AIS as a substitute for radar?

There have be numberous cases where AIS transmissions are faulty or indeed none transmitted on ocean ships where there is a requirement to carry ONE

Are there recent reports of this happening, or was this during the early days when AIS was first being introduced? Anyone know what the penalties are for a ship not transmitting AIS?

There have been previous articles in the RIN Journal that while fitting AIS is compulsory, there are lesser standards for level of training and location of AIS sets, and integration with other nav equipment.

As a rule a failed unit ought to fixed or replaced at next port but alas not always possible or practical.

They can also be switched off manually or the settings changed manually.

i once saw a p&o cruise ship whos AIS said it was at anchor off Marbella but was steaming along by Gib at 20+Knots.

"so i'll have the time, speed and manoueverability to avoid another boat, even if I see it late."

So what do you do if the fogs so thick you cannt see the front of your boat - then? its happened to me many times the only answer is radar

Well first off we'd only go with a good weather forecast, no fog expected, and clear skies leaving home. In my experience the fog that drops in the channel when its sunny on the coast, tends to be the more patchy stuff, where you go in and out of the fog, and in such circumstances I don't think i've had visibility (of a shadowy outline) less than 100m.

If it turned into a real pea souper, we'd always have the option of turning for home.

AIS is a great addition, I love mine, went the Digital Yachts path myself, great unit.
