Into the night

I've always been scared of night passages for fear of being caught by a pot. To overcome this, I've just fitted a FLIR thermal camera to see pot markers at 1km. I have yet to test this but I've been asked by a few people to take pics and report - which I will do.

Piers, I'm curious. Why would a thermal imaging camera show a pot marker, which surely wouln't have a heat source?

Hi Andrew. The M series FLIR camera I have had mounted on Play d'eau can sense a temp difference of 0.2C. I've been assuerd by FLIR's Distribution Manager that a pot marker out of the water will be at a diff temp and will therefore show up. He'd better be right!

FLIRs promotional videos are good and on their website here, http://www.flir.com/cs/emea/en/view/?id=45887.

As I said, I aim to report on the FLIR's ability.
 
As others have said, boating is a very different experience at night. Can be quite disorientating until you get your 'night vision' and judgement of distance is difficult. Makes you understand the inportance of the different light phasing on the channel markers, that's if they're lit at all!

lobster pots are definitely a big concern though!

If he's wrrong you might find the buoys anyway!
 
Done it a few times over the years, I cruise all winter on those lovely calm days and I tend to stay out longer than planned, returning to my berth in the dark.

I do tend to slow right down because of the fear of catching one of those pot markers. But other than that I don't mind it and not had any problems.

I have in the past done a few night dives, so diving and boating in the dark is quite an experience, marine life well comes to life.

The only mistake I made many years ago back in the 90s was on the early GPS (before chart plotters), I marked a way point as my entry to Helford river during the day, but only to find after a dive later at night that the GPS didn't have a signal when I marked the waypoint, basically took me the wrong direction, so it was a slow trip back following the coast line.

0.2C sounds impressive.
I shall be interested to see how you get on with it, especially with regard to pot markers.

Came back overnight from IOM with a friend a few years ago, would have been handy if the chart table light worked and even handier if the compass light worked! Interesting though, quite a different perspective to during the day.
Crewed on a tug many years ago, radar does help an awful lot although it seems a bit strange initially to have your head buried in it.

As autumn draws on, more of us will be having views like this. It's still on my 'to do' list, but how many of you venture out in the dark of night?

me - often. Definitely more than 10 times a year.

I have a button to kill all the instrument lighting, one press for a quick look with 1 eye. The plotter screen is off as it's too bright even on minimum. Radar only is OK, or cover it up.

On my S37 the top cover had to be in place or the steaming light illuminated the whole cockpit. On my new to me 390 the light is on the front of the radar stump and is going to be a nightmare. I will have to helm from inside I think.

So many boats make night work too difficult. Take time to get your boat sorted by eliminating light pollution.

Once you've got your night vision you really can see in the dark. Your situational awareness comes back as that plotter thing is off.

And it's fun.

On all my boats i needed a plate under the toplight to prevent it from "light-pollution" - its available in black plastic in most boatshops, and as they dont cost a lot, its unbeleivable that boats are delivered with approved lights, but such a small piece is saved .. .

Thanks...... I have to say that I felt a bit of a whimp last night until the wind picked up about 3am :) Turned over and went back to sleep with a smug smile on my face.

It's always a problem trying to do this journey at this time of year and I got caught out several years ago and I dont want to suffer that experience again.

As I said before, I use to enjoy night cruising but these days it's more trouble than it's worth.
