    I may be wrong but I understand the foils on the IMOCA boats are Dali profile intended to provide lift and resist leeway, still depending on a canting keel for stability. The AC boats are interesting, and the AC35 was great to watch, but I don’t relate to the AC boats zooming past me in the Hauraki Gulf as anything related to what I’m doing save for the fact that they are using sails.

     

     

    A few of the new boats have different foils to the 'old' Dali foils this time, more of a C shape which is more forgiving.  They talk about it in one of the vids in this link.

    Interesting to see Sam Davies looks like she sailed right past Jeremie Boyou on Charal which was one of the pre race favs.

    Does anyone know what that exclusion zone is out of the Galician coast?

    Thailand Drag Boats

    ah!  Thats sooo good!  The casually doing 75 to 80mph in a mahogany canoe with a diesel outboard strapped to it !

    I travelled in Thailand in 1989 coming back from the UK. In those days Ko Samui was a sleepy little island very few people went to.  We caught a longtail out across the bay from the mainland to the island.  Great fun.  In those days they were powered by Nissan 4 or 6 cylinder SD diesels.  I don't think we had any safety gear apart from jandals...

    Was just thinking exactly the same thing, absolute gold!  500hp with a direct hookup to a propellor, what more could you want! 

    I drove one years ago when I was there, the owner wasn't that keen on handing over the reins but I told him I'd driven boats before and he let me have a go.  I was surprised how hard it was, they're a bloody handful with all that torque and I found I had to really concentrate on what I was doing.  And it certainly wasn't 500hp behind me.

    Looks like good idea to check what payments you have going on on Paypal. I can get Windy free. What advantage when you pay?

    on the free version you get the info in 3 hour blocks, if you pay you get it by the hour.

    I started paying a few months ago, I figured I look at the app so often that I was actually more than happy to give them $33/year.

    HALT!

    “There are a number of challenges with the replacement of the Wynyard Crossing bridge. The most significant is our ability to complete the connection by the time the America’s Cup starts,” said Panuku’s Development Director, Allan Young.

    “It may feel like we’re pushing pause on progress, but we want to ensure that what is built is going to be of the highest quality and design innovation.

    We want to make a positive and memorable contribution to Auckland’s city centre and waterfront by giving Aucklanders something they can be proud of,” said Young.

    By pushing pause now and continuing to progress the project while the resource consent application is being processed, we’re going to be in a much stronger position to hit fast forward again once the America’s Cup and APEC have finished.

    Basalt 'Firbreglass' Cloth

    Just reading this, sounds pretty cool.  

     

    https://www.swellnet.com/news/design-outline/2019/06/27/new-cloth-on-the-block.

     

    The base material is basalt, nothing added or bonded. Basalt is melted at about 1,500° and the liquid is blown through tiny holes to make strands of filament which are then woven into cloth. You've essentially got a rock in fabric form.

     

    The strength test in this youtube link is pretty impressive.

    Shipping Insurance

    in MarineTalk

    Posted

    Just reading about a fire one of the Maersk ships had and how they are billing companies who had containers on board under 'General Average'.  Never heard of that but it sounds rather convenient to the shipping company.

     

    Must remember not to sniff at insurance if I ever ship anything anywhere again...

     

    https://worldmaritimenews.com/archives/249064/maersk-honam-battling-a-fire-for-over-a-month/

     

    Maersk Line said earlier that the berthing and discharging operations of the fire-ravaged boxship would result in high extraordinary costs.

    The company has therefore decided to declare General Average, under which all parties with a financial interest in the voyage are to proportionally share the losses resulting from the incident.

    British International Freight Association (BIFA) said insurance claims resulting from the fire would be hundreds of millions of dollars.

     

     

    'Wedgie' anchor sail

    in TechTalk

    Posted

    Anyone use one of these?

    However, it was on that very first meeting that Keith gave us one priceless piece of information when he told us of the need for a two-wing wedge riding sail in these wild waters. Riding sails have been used for hundreds of years to stabilise boats at anchor to prevent, or at least lessen, the sheering motion that can develop as the wind picks up. This maddening and potentially dangerous anchor dance affects some yachts more than others, especially lighter, faster modern hull designs. But as wind speed increases even boats that normally lie well will eventually start to sheer. Gecko was no exception and tongue in cheek we rated her as a six out of ten on our 'international sheering scale' standardised to a force eight gale.

