Re: Point of order
I think many of us are guilty of too much reliance on technology.
I have always fitted a Raymarine combined radar/chartplotter.
On our first X channel about 9 years ago we were approaching the needles in the dark and the wind had got up to about 30kts and we were having a roller coaster ride when I suddenly spotted a light beside us. I checked the radar and realised that when I actually looked for it I could see possibly a small boat but otherwise this some 40' yacht was lost in the clutter.
Since then I always assume we may not be "radar visible" to others.
My second big lesson was relying on the charplotter. I have in the past relied on it -including going round the SW inshore side of Jersey. At times it felt that we could reach out and touch the rocks either side of us but I was confident as we had the chartplotter. 2 years ago I went up the river to Pontrieux and while I could see the buoys and the deeper part of the river the Navionics Platenium card had us firmly going along inland by about 300m in the solid granite cliffs. I dread to think back to the times I relied mostly on that chartplotter. I checked all the setting but concluded that the card has the river wrongly plotted to one side.
I now rely on good examination of the charts and passage plan with waypoints already feed into my handheld GPS for any couse change position before any tricky passages and Mk 1 eyeball during the passage.
Radar and chartplotters can be a help but they can also give you a false sense of security.
