    Laundry

    Sorry no pic. I cut and paste the info from a website years ago when I first started dreaming of voyaging.

     

    My feeling is that any water tight container will do.

     

    But if you use hot water and shake it, it can generate quite a bit of pressure (I cracked a one litre EasyYo Yogurt screwtop plastic container that way when I was washing up in hot water).

    Haven't tried these, but my notes say try

     

    1. "Wonderwash pressure washing machines"

     

    2. in Oz one could buy a round plastic wheel device a tad larger than a football, which comes apart. Once half filled with water , suds and garments, then gets lobbed off the back of a moving yacht with a line secured through a central hole.
    Serrated ridges made it tumble according to boat speed and inside 10 minutes or so - one could pull it back on board and recover perfectly clean (but unrinsed) garments.

    3. I use a large bayonet locking lid/mouth waterproof duffel, fill with soap, laundry, water, add some hot, seal, blow up thru valve, rock back and forth on knee a few minutes, hang up
    and drain thru valve, remove and wring, repeat for rinse, use less than
    three gallons of water, does a weeks worth, takes 15 min, works as well as a
    ’sputnik’ type ( IE very well) but stows a lot better.

     

    4. We have a five gallon plastic bucket with a lid and one of those
    pink colored plumbers plungers (not black).  Or get a special plunger for handwashing
    We cut a hole to fit the handle in the center of the lid. Put the
    clothes and a small amount of detergent inside, fill the rest with
    water, put the lid on with the handle sticking through the hole and
    agitate for a few minutes.

     

    Now I'm beginning to think I would use a dry bag, fill it with water, soap clothes and shake.

     

    The real trick for me is the drying line. I learned on the Spirit of NZ that a line with small loops all the way along is brilliant. You make a cowhitch out of the loops and stick the corner of your clothes into the cowhitch - the wind pulls it tight. No pegs.

    Why cant we buy this Antifoul

    in MarineTalk

    Thought I'd look at the Altex AYB No.5 Antifouling NZ Safety Sheet. It didn't define TWA or STEL or TEEL but did tell me that mice who got too much exposure "produced signs of marked central nervous system (CNS) depression, including prostration after 2 hours, narcosis after 3 hours and some deaths". So if I see anyone lying down on the job ....

     

    Then again, from the Australian Safety Sheet - "Some thiocarbamates are structurally similar to disulfiram and may cause the characteristically unpleasant alcohol type reactions lasting for several hours"

     

    Altex ABY No. 5 Antifoul Composition
    copper(I) oxide    40 - 50%
    zinc oxide         10 - 20%
    n-butanol          10 - 20%
    xylene             10 - 20%
    rosin-colophony    1 - 10%
    thiram             1 - 10%

    etc

     

    For Altex No 5 you can leave it out of the water for as long as you like (Phew, one less thing to worry about)

    Dry Times (75 μm DFT / 25°C / 50% RH):
    To Recoat - Minimum 4 hours
    - Maximum Not critical
    To Launch - Minimum 8 hours
    - Maximum  Not critical

     

    But seriously, chewing gum on the water blasting has got me thinking. The info sheet says "With the correct preparation it can be applied over existing copper based antifouling". Preparation for a repaint is,

     

    "High pressure water clean (5,000 – 10,000 psi / 330 –
    660 bar) to remove all marine growth, hydrolysed antifouling, salts,
    loose paint and any other foreign matter."

     

    "OR: Low pressure water clean (3,000 psi / 200 bar minimum) to
    remove all marine growth, hydrolysed antifouling, salts, loose paint
    and any other foreign matter.
    AND - Wet sand the surface with 80 grit sandpaper to ensure total
    removal of any remaining contaminants, including residual
    hydrolysed antifouling and slime. Rinse thoroughly."

     

    "The cleaned surface, once dry should be free of any powdered
    antifouling residues and should be inspected for defects in the film.
    Existing anti-fouling must be secure and intact, and not excessively
    overbuilt."

     

    "Repairs to the coating system should be completed before the
    application of any subsequent coat of antifouling. To ensure good
    adhesion, any exposed primers / undercoats should be thoroughly
    sanded (p80 grit), dedusted & coated with the appropriate primer
    before application of any antifouling."

     

    "Thorough wet sanding is recommended at the waterline, as the wet
    / dry cycle and UV exposure can cause premature failure if brittle or
    crazy cracked coatings remain." So that is good info re my earlier question about getting marine growth up higher up the sides of Storm Fantasy now that it's in Okahu Bay.

    Life Jackets

    Lifejackets have undoubtedly saved the lives of three people on-board the vessel that capsized on the Manukau Bar earlier today.

    All three have made it to shore safely, we commend the skipper for logging a Bar Crossing Report which meant Coastguard Radio was able to raise the alarm when we didn't hear from the vessel to close their report and confirm that they had safely crossed the bar.

    It's inhumane NOT to have laws to protect the ignorant from themselves. What you are saying is let them die due to their own ignorance. That is not a proposition I can stomach.

     

    As to the reductio ad absurdum propositions, absurd doesn't advance your argument either.

     

    And on warm days of flat calm in sheltered waters with no danger of hoons, I'd prefer discretion to be exercised by the officers charged with enforcing the law, in much the same way that police have discretion in bringing charges or levying fines in many areas of our lives. There's nothing unworkable about that.

     

    Here's a brief list of laws off the top of my head which protect the ignorant: compulsory eduction, insurance law, consumer protection law, industrial standards law, unfair contracts law - the list goes on.

    Fish

    A. Yes

    B. Yes

    I've met families whose loved ones would be alive today if they had worn lifejackets. Have you ever mourned with a family who has lost a 7 year old and 5 year old in one boating "accident"? You should get out more Fish. Read the papers a bit more. Put your thinking cap on.

    Great post from GrantMc

    Fish says "If someone doesn't have the judgement to wear a life jacket when require, would they have the judgement to follow a law?"

    Fish, what's the difference between your question and a similar question by those opposing compulsory seat belts back in the day?

    Raising boot stripe - antifouled area

    in MarineTalk

    Posted

    Thanks for comments everyone. Yeah 220 mm is my guestimate sitting at home based on how high bits of black growth are reaching. It might be too much. I'd reasses when I get it out of the water. When I described the problem to someone else, he said 100 mm without any prompting.

    Raising boot stripe - antifouled area

    Now that my Easterly 30 is in Okahu Bay and not Weiti River it gets marine growth on the gelcoat higher up.

     

    I'm thinking I need to raise the anti-fouled area about 220 mm all around.

     

    Since I'll probably employ someone to help,  how many person hours per foot (say 60 feet for 2 sides of the boat) should it take to prepare the surface, sand back etc?

     

    Also if anyone can recommend good people who can help, please message me or post.
