Thread: Night Vision problem

    Question Night Vision problem

    Ausfishers I am hoping someone can help this problem I imagine has happened to others...
    Just taken delivery of a new boat - it has an enclosed hardtop - all round windows - no clears.
    At night, if there is any light in the boat at all, it is impossible to see out of the windscreen. Total blackout needed - even if someone in the cockpit gets a phone call that causes the phones' screen to light up it is difficult to see out. I imagine this problem has been around since windscreens!

    Has anyone got a suggestion apart from a total BLACK OUT?

    Thermal Imaging looks great, but too expensive (it's only a trailerboat)
    Infrared is cheap, but not sure it can do the job.

    It will be needed predominantly when cruising canals at night (boats and kayaks common)
    Rarely it may do a night run from the island (craypot floats the biggest obstacle)

    Can anyone share their experiences with the above technology, or any other ideas to help?

    Thermal camera and radar are the only options short of sticking your head out the window

    ...and before someone asks, the reason we don't want a total blackout? We can't see how many beers are left in the esky. (OK, and the fact that we need nav lights on too)

    Thanks Scottar I would stick my head out the window, but the window opening is too small (or my head is too big)

    2 big LED spotlights on the bow.

    Cheers Feral. I think spot lights are illegal on boats in enclosed waters. In WA at least. Spotties are an option for the open ocean run.

    Use dull red lights in the cab, these will not ruin your night vision. Nav Lights should have been placed out of the line of sight of the skipper.

    Re: Night Vision problem

    You have just discovered one of the major problems with hardtops. Very dim lighting on instruments and electronics is your only answer while underway, red does help. Have you considered a moonroof? I am an ex-commercial operator, spent nearly 3 decades operating out of a narrow rivermouth on the west coast with reef and swell to work around. Earlier boats I operated didn't have a flybridge. I drove with my head and shoulders out the hole standing on the seat steering with my foot. Sounds funny but works very well. Clear vision and you have the through-roof spotlight handle close to hand. Last boat before I gave the game away had a flybridge with all the lighting you could imagine--bloody luxury.
    The moonroof will also solve another big problem with hardtops--hot wheelhouse. Fitted hinged to the rear, they give very good airflow cracked open.

    a hand held infrared thermal camera does NOT work through the glass windscreen. all you will see is a reflection of yourself body heat in the windscreen. external thermal mounted outside fed back to a screen is different but much more $$$$$$$
    military style night vision ( ie green view) does work through the glass but you still need no deck light up and dull/red dash lighting

    spot lights mounted on hardtop roof do nothing really in ocean, up in close inside waters perhaps better yes or mounted on the bow nose also

    Re: Night Vision problem

    Using anything as "headlights" is useless, unless (as mentioned) when very close to a jetty or something, far better to have only mandatory and needed lights on, and just keep your eyes open, regardless of how much equipment you have to navigate with! In your case, I'm afraid you have a real problem of you can't stick your head up or out of a window, you will need to take extra care.

    Re: Night Vision problem

    What is the actual problem with being unable to see?
    Is it reflection on the screen from the interior lights?
    Is the screen tinted?
    Is it only you or do your deckys also Have problems?
    Had an optometrist check your eyes lately people with cataracts often have problems with night vision simple procedure to rectify.
    Cheers

    Re: Night Vision problem

    I was also thinking about optometrist but only because they can coat lenses on the inside to reduce reflections, there must be a similar solution for windscreens.

    Not uncommon with pleasure boats - especially shiny white fibreglass ones and if you have tinting it will only make it worse. You can reduce the effects by covering everything inside the cab with a matt finish black covering (carpet or paint) which will reduce the secondary reflections and hooding your nav gear so there is no direct path for the light to contact the screen but you will never fix it entirely and it will probably look pretty average. Rexaway is correct - thermal or IR systems do need to be externally mounted and feeding back to a display. The performance of these systems is pretty much directly related to their price tag as well.

    The best budget conscious (to a point) option would be a specialist short range radar for my money. Standard radar will struggle with things like kayaks and simply won't see a float. Something like the Navico 4G radars might but in rough water it will probably need to be "detuned" to the point it won't to avoid too much sea clutter. I would also be looking at a good quality spotlight.

    It's either that or make the necessary modifications to get your head out the window - to the boat or your head - your choice

    Last resort - get a hatch put in the lid above the skipper's possy.

    had the same problem with my soft top - I was able to get zipperred sections put in at the front.
