Ex Machina

It could probably survive a trip down the drain from east coast road to the nearest beach ? How would you empty 100+ litre saltwater aquarium ? it could be well established in a corner of some murky harbour were no one dives and it doesn’t get enough wave movement to get washed up

Can I just point out this is the best debate on crew org in quite some time .

Love the stuff ! I’ve saved a bit of coin on silicone since I got a roll .

Yeah well I’ve been stockpiling cyclone ruined pvc wedding marquees and I’m on the hunt for some cheap chlorine , just need some dive gear and I’m in business

Stranger sh*t has happened . Did you hear about the bloke that traveled nz releasing coarse fish for a lark ? Started out wanting a coarse fishery but it got a bit sinister towards the end it seems .

Having a punt at how it may have got there . looking at how much got displaced at barrier during cyclone Gabrielle and seeing the drift path of 888 from Fitzroy it may have just got there on the wind and currents . Going back to the 888 drift path , if some of the stuff did get displaced out of Fitzroy it could be all up the coast already .

I fear that most people’s first knowledge of it will be on 27th of December at red head or Albert passage . Good chance you will get turned away from entering the inner bay . Hell , even whangamumu and whangaruru could be affected by then .

If a spotted bohemian gadfly ever turns up in Whangarei town basin there will be MPI folks there within hours installing pheromone traps all around the nearby suburbs . 1 year later with caulerpa ?

But seriously . Someone needs to talk to the Americans yesterday about their eradication techniques . Rather than piss around with think tanks with boaties . The horse may have bolted for barrier and the mercs but it could possibly be kept under control if action is taken very soon . I imagine it would be a game of whack-a-mole but the alternative is rampant spread whilst hang wringing think tanks are taking place .

What’s the chance of finding some 888 wreckage nearby ?

Maybe it’s now the epitome of cool to sail straight back into the slower boats ?

Doesn’t seem like you will need a fancy phone to use the voLTE network ? iPhone 6 onwards are compatible as long as it has the latest OS . it’s a long way off though , SMS only by the end of 2024 and data not available until sometime in 2025 . It will simplify things on board I guess if you want internet . No need for gadgets and gizmos with antennas .

Nice setup , sponsor rings a few bells …https://akarana.co.nz/akarana-eatery/

Quite true . You are probably the most qualified person on the forum regarding aquatic flora and fauna , do you think Caulerpa is or could be a problem ?

Sounds straightforward ….PVC tarps , chlorine , some good underwater operators and approval from wherever it needs to come from and soon not next year when it will cost 100s instead of 10s of milliwongas https://www.researchgate.net/publication/250218150_Eradication_of_the_invasive_seaweed_Caulerpa_taxifolia_by_chlorine_bleach#:~:text=Based on these results%2C chlorine,to reach stolons and rhizoids.

You could get a Velocitek prostart or novasail . Not sure if wait times are still an issue for the Vakaros ?

Not Delaware but relevant . Eradication techniques are further down the page . https://www.fisheries.noaa.gov/west-coast/habitat-conservation/caulerpa-species-west-coast Seems quite involved but surely no more expensive than holding meetings , hiring consultants or underwater companies to check boats . 100% they know the information above that took me 2 minutes to find and any other methods of eradication , so why feck around and find out ?

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

Yeah I pondered doing that but I need two hands to bleed the injector pump . went for a small automotive pump that allows fuel to flow through when it’s turned off so lift pump can do its thing when the engine is running

Read a very interesting opinion by a fuel specialist who argued the full tank theory to stop condensation is a myth . he reckons the condensation is caused by the hot returning fuel from the engine eventually warms the whole tank if it’s run long enough . The tank expands a little bit displacing any air and it also usually becomes warmer than ambient temp . The tank then stays warm for hours and draws in cold air as it cools which then condenses on the walls . His conclusion is you can’t stop the water but you can filter it out . He also recommends 6 monthly dosing with biocide regardless

Have just finished putting in a new filtration system and polished the fuel in the tanks . Have two 280 ltr tanks which had a mild amount of bug , one worse than the other . One deck filler had a perished O ring letting in water ,that tank was worse than the other , tanks are connected so it spread via the connecting line. Shock dosed both tanks with fuelright cause I’ve had success with that in the past in a bulldozer . Polished both tanks with a cheap 40 ltr per min fuel transfer pump running through a cheap high flow water separating filter and 20mm clear vinyl hose . Connected pump t

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

Permatex have 5 or 6 hydrocarbon proof sealants and gasket goos

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