    Interesting (and brief) notice on the Gunboat Corp. website yesterday.
    Looks like GB6801 Highland Fling (ex-Condor) was relaunched recently. One of the subtle points in the update was: "... with super smooth teflon antifouling ..."
    I've never heard of using teflon as a coating to prevent marine growth. Anyone else around these parts?

    I'm sure it is super slippery (when wet), lightweight and pricey to boot!!

    Cheers - Ogre

    Been used on military vessels for many years. Expensive and finicky to apply, works much, much better underway, high upkeep, easily damaged. It has it's uses though.

    Here is some ad copy...I have no connection with this company and suggest you do your own research ... First decent thing that came up googling "military teflon antifouling"

    Thanks Jehardiman.
    Even after all my military time I have learned something new then.....
    You had me at 'high upkeep' though, as I do not need another component of that nature on my cat.

    Regards - Ogre

    By high upkeep, I mean you need to monitor it and keep it clean. It can't be left sitting in still water for long periods or it will begin to foul. It really works better on vessels that are almost always underway.

    VC17M antifouling has been around for years.. Works well on motorboats, fast sailing boats and sailing boats in low fouling areas.
    Reports I've seen is, it doesn't work so well on sailing boats in high fouling areas that remain parked all week..
    The high maintenance, is an occasional wipe down, but although a hard coating it's easily damaged if you were to park a cat on the beach..

    I've a tin of VC17M in the shed ready to apply soon.. My boat is in a low fouling area, I can crane it out when I want and it's small..
