a problem |

Gary...does your Furuno unit have alarms
or notifications of "bogies"... ? |
