    Sextant lubrication and protection
    From: Doug Royer
    Date: 2004 Aug 2, 16:00 -0700

    I've been following the discussions with interest on a belated basis.I've
    been quite busy since the new security regs came into being in July.
    I took a post instructing and certifying mariners in STCW.Also the theory
    and hands-on training in the new shipboard securuty procedures for U.S.M.M.
    To belatedly put in my $0.02 on a few subjects:
    1. I found one of the very best lubricants/film protectants to use on a
    sextant subjected to use at sea is a product known as NYOIL.
    It's not that expensive,relative to the cost of a sextant,around $9.00 for
    an 8 oz. bottle.That 1 bottle will last years.It has about the same
    charactoristics as the old Sperm Whale oil except the smell.If this is
    unavailable in your area a high quality Jajoba oil should be.This natural
    oil has the same charactoristics as the shark liver lubricants used in the
    2. I wrote of this in the past.Perhaps some of you missed it: protect your
    sextant mirrors before you go to sea by applying a product known in the U.S.
    as RAINX to both surfaces of the Horizon mirror,the Index mirror and glass
    surfaces of the optics.It really retards any corrosion of the glass surfaces
    in the event you are negligent in the maintanance of your sextant for what
    ever reason.
    3. Something Joel wrote about 7/8 size(yatch)sextants vs full
    size(metal)sextants I'd also like to comment on:I've used full size sextants
    exclusively in my career.I've never used a 7/8 size sextant on either a
    small or large vessel.I do know I,personaly,like the heft of a full size
    metal sextant over a full size plastic sextant for the simple reason I'm
    used to useing one.
    Now take the following with a grain of salt as I'm not a small boat driver:
    It was taught to me and practiced by myself and other professionals to
    discipline one's self during sighting procedures to take 1 cut of a body and
    move on to the next one,get it done and move on to the next duty.A
    proficiant mariner should be able to accomplish this with practice.That said
    most of you know my background in larger vessels and my lack of time on
    As for Joel's comment on heavier rifles vs lighter rifles and the inherant
    ease of holding a heavier rifle on target over a lighter rifle it is
    true.One learns to use a heavier rifle's weight to advantage and one doesn't
    get beat up by recoil as much as with a lighter rifle useing the same
    rounds.I'll take an M1A1(M-14) over an M-4 carbine(M-16 variant)any day
    because of the ease of holding it on target.
    I feel the same about sextants.
    Take care all.
