Haha, I didn't click. As some of my students used to say, the Wurry Furry (spelt phonetically) to be a play on the Maori pronounciation of it.

Initially Durapox was never meant for the Marine Market here in NZ and is why we don't see it well promoted for such here. It was used mainly in the Automotive and Industrial markets. Some of you that have a bit of Car paint background will know the name 2K, which is the primer. In fact Resene actually advertised it to the Automotive Industry as having been used on the AV boats. Yet as far as I know, it was never promoted as such in the Marine industry. Go figure. Maybe Resin view it as they already have enough products in the Marine industry, why complicate it more. Oz promote it heavil

Is it in Whanganui, or Whangarei? I have a feeling that is a comment that has sailed right over my head But in case not, the original Wharehouse was in Auckland.

The problem Hempel had in NZ originally was that the Owner was mostly interested in Commercial Shipping. He was originally one of the big cheeses of Nalder and Biddle of Nelson. The NZ operation did do retail, but not a lot more than someone walking in off the street into the front of their Wharehouse. Possibly the biggest advertising they got was me talking about the product. Now that Hempels own the wharehouse, I can only assume the product range will be increasing and maybe advertising. Psyche is correct that International and Altec for that matter are recognised because they both have

There was another listed in TM recently. Just one pic of the outside and that looked bad enough. Asking price was $5K. I jokingly sent the Pic to a mate and asked if he thought that was a fair price, or if I should ask the lister for more to take it to the dump. There are still a few out there that think their Boats are worth way more than they are ever going to get for them.

Thats a good article. But I need to correct one error. 5 Boaties sitting around discussing the subject will result in 10 answers, not 6. The overall article highlights the one common point. There is no one simple answer and for every attempt to reduce Hull resistance through the water, there is a whole new set of Physical laws that fight against you. There is one important point that always needs to be kept in mind. Friction and Resistance to movement is as much your friend as is your enemy. If you have no friction/resistance, you will never sail into the wind at all, nor even sail bea

Using different words to say the same as been said, "Ain't no such thing as a cheap yacht". Boats cost you twice. As an example, lets say it was $100K to build. Over it's lifetime, it is going to one day cost you that $100K again. You can chip away at it year by year with maintenance, or do nothing and eventually have it get to the point were it is gong to cost you $100K to get it back to being a usable boat.

So either you did not read that paper, or you do not understand it (sorry I don't intend that to come across harshly). If you read it again, and you will see that it is exactly as I stated above and will go over again here. You will also see that this is not about an product fitted to a Hull somewhere and how well it works. This was nothing more than a lab test carried out by some Uni guys. Also they were using a range of frequencies and a very small test area. Basically no more than the surface of the transducer. I would expect that surface of the transducer.likely coupled to a plate, woul

You obviously don't watch the Infomercials on TV in the late night and early mornings then. Wow there are some wild claims in those shows. I have a major background in Sound, mostly audible sound, but also Ultra Sound. When this idea first hit the market, I had mentioned my concerns here on Crew and we had a big discuss about it. Fullers Ferries tried large units on the Ferrys a few years back now. They failed to do anything measurable in keeping the Hulls clean and they had them removed. We discussed the subject again then. The idea of using Ultra sound was first developed for lar

It's likely the coating keeping you clear of Barnacles. The Ultra sound devices are a total waste of time. They don't work and well tested and proven that they don't work. So who makes Seaspeed? Sounds interesting. I think over the next few years, these release type AF products are going to be like new Battery technology. Rapid intro's on to the market and each with a new idea in their coatings technology and for us, very difficult to keep up with developments. The reason why Hemples did not have a consumer Silicon product was due to the guy (a good friend of mine) originally importi

I have discussed the Hemples silicon based AF in the past, but a bit too early for most, as it was once only available for Commercial applications here in NZ. As in, it was only imported in 44Gal drums and went direct to shipyards. It's great to see that has changed and is now available to the average boater. As said above, it does not have Biocides in it. But the development came about for two reasons. Firstly for commercial, TBT was being phased out. Secondly, the Copper based AF's have had many of their ingrediants phased out from use and the performance of Copper Based is becoming poor.

Only a few weeks back I was talking about this Boat. (I have never posted a link to a FB page before. I hope people can open it. If not, can someone step in and make any changes required to allow that to happen) https://www.facebook.com/commerce/listing/3230743333911192/?media_id=1&ref=share_attachment

You would need to ask to varify Headroom of all these. But i am pretty sure they are decent from memory. But I am only 5'8", so everything seems roomy in my memory. https://www.trademe.co.nz/a/motors/boats-marine/yachts/keeler/listing/3558928522?bof=xcto6eba https://www.trademe.co.nz/a/motors/boats-marine/yachts/keeler/listing/3569741555?bof=xcto6eba How " modern" do you want?

