    Lyttelton community acts to stop spread of huge sea worms

    Local communities around Christchurch’s port are calling for urgent action to slow the spread of huge sea worms. “I can tell you now it’s catastrophic.

    He described the limited cleaning infrastructure currently offered for boats in Lyttelton as “abysmal”. It was especially difficult for recreational vessels larger than 10 tonnes because the club’s cleaning cradle could not hold them.

    Biosecurity New Zealand director of readiness and response John Walsh said the worms had been eradicated from other parts of the motu. “Tutukaka Marina in Northland, for example, we’ve had no detections there in five years after a local elimination effort and we think it has gone,” he said. “Picton and Waikawa Marinas in the Marlborough Sounds, we’ve had good cracks at it there... and have not been able to find any there for two years.”

    Oh crap , must’ve been the Auckland and Whangarei boats that went to watch sail GP what spread it there (purple font)

    The vessel is a Boston Whaler Conquest 305 and it would appear the boat is built like the proverbial brick out house considering the relative damage to the vessel compared to that of the ferry.

    I am guessing there may be some delamination below that gel coat though.

    Yeah sorry my bad . It Certainly won the conquest in this situation

    Thought about it but need cat3 lifelines. I don't know why given the shorthaul course barely covers Triple courses ground. Happy to be clipped on. 
     

    Getting motivated for the Triple Series though

    Ah bugger ,   no preachers frame up the front on DP

    Can anyone provide a link to a photo of the launch which hit the ferry? 

    It’s a trophy not a Boston whaler and not a launch either .  Heavy solid boats and it shows when you look at the difference in damage to either vessel .

    I believe that AHB gave up on attempting to contain MFW (mediteranian fan worm) in 2010, It is a filter feeder, basically cleans the water, sure it will take over from the "native" fanworm just like the pacific oyster did to the "native" oyster. apart from this being a guaranteed thing to happen what is the downside?? 

    Antifouling paint has been dumbed down to the extent that it is almost a waste of time to apply it against any and all marine animals / fanworms / crustaceans. The square barnacle, as I have recently found is doing extremely well in the Kaipara along with the tiny date mussel, and doesn't seem to be affected by the brackish water from Gabrielle. Oh and the Kaipara snapper fillets are currently nice and pink. Local folk law says the white flesh snapper fillets as shown in the news are most likely from snapper that have recently spawned.

    On the subject of antifoul . I spent a good deal time last week down a rabbit hole of active ingredients , legal and illegal . There are several off the shelf pharmaceuticals you could conceivably add to your paint to deter/kill inverterbrates . Most , if not all the ones worth considering bio-accumulate so probably won’t be for sale in antifoul . The most promising one is the main ingredient of “Selektope” . Hempel and chugoku are two Antifoul brands that have Selektope paints available but not in NZ . The Hempel distributor here has not replied to my email asking when and if Selektope antifouls will be available in NZ . 
     

    If you were in a certain profession you could easily get hold of the active ingredient and only a tiny amount is needed , just a couple of mils per litre . It’s fairly safe stuff but extremely toxic to aquatic invertebrates but apparently doesn’t bio accumulate . Marine pests NZ have mentioned it on their website so maybe we will see Selektope containing paints here sometime in the future .

    There were also some microbursts as far away from Westhaven, in Devonport. My Lotus was sitting in its cradle on the hard at DYC, and was picked up and dropped down hard enough to delaminate the hull from the stringers by over 50mm. Boat was written off. The actual storm cell centre, according to metservice, passed slightly south of Norht Head. Weird.

    Hope Rudolph didn’t buy that one ?

  7. the Westhaven one is still the best i reckon . 100ft yacht on its ear and the footage of the cat flying through the air where moments ago a ferry had just gone past .

    No, that is just when it switches from shore based to satelite.  It becomes a Tug/Special when it is detected via Satelite unless you have a subscription.

    When they go out of shore range the shore position stays at its last location with the time decaying, and a Satelite position indicator starts up.

    In the image below, the actual position is the top right one (received by Satelite)

    While the last shore based location is bottom left, and 13minutes old.

    Thanks for pointing that out , learn something everyday ! .  The whole situation is quite distressing and the way it unfolded could not be predicted .

    You definitely want the bridge open when you can, not a blanket closure. Think, for example, hospital employees who live on the shore.

    So far it's definitely a bit of a damp squib. Maybe the decision to close schools was the right one based on the forecast, but as I sit here cooped up in the house with the kids (and the in-laws) while it's neither windy not rainy, it does look like an overreaction in hindsight. 

    We are only getting 50 knot gusts here now two hours north , so if what we had earlier happens in Auckland it will be quite an event

    Non event south of manukau.norhibg in Papakura/te awamutu/Otorohanga/Huntly.Just annoying drizzle.Se don't bring much rain/wind southern districts.

    Coromandel will absorb it for those areas but Te Aroha will get absolutely nailed once it gets a bit of southing

    Have you looked at Eberspacher diesel ones? They also do a tank version or one that uses a normal type water cylinder. 

    That’s an interesting option . The boat has a heat exchanger type tank that’s only configured for shore power so could be plumbed in to a diesel heater I think .

  12. I’ve been Looking at ducted exhaust LPG water heaters like the suburban and camec style etc .

    Anyone here got one of these ? And do you have the tankless or tank version ? 

    The fitting options seem more flexible than a classic style califont  and probably easier to meet certification criteria too.

    A2t is Cat 3.  Which is the same as coastal classic but with a life raft, and most coastal boats carry a raft anyway. So if you're a coastal classic boat you have to choose one over the other. 

    We'd do both if it was an option. It's always less about the race and always more about the destination. What makes coastal, a2t, kauwau night race, ssanz anzac, (and now this), so attractive, is the after event.

    37 boats entered a2t in 2021. That's a lot of boats with phrf having to choose.

    Hopefully in future years it won't conflict.  It is a great idea. 

    Any ways.... 200 boats on a 200m start line is going to be pretty damn interesting...

    All good points !  My argument is those core of boats that do the long races and short handed series are very well catered for in terms of events year round . They very rarely enter the soft core races like R66 , coastal or bayweek etc so I doubt they will lose sleep over missing the harbour classic .
     

    There’s literally hundreds of race boats in Auckland that just club race and don’t do any major races or events . The Harbour classic just might get a lot of them out of the marinas on that day .
     

    I still think PHRF is a bloody facepalm and a YNZ rort for such a short race , who the hell wants to measure all their sails for that …and pay $70 for the pleasure .

    Smack bang in the middle of the Auckland to Tauranga.  Which is a great race where many boats with PHRF could also be.

    Such impeccable planning.

    Yeah -na  , the Auckland Tauranga boats are hardcore and wouldn’t feel like they are missing something would they ? ….north head  to Torbay and back ? And it’s more than PHRF it’s cat3+ too
