Iím ok on any day apart from Xmass day and New years Eve/Day.
Chris Iíve got a Garmin GPSmap 168 Sounder with PZ to Scillies charts, but it needs and external GPS antenna (currently on my RIB) and a 12v supply.
If you havenít got a GSP antenna Ill bring my it anyway as a backup for Royís, it fits the same power cable.
Iím going to do a passage plan, which will be a good exercise for me as Iím 1/2 through my Yacht master theory, assuming you have a compass on your RIB
If you havenít got a GPS antenna, with Royís permission it would make sense to use the handheld on your boat so we can chart the passage and separate the GSPís in case of emergency!
Well if anything it will give you all something to laugh at as it blows over the side
Camping could be interesting count me in Brrrr, but a hotel room sounds even better