I believe that has come to an end. Or was supposed to have.

Thats an old story now. The current one is that Tiwai will go and a Data centre is to be built and fed the power Tiwai takes. And yes, large Data Centres can take that kind of power. Google is using the same amount of energy as San Francisco uses.

Was it 2000 Tonne of Co2 they reported they would save per yr? $27mill for 2000t is a lot per tonne. I don't get how they say it will save the Council $200mill/yr. Or did they mean, "earn" the council. Which is one of my beefs, country wide councils should not be in opposition/competition to local businesses. But I won't go down that track further as I understand it is against the rules. Or is my entire post outside the rules? Happy if Admin wish to delete it.

When I saw that news item, I was thinking about the kaos that would be out there on the Gulf, when we have boaties not obeying the Nav laws now, imagine a thing traveling at multi hundreds of Kph zipping around. So in saying that, obviously such a thing being allowed to go that fast in Harbor limits will be out of the question. Travel between say Wellington and Lyttelton might be worth it, but Strait conditions is going to limit entry/exit. Sounds interesting and would be exciting to take, but it's going to need to be competative.

Arr OK, I was not sure how your line was going to be used. I was considering a line going around a winch, the cover ends up taking a lot of the drag and will move along the core. Even drag through sets of pulleys will do it. If weight is an issue, often the cover is removed or you can of course buy just the core alone. CRA sell a core only and they coat it to protect it from UV. Cheaper than buying a core and cover and then discarding the cover. They can also custom splice it to suit your needs.

OK, so aside from a possible reason other than ease of making the spice, be aware that the inner core is poor in regards to UV exposure. The last photo just above looks like it has been coated and that will give protection. The other possible issue is that the outer cover can slip over the core and the strain will come soley on the stitch. Nornally for full protection, we would also splice the outer cover along with the core. That way the line works in the way in which it was made. I see that the video makers also do a cover to cover splice and hence I was wondering why the Core only splic

I have been watching with interest the new Solid State Battery technology that Toyota has just produced. The Solid State battery is said to be able to accept a full charge in just 15mins, endure over 5000cycles BEFORE any significant drop in charge capacity, last for 30yrs in Vehicle applications, are lighter in weight and have greater capacity per/Kg. On top of all that, safer as they cannot catch fire and the Materials used and manufacturing ease will eventually make them much cheaper and dramatically bring down the cost of a Vehicle. However, this is that part I was a little shocked about

Is there a reason why the outer braid is removed?

When you say overhaul, are you meaning the box was overhauled? Things to check. 1: Is the oil level correct? This is most important. Many Marine boxes can overheat and then slip if the Oil level is even only a little bit too much over the full mark on the stick. If it has been topped up, that can be a common issue 2: If Oil is original, is it clean? You do not want to see any milkyness in it, as that will be a sign of water. You do not want to see any shimmering metal in it or brown or black bits from the friction material. It needs to be clean and it's smell should not have any burnt

In case I am not getting my points across well (which can be the case with me) I am going to simply post a link to an article. It's not the one I was wanting, but it is pretty close to what I am trying to express. The discussion is a complex one and I can't provide all the relevant info in a few posts. So if anyone is interested in the topic, please read. https://yachtsnet.co.uk/osmosis.htm Aside from that, I will continue to search and see if I can find some kind of online article, if one exists, in reference to the article I read from the International/Epiglass fellow. By the way, I coul

Sorry mate, but I am absolutely correct on the epiglass guy and the information made available by them. I will try and see if I can find the info, but it may not be something that is to be found on line. I can assure you that I am not far off the mark with the info. I can also assure you that anyone that is still using the planning technique is either not up with the latest info and thus misleading boat owner, or does know and is simply ripping off customers. Because there is a lot of money to be made doing it. Vinyl became available ruffly around 1980 by the way. Yes c

OK I am guilty of making comments that were far too broad in explanation of a discussion that is quite complex. Before I get into it, here are some usless information facts. Did you know Polyester was actually invented back in 1935. It's first use was for Radomes on Aircraft during the War. The first FRP(fibre reinforced plastic) or also called GRP(glass reinforced plastic) boat was built in 1942. The first GRP boat to be constructed in NZ was a small boat built by Arnold France in 1955. He continued to produce the designs making him the first NZ Fibreglass Boat Biulder, manufacturing un
