    Im sorry Zoe but Id be very confident that none of the recreational boats in Nz were responsible for bringing Fan Worm or calupera to NZ. And won't bring the sea star. The focus has to be on international shipping. 

    I agree that we need to take responsibility to stop spread now that it is here but there needs to as much effort in allowing effective control by mandating appropriate antifouls. The current ones aren't really up to it. 

    There is a huge focus on international shipping - NZ has led the way on this so much so that other countries have followed suit. But there is also a focus on domestic boats because while the international boats might bring them here, it's the domestic boats that carry them around. 




    It's outside my sphere of knowledge but Biosecurity NZ produce an interesting newsletter about this work that you might be interested in:

    Hi Zoe thanks for letting us know you are the newsletter editor . 

    The number one tool for boat owners to combat marine pests is effective  antifoul . There has been mention on clean below good to go about Selektope . Hempel paints have a Selektope containing  antifoul available offshore . I have emailed the Hempel distributor but they don’t reply . We need to get proven effective antifouls here pronto , the soft coprous oxide paints just don’t cut the mustard and aren’t great for the seafloor either . Pressure needs to be applied to whichever Govt department approves antifouls to get these emerging paints here ASAP .

    I'll see what I can find out about Selektope and if the EPA representative can address it (either generally or specifically) during the webinar. I know from speaking with some of the antifoul coating companies (not that one) that they are working to get new products to market in NZ and that we have high environmental thresholds they have to meet.

  3. My personal opinion?

    The reasons are economic and environmental. 
    We don't go around scattering gorse seeds into beautiful places (or productive farms) that don't have gorse. 

    Likewise we don't want to infect somewhere like the Poor Knights with fan worm (or any other pest) either unintentionally or intentionally. Most boat owners get that and are onboard with it. And so far the councils and MPI are actually doing a pretty good job of finding it quickly and squashing it where it pops up in new places. 

    Fanworm is pretty nasty but it's not the worst marine pest we could have here. The Northern Pacific Seastar is one of the worst. And if we are doing a good job of protecting ourselves from fanworm, then the Seastar has a much reduced chance of getting here, and of spreading if it does get here. 

    But that doesn't negate the fact that it's hard on boat owners with challenges like antifoul paints not quite working as well as they used to, infrastructure getting booked up, costs, and the like. Hence the webinars to enable a good discussion between experts. 

    This Seastar video is from Melbourne. Imagine that in the Bay of Islands or the Sounds. (Info here https://www.mpi.govt.nz/biosecurity/pests-and-diseases-not-in-new-zealand/ocean-pests-and-diseases-not-in-nz/northern-pacific-seastar/ )

  4. I did, it was before Facebook and Twitter etc were popular and was definitely a bit ahead of its time back then! 

    I am glad you don't want to unsubscribe - I obviously got the wrong end of the stick.

    Thank you for drawing attention to the webinar - it will be great to see more boat owners there (and subscribed to the newsletter). It'll be recorded too.

  5. Hi Addem, I look after this newsletter. I also have a long history going back around 20 years with Crew.org.nz (I founded it!) although I'm doing less (actually, zero) sailing these days (kids, work) and just drop in sometimes to see what's up. Firstly, the 'Clean Below?' newsletter goes widely to a list of subscribers. I promise you are only on there because you have signed up, or someone has signed you up. Maybe at a boat show?  You can definitely unsubscribe at any time - just use the link on the bottom of the email or reply to the email and we'll sort it for you. If anyone reading this would like to get the newsletters, just sign up on the website www.marinepests.nz/news 

    We hope that many of you 'Crew.org.nz-ers' will come along to the webinars. Marine biosecurity is a complex field with a huge range of considerations and TON/TOS have arranged these webinars to open up discussion, build understanding on both sides, and continuously to reflect this in its stories and newsletters..

  6. Thanks for this guys. I have compiled it into some bullet points - all anonymous. The intention is to use it in a newsletter about marine biosecurity. If you'd like to see it before it is published, or are curious about where it's going, please just send me an email - zoe@wildemedia.co.nz - I'll be happy to show you. 

  7. Hi guys 

    I hope everyone is well and still enjoying boating! Great to see the forum still going strong. While I hear that your boat is supposed to get bigger as you get older, mine is much smaller and I am down to around 4m LOA with a little dinghy. I am sure I should own a fifty footer by now. But that's not why I am writing.