    This sheering motion can be wearing on the nerves and tiring especially when it becomes violent with the boat rolling savagely to leeward as it is jerked back around at the end of the 'tack'. Yet a far more dangerous possibility is sheering's potential to break out even well set anchors.

    Traditionally a ketch would hoist the mizzen to achieve the aim of holding the boat bow into the wind. Other techniques to reduce sheering are setting two anchors, an anchor or drogue hung off the anchor chain in the bow, a line from abeam to the anchor chain to offset the angle of attack, a bucket or drogue hung off the stern, or even anchoring stern to! None of these techniques are particularly efficient. Some even seem like acts of pure desperation while others are unseamanlike, being positively dangerous should a dragging anchor need to be urgently hauled and redeployed.

    Keith had come up with his elegant solution to the sheering problem many years ago on the Orkney Islands during a force 10 North Atlantic gale in Scapa Flow. He had hoisted the mizzen of his ketch to steady the boat but, as the wind speed increased, the sail began to flog violently until it literally exploded. His solution was to jury rig the storm jib as a two-wing wedge riding sail off the backstay.

    Keith quickly sketched the rig for us and, on the morrow, rowed over again to help set up our storm jib as a 'wedgie'. Subsequent gales saw us increasingly proficient at rigging the sail, which held Gecko steady when normally she would have been sheering wildly.

    It was during one force nine gale, when we were moored upwind of two other yachts, that the full impact of the technique became obvious. With our wedgie rigged in the stern we watched as our neighbour started to sheer violently from side to side. The next day they came over to ask how that “funny sail” worked, as the motion on their boat had been so bad they had been forced ashore

    I'm not sure if that thing is a sure sign I'm getting old or if it actually is the most stupid thing this side of the black stump.

     

    Wonder how it'd go out in the channel about now....

    Just stumbled across this website, bloody brilliant.

     

    Flick between LINZ charts, Navionics Sonar, Navionics nav, Satellite, Street, the whole shebang.

     

    And uses location services so GPS enabled.

     

    Chapeau whoever did that!

    Not sold.

     

    Not officially anyway, or at least that's my take on it. ;-) (ie - I doubt it'll be relisted)

     

    Sounded like it needed a new donk or at least some work on the current one. 

     

    Seemed like a very good buy on the face of it.

    The Car Regos is for a system which can recognise them so if you lodge yours with them all you have to do is drive to you boat then drive home, no pissing around with permits, tickets and crap like that.

     

    thanks KM, that sounds good and I shall return my rego numbers accordingly.

     

    Leaves me wondering why they don't put relevant tidbits like that in the emails they send out though...

    Fresh in from the w/h team, what's with the bottom line?  Are they going to ticket you if you don't use the car with the correct rego?  Sounds like an administration nightmare.

    Coromandel harbour as cruising destination

    Was in there last week, town was surprisingly busy, 15 dinks up the creek.

     

    I thought about taking the boat right up the creek into town but was a little late (there are channel markers starting a few hundred meters past the main wharf), would have got up ok on a 3.2m tide and 5'6 draft (imagine you might draw a foot (or 2?) more than that BP).  Tied up to the main wharf but was down to 6 inches under the keel at one stage (an hour before high).  

     

    Called into the butcher shop and got some fresh chops and sausages.

     

    The Peppertree is quite good to eat at.  As is the Mussel Kitchen but that's 3-4km out of town.  Personally I just get an apple donut from the bakery.   ;-)

     

    There is quite a cool little art shop called Weta which always has cool stuff worth a look even if you're not buying.

     

    Barry Brickels Driving Creek railway is quite good, (again 2-3km out of town), not cheap to go up but worth doing.

     There are also calibration settings you might want to try if the helm is moving in a regularly port starboard.

     Thanks crazy, that's exactly what it's doing and it seems to wander less when motoring so that explains the gimbal.

     

    Is there a way of recalibrating it?

     

    IT - it's not interfaced, most of the time I just steer everywhere, doesn't bother me so much but guess if it worked properly I'd probably use it more.  Do you sell these?
