    Halyard size

    in TechTalk

    Posted

    One thing you want to do is add as little friction as you can to the masthead halyard, especially from the fractional point to the top - thats often when the gennaker just about sets, with the foot in the water and you need the guys to get it that last metre as quick as you can - often the difference between a glamour set, or a nice trawl and a visit to the sailmakers. 
    So the bungy might add just enough friction to cause issues

    Halyard size

    Smoke wagon has exactly what you are describing without the bungy. Works really well and we havent found a need to have the snubber tight when not in use (i.e. dont need the bungy.
    One masthead halyard that snubbs down to a fractional.

    Ours just goes in a V Cleat at the base of the mast i think - will go for a stroll next door to where boat is stored later this morning out and have a look - thats the bow girls territory not mine so cant remember ;-)

    window replacement

    in TechTalk

    Posted

    Have just finished replacing all windows in my launch (Vindex 350)- front we did glass, side we did with Acrylic. (Have also previously done them on Mercenary which are still hanging in some 10 years later!)

    Used Dow corning 795 - the stuff is awesome, i wouldnt use anything else having seen others struggle to key, or to handle the UV and heat.

    Protest question

    in RaceTalk

    Posted

    61.1. Informing the Protestee
     
    1. A boat intending to protest shall inform the other boat at the first reasonable opportunity. When her protest will concern an incident in the racing area that she was involved in or saw, she shall hail ‘Protest’ and conspicuously display a red flag at the first reasonable opportunity for each. She shall display the flag until she is no longer racing. However,
      1. if the other boat is beyond hailing distance, the protesting boat need not hail but she shall inform the other boat at the first reasonable opportunity;
      2. if the hull length of the protesting boat is less than 6 metres, she need not display a red flag;
      3. if the incident was an error by the other boat in sailing the course, she need not hail or display a red flag but she shall inform the other boat either before or at the first reasonable opportunity after the other boat finishes;
      4. if as a result of the incident a member of either crew is in danger, or there is injury or serious damage that is obvious to the boat intending to protest, the requirements of this rule do not apply to her, but she shall attempt to inform the other boat within the time limit of rule 61.3.

        Note 61.1.A - 4
        But you would need to justify serious damage or injury

    Lifting Engine with Boom

    in TechTalk

    Posted

    Yup did the Volvo 18hp out of the old Y88 the same way, and put the new 30hp in also - so boom can handle it as they say.

    Just tie the halyard onto the boom at the same point that you are lifting from so there is no bending moment in the boom.

    Chainblock makes it way easier so that you can do micro increments up and down and then align things. but ifnot a mate with a winch handle does the same :-)

    Anchor chain

    in TechTalk

    Posted

    Having dived on my anchor a few times over summer - anchored in 5 metres or less of water with plenty of chain out - not often have i actually ever seen the anchor taking the load apart from when rafted up and its on a funny angle (One of many anchors).
    Other than that normally anchor is side ways and chain weight on the ground and catenary is taking the load.
    Vindex 350 with 8mm chain and a 50lb manson surpreme (i like to sleep at night and also raft up often).

    Witch Doctor was rebuilt by Chris Mc Master (ex Doyles) on his front lawn in Howick. Had to flatten his wife's rose garden to get it in :razz:

     

    That would have been the build of Frenzy if it was in Howick. Marine Parade...

     

    Witch Doctor was done by Chris McMaster in the driveway on Point View Drive. I recall as a kid watching it come into Halfmoon bay on a barge, a second barge followed with the keel.

    Chris had a boatbuilder on it full time and was done properly. Has done a lot of miles since then including offshore work. - Dad raced on it halfway to Fiji only to turn around during the Coup in 2000.

    Icebox tips

    the 3 way fridges are really only 2 way - 240v or Gas.

    running the small 30litre one i had on Mercenary on 12volt made luke warm beer and drew about 5 amps.

    If you are thinking of using battery / 12v then go a proper compressor 12volt fridge / waeco unit not an LPG / Thermotropic unit?

    We left halfmoon bay in a rush one friday afternoon last year -wife loaded the boat up nicely and i went straight to the boat from work so in dress pants, shoes and shirt - kicked off the shoes and drove boat out to Rakino to get there before it got dark - anchored and enjoyed a beer (which the wife had even loaded in the fridge).

     

    Come bed time i stroll downstairs into the cabin and look for my clothes bag... Hmmmm

    Wife had packed hers, and sons (8) not mine, i asked and she cracked up laughing as she realised that she had unloaded the boot but left my bag in the back seat of the car...

     

    Saturday morning quick trip back to marina to get some clothes for the long weekend!

    Solar Panel Fun - Is it dead or is it alive...

    Haha they were in the sun - hence one of them works one doesnt.

     

    @CrazyHorse - not really in that when you measure the Open Circuit voltage the current isnt at 5amps. Likewise when you measure the short circuit current the voltage drops a little. you cant measure the two together and get that.

     

    @StrayCat - Panels are probably 5 years old but they were bought by previous owner of boat so not sure where from etc. there is diodes in the connector box on the back of the panel itself.