    I am doing a little research into the correlation between a clean or dirty bum and boat performance.  I'd love to hear your anecdates/experiences and before and after statistics, for possible use in an online story. Also feel free to email me - zoe@wildemedia.co.nz 

    Many thanks! 

  8. Thanks everyone, the 'any time above high tide' sounds like a good rule of thumb to me and my mathematically incapable brain.

    Wal, we have a TV and numerous iPads to keep them busy but weird thing is they want to be outside! 

  9. Hi guys


    Long time no see. I've had four children since I last posted properly and now they are now all sailing opti's! So a lot of time has gone by.  


    After 10+ years of being boatless, I am lucky enough to be helping look after my father's Logan 33 which we have recently moved to Milford Marina.


    It draws just over 60cm - it's a gorgeous boat and we want to get out and use it more.


    I am trying to get a handle on the tides and depths at the entrance.


    Is there any simple answer as to the time either side of high tide we are going to be okay to get in and out? 


    Or am I going to have to get my calculator out....  which has all sorts of possibilities for ways to go wrong. 


    Advice appreciated! 





  10. Don't worry Wheels I gave up worrying about anything much like that a while ago! Four kids does that to you.


    Is it Northland you are talking about?


    I have aa general understanding of the issues but not of the specifics so I just took a look at the web page.




    If I understand it correctly do they need ask for an antifoul in the last six months OR a lift and wash in the last month. So you'd be okay with your 2-3 year antifoul so long as you'd hauled out in the last month - and yes I know hauling out ain't always cheap or always easy to get to. 


    That's the marinas. The council itself just requires you to be free of marine pests if they inspect you. Other councils are a bit different. 


    I can't answer for the shipping I know nothing at all about that! 


    I am not sure if that helps your case or not? 

  11. HI guys


    I can't start talking about stuff I am not an expert about on here but having seen it from a number of perspectives this is my understanding: 


    - Remember that Auckland does still have locations  - such as Great Barrier - that need protecting. Please be vigilant. 


    - If it is indeed too late for Fanworm, there need to be good practices in place for whatever the next pest is that arises as a threat


    - From what I can tell if you keep your boat clean and keep evidence of lift and wash and antifouling (such as receipts) you are pretty much going to be okay but it pays to check ahead with the council and the marina because they have slightly different requirements.  


    - Marinas are looking for solutions but this pest is really problematic. You can't just scrape it off and if you do it'll just come back (in force). There are some technologies around that may help - such as ultrasonic stuff - but nothing (I have heard of) that's proven yet. Let's hope for some good news soon on that front. 

  12. Hi Crew.org.nz, 


    Sharing this info which may be of interest to you. Councils in Northland, Waikato (Coromandel), BOP and Auckland want to make sure that you are aware of their rules, and also of the requirements of marinas that you are visiting, so you can get ready before the summer. 


    They all have slightly different requirements so it's important that you check ahead. 





    Councils and marinas continue to combat spread of marine pests


    Turning up with a clean hull is the best guarantee of a warm welcome for boaties planning to cruise to other regions this summer, as regional councils and marinas continue to combat the spread of marine pests such as Mediterranean fanworm.


    And now there’s a new easy way for boaties to check out the council rules and marina requirements in place at their chosen destination, with the launch of a new website: www.marinepests.nz


    In Northland, Waikato (which includes the Coromandel) and the Bay of Plenty, regional councils are stepping up their summer surveillance programmes, which are already underway. 


    Any vessels found to be carrying Mediterranean fanworm may be required to be cleaned at the owners’ expense. In Northland, the owners may also be subject to a $500 fine.


    Meanwhile, marinas in the three regions are continuing to require proof of either new antifoul within the previous six months, or a lift and wash within one month of leaving an infected area, before allowing vessels to berth. Haulout/antifoul receipts are the easiest form of evidence to provide.


    Although a lift and wash prior to moving to a new area is generally sufficient to comply, boat owners are encouraged to double-check hard-to-reach ‘niche’ areas where marine pests may remain (the base of the keel, bow thrusters, intakes/outlets, prop and rudder areas) before their vessel is returned to the water.


    • Northland Regional Council has also been developing a new Marine Pathways Management Plan and is looking at rules that would limit the amount of biofouling permitted on hulls.


    The new pathways plan is scheduled to be made available for public consultation in February 2017.
