The pilot boat's alongside Islay Trader.

Meanwhile the Salcombe lifeboat seems to be heading to pass the Lizard, and the Iron Duke is still on a steady course towards Falmouth...

Both the coaster and the pilot boat have left Porthoustock - Islay Trader is heading east to Alderney, and LKM north to Falmouth.

But the LB is heading SW, out to the middle of nowhere!

The Iron Duke has decided it doesn't fancy Falmouth, and is heading back ENE for Plymouth again - or is it just playing war games?

While I was watching the tennis, I lost the Salcombe LB! Shocked

It had given the Lizard a wide berth, but was last seen heading towards Lands End. Now it's not apparently on the AIS, and the search box can't find it either.

Islay Trader, however is well south of Plymouth, heading for Alderney.

She's now on the edge of the traffic separation scheme around the Channel Islands. First she has to cross the west bound lane, and then the east-bound lane.

The traffic is pretty heavy both ways, mostly cargo ships and tankers, but with other stuff mixed in. What a contrast with Portoustock, and the sparse traffic in Falmouth Bay!

There's a (slightly grammatically garbled) description of AIS here:
http://en.wikipedia.org/wiki/Automatic_Identification_System

AIS is still fairly new, but watching Islay Trader crossing the shipping lanes makes me realise how much better it is with AIS. This is because it gives you the speed of other vessels, making it much easier to judge whether it's safer to pass astern or ahead of a crossing vessel. With just the Mk.1 eyeball, you'd have some indication of her course, but that's all. (Radar helped, but most of my time at sea was without benefit of radar.)

Islay Trader is in the middle of the west-going lane now. There's not very much wind, and it's still summer twilight, so she should see the ships and their navigation lights, which is handy. Plus she'll have radar and AIS - what could possibly go wrong!!

Islay Trader has passed clear ahead of a west-bound gas tanker, and has now cleared the ships in the west-bound lane.

The east-bound lane is relatively quiet at present - quite a bunch of ships went by a bit earlier, though.

Islay Trader is just stooging about, a mile north of Alderney now - perhaps her berth is not yet clear, or she needs a higher tide. (It's actually low water there now, next high at 1305 BST.)

Another LB on the move - heading SW past St Ives is 16-04, the Padstow LB. Either on exercise (but a long way from home), or en route for refit or repairs.

I thought marinetraffic.com wasn't refreshing properly when I saw TWO lifeboats on screen - but looking more carefully, the Sennen Cove LB, 16-14, has come out to join the Padstow boat! (They often excercise on Sundays.)

And the Sennen boat is pootling around near home, while the other speeds on to the SE.

As the Padstow boat approaches the Lizard, the Penlee boat, 17-36, is just south of Mousehole, presumably on exercise.

The Penlee boat seems to be returning to station (in Newlyn). The Sennen boat too is heading for home.

But the Padstow boat has passed the Lizard and is heading east - to Poole, perhaps, RNLI HQ.

The Padstow boat could be heading for Salcombe...

Elsewhere, my German friends are under way again in the Firth of Clyde, and Islay Trader is in Braye Harbour, Alderney. Closer to home, the Falmouth LB is heading up the Carrick Roads.

The Padstow LB has passed Salcombe, and is now passing Start Point.

Like other Tamar class RNLI LBs, she has a range of 250 nmi, and a speed of 25 knots, which is about what she's been doing all the way so far.

I just learned something new about marinetraffic.com - it shows helicopters as well as vessels on the sea! I spotted it off Bournemouth - I thought 139 kn was a bit fast for a boat!

It could be it only shows SAR copters, but we have plenty of those in Cornwall. Maybe it only activates during SAR activity. It's gone now.
