    In the next week or so, five adventurers will attempt to paddle a primitive hand-hewn canoe across 200 kilometers of ocean in hopes of revealing how humans originally populated East China Sea islands.

     

    The 40-hour trip, from Taiwan to Yonaguni, the westernmost of Japan’s Okinawa Islands, is the culmination of a 6-year effort to experimentally determine what kinds of craft Paleolithic peoples may have built and used, and how they navigated over long ocean voyages.

     

    Kaifu’s team—all seasoned ocean kayakers—will be paddling a log boat or dugout canoe of a type found in China and Japan dating back 8000 years.

     

    The team used simple stone axes, modeled on Paleolithic era archeological findings in Japan, to chop down a 1-meter-thick tree and then hew it into a 7-meter-long, 350-kilogram dugout.

     

    To emulate the ancients in other ways, the crew will not use modern navigational tools. Instead, the team includes a Maori man from New Zealand who can navigate by following the stars and judging winds and ocean swells.

  2. Cash-strapped Coastguard New Zealand believes lives will be put at risk if it is forced to pay a levy to the Government.




    The coastal search and rescue charity needs $20 million a year to keep its patrol vessels afloat. It receives 12.5 per cent of that from the Government and fund raises the rest. But as of 1 July it has a new bill in its in-tray.




    Coastguard NZ has been asked to pay the maritime levy, which it calculates will costs it another $20,000 a year.




    Maritime New Zealand said the charity was being asked to pay the annual fee as it is classified under the law as a 'commercial' operation not 'recreational' - the only two categories available.


     


    Historically the charge had been waived, but Maritime New Zealand director Keith Manch wants all organisations categorised 'commercial' to pay the levy, whether or not they are actually a business.


     


    As part of the recent funding review, consideration was given to whether that arrangement [the waiver] should be formalised.


     


    However, the Government decided that this would not happen

  3. hmmmm... presumably the load generator end, the boat, gets bigger spikes from the major jolts from gusts etc

     

    which gets attenuated down the chain through caternary? action 

     

    BUT

     

    if a situation occurred were the chain was bar-tight 

     

    then anchor end would up carry the load of the boat + chain into a tiny area of

     

    not good

    This was the complicated rescue of an Irish sailboat off the coast of A Coruña

    The five crew of the Loa Zour had to be thrown into the water to be hoisted

    The storm 'Miguel' generated about 250 incidents in Galicia, but the worst was at sea. An Irish sailboat was left adrift in orange alert, yesterday afternoon, and its five crew had to be assisted by Salvation troops in a difficult rescue.

     

    The rescue center of Fisterra activated the operation at 20:26 hours on Thursday, when it received the warning of the radio beacon of the sailboat 'Loa Zour', of 13 meters in length and Irish flag. It had been adrift about 85 miles northwest of A Coruña.

     

    Salvamento mobilized the plane 'Sasemar 102', based in Santiago, and the helicopter 'Helimer 401'. The rescue, according to sources of emergency service, was "very complicated" due to the sea conditions, very adverse. There was very thick sea with waves of 4 to 6 meters and winds of 65 knots, "which is equivalent to 120 km / h", according to clarifies the body of Development in social networks.

     

    The sailboat swayed a lot, which prevented the rescuer from going directly to the ship. He had to descend to the sea as close as possible to the sailboat. The five crew members had to jump one by one into the sea to be lifted to the helicopter.

     

    Those rescued did not need medical assistance. At 22:41 the helicopter managed to get them safe and at 23:20 the helicopter was back at its base in the Coruña airport of Alvedro.

     

    The crew of the 'Loa Zour' consisted of five men: one of 37 years, from Croatia, and four from Ireland: one of 47, two of 57 and one of 62 years.

  5. .es

     

    maybe spain and the notorious bay of biscay?

     

    yeah, the lack of a drogue or sea anchor made it pretty ugly for the lie-a-hull 

     

    esp. with the rags aloft

     

    but there's many a sea-state worse than that 

     

    down round here

     

    even dropping a bruce anchor would have helped

  6. 1.  hex number you guessed...the 15 digits UIN code

     

    The Hex ID or Unique Identity Number (UIN) is the unique code programmed into each 406 MHz distress beacon and is transmitted when the beacon is activated. 

     

    2. checksum probably = C/S..................... so 5 digits will be 10401

     

    From the 1st July 2012 all new 406 MHz distress beacons manufactured will also carry a Check Sum number.  

    This number is additional to the Hex ID or UIN.  The purpose of this number is to reduce the errors made by entering the wrong Hex ID or UIN into the beacon registration database when the beacon is registered.  The number is simply used to verify that the Hex ID or UIN has been entered correctly. 

    If the beacon has a check sum number this will normally be listed on the sticker directly after the Hex ID or UIN number. Note when registering your beacon if you are unable to locate a check sum number leave this section blank on the registration form.

     

    3. serial number probably = S/N.................so give 250-26785

  7. a reasonable battery test on smaller setups is to transmit, on a non-used vhf channel, and watch to see how much the battery voltage dips in the regulator display
