Thanks all, some very interesting sites. But, as you say, not what I was hoping for. There are a strong series of currents running North and West from Madagascar and North up the coast of Mozambique, Tanzania and Kenya, up to 4 or 5 knots at some times in some places, with back eddies. So it...

I'm looking for a tool to give details of ocean surface currents. I'm sure the data is out there and available for accurate prediction over reasonable timescales of the location, direction, speed of currents, but I cannot find it with the resolution I would like. I'm thinking particularly about...

And remember that in a serious emergency, it is invariably debris clogging the pump's inlet that is the limiting factor, rather than the capacity of the pump itself. No matter how immaculate you think your bilges are.

Thanks both, very helpful responses.

Would you expect a 'typical' sat-phone to receive a normal SMS from a mobile phone? I'm currently in Addis Ababa trying to communicate with someone in the middle of the Adriatic. He has a sat-phone, I have a roaming mobile. Calls are impossible, sometimes he gets through to me but the quality...

If so, I would be grateful for a PM? Thanks

So shoot me. Sheesh You are the 2nd person to complain that I am the 4th person.

As others say, as long as you know roughly where you are and the amount of tide, depth can very often provide pinpoint accuracy. On two occasions when I have been doing blind nav for fun, the crew on deck had to alter course without telling me to prevent us hitting the buoy I was going for.

I would absolutely not do that. But I have in the past soldered after crimping, that can only help electrically and allows a proper hard metal contact in the crimp. I then back that up with very good physical support - typically an adhesive-lined heatshrink - because we are constantly told that...

Thanks, any pointers to sources of this stuff would be appreciated.

I fiddled with it - no improvement. But perhaps I have been unlucky, I will try for a similar one.

Can anyone advise on a decent crimp tool? I bought one of these a while ago It worked well for a while, but seemed to rapidly loose its gap settings and no amount of fiddling has got it right. I now use a very crude device like this: Which sort of works, but it is awkward to get the crimp...

The radio is extremely unlikely to have been damaged. Attempting to clean the connector is a waste of time. If you are convinced the coax is OK then cut back to clean wire and remake the connection. If you can't do this because there is not enough wire then I would certainly replace the lot, and...
