"They can't see you" is my default assumption. COLREGS might help my widow get a better settlement, but I will get out of the way of shipping unless I have positive proof they've seen ME. That's the same approach I take, just like on a bicycle or motorcycle. Where I usually encounter them (Lake Ontario approaches to the St. Lawrence) they don't have too many maneuvering options anyway. Ryk |

Nobody in the commercial fleet runs at 32-36 knots, especially not tankers! The very fastest container ships and LNG carriers are around 25-27 knots. Cruise ships are slower, around 22-23 knots top speed and most tankers are slower still. The exception would have to be the SL-7 Fast Sealift ships which did 33 knots on trials. I am not sure where you operate, but it's worth noting that there are a number of situations where one encounters commercial vessels that routinely operate at greater than 40 knots. I have been sailing Bay of Fundy for quite a few years now. This is an area where fog is common, and also an area where the "cat" ferries transit from the US over to Nova Scotia. These beasts are over 300 feet long and have a cruising speed of near (or perhaps over) 50 knots. Several people have been killed by them in the past few years. Indeed, I had the devil of a time getting the attention of the Bar Harbor - Yarmouth ferry in high visibility conditions in one particular instance.

I can't say how fast ships travel in general but acording to my shipping
papers the sort of average container ship carrying my latest shipment of anchors left the dock at Le Harve, France at 13:15 UTC on February 10 and tied up at Wando Terminal Charleston, SC on February 16 at 11:21 UTC. That is 5 days 22 hours and 6 minutes or about 142 hours. Great circle route between LeHarve and Charleston is 3,820 nautical miles so the average speed was 26.9 knots. That assumes that they took a short cut through the desert across the NW corner of Africa and manouvered at full speed in port. :-) However, from Wando terminal to the pickup dock in Savannah, a distance of 111 statuate miles took 6 days and 4 hours or 148 hours for an average speed of 0.75 MPH. -- Glenn Ashmore I'm building a 45' cutter in strip/composite.

"at least an hour will pass from when I see a contact on the horizon to when it will hit me". My point is that ships at sea operate at a wide variety of speeds, even in excess of 30+ knots, and as a cruiser you need to be aware of this. As for "high speed" ships out there, I think you guys are off on this. All the newer ships are being built to operate at 30 knots or greater. There are a number of "fast" container and oil carrier ships in the works, and shipbuilders are starting to deliver "fast" ferries that will operate at 40+ knots. And it won't stop there, I've read that the designers have plans for ships that will operate at 50 to 60 knots. Fascinating. I'd like to learn more - can you point me at any web sites?

Ryk Agreed, they were worth keeping an eye on. However, Naval vessels have far more crew than commercial vessels, consequently there is usually, unless the practice has changed, several physical look-out plus the radar is manned 24hrs. when they are at sea, so I wouldn't be too concerned about them not seeing me, but I'd still keep out of their way.g I remember once in the Med. when we were doing anti-submarine exercises and steamed all night in black-out conditions, no lights anywhere.

Big difference between "high speed ferries" and ships.

Armond,
Those are "high speed ferries", not ships. They involve a whole different set of operating parameters than ships, including stopping distance. In dealing with them and discussing them, you need to realize and understand that comparing them to normal commercial traffic is comparing "apples to oranges"....., same applies to standard tugs and Z-drive or Voight Schneider. otn "Armond Perretta" wrote in message I am not sure where you operate, but it's worth noting that there are a number of situations where one encounters commercial vessels that routinely operate at greater than 40 knots.
