  1. If you look around (trademe and marinaberths.com) there are not many berths for sale, take Bayswater and Hobsonville out of the equation and there are very few remaining berths advertised.

    Westhaven is not renewing any licences, the last expire in 2029, if you do the calculation buying a license + paying the OPEX is a little cheaper than rental for the same duration;

    Bayswater, Hobsonville and Pine Harbour - you can be sure OPEX will continue to increase significantly to pay for the purchase of the marina's (there has been the odd rumour he has been sniffing around Gulf Harbour

    Gulf Harbour has the (good) anomally of the very long licence, there is not one berth listed for sale there.

    Fairway Bay is rental only, Grant runs it really well and has a long waitlist

    Half Moon Bay, BBBYC, and Sandspit are incorporated societies so can only charge to cover costs. All these marinas are seeing increase in value of licences and very few berths for sale

    Orakei seems stable, always has been most expensive in Auckland

    Decisión can really come down to whether you want the security of "owning" your berth

    Final note is that the strongest demand is for big berths, 16m+.

  2. Unsure if the consents have been submitted yet, this is the last story in the local news

    http://www.localmatters.co.nz/News/Mahurangi+News/Mahurangi+News+archives/2016/April+2016/Steady+as+she+goes+for+river+dredging.html

    Also consider Auckland Council's Unitary Plan which proposes Warkworth's pop increase from 4,000 to 20,000 - 40,000, with most of this located in the Mahurangi catchment, somehow I do not think the sedimentation run off is going to reduce.

  3. NZ stats here

    http://www.drownbase.org.nz/annual-statistics/

    do not know if they include the Kaipara Bar accident.

    If you can wade thru all the charts in the 2015 report, the key numbers Page 14, are

    swimming           16

    powered boats    9

    sail                       1

    non powered        1

    diving                    9

    land based fishing 4

    other recreation      5

     

    the 2016 numbers to date show a similar trend. Yet the hysteria being generated by the media and other organisations eg Maritime NZ and Coastguard is in my view going way over the top.

     

    NZ suicides last year were >500 yet this is never mentioned

     

    An interesting view about the road toll here

    http://karldufresne.blogspot.co.nz/2016/12/the-road-toll-statistics-they-tried-to.html

    and how the rule of unintended consequences kicks in.

  4. Your rig should have fore and aft lowers, typical of Des' designs. These should stop the mast moving around - are they tight enough?

    Closest riggers to you would be Phil Ash at Gulf Harbour, he has done good work for me. They are very busy this time of the year, if you want a check might be best to take Romany around to Gulf Harbour

  5. The last Kiwi built cruiser racer would be Neil Bailey's Beale 45 Zucherro, absolute masterpiece by Lloyd Stephenson with an eye watering price to match  - you get what you pay for!

     

    It is fun at boat shows to ask the sellers of bendy type boats if the bulkheads are tabbed to the hulls, most claim to use "high strength polyurethane sealant", in other words no! Dufour say their bulkheads are tabbed in, using this to distinguish their boats from other competitors.

  6. When installing new log and depth sounder transducers (both Airmar OEM) I noted they came covered with warnings that they were not to be painted with Ketone (oil) based antifouling, only water based.

    Given that water based antifouling is rather scarce in NZ, and only in 4L tins, interested to hear people's experience/views

  7. Steve, as I mentioned previously an Isolation transformer is the best way to go, but this is for a fixed installation and you still need RCD's. I have one RCD between the inlet and the primary AC switchboard, then because I have an inverter there has to be another RCD on the outlet side of the inverter.

    IT commented about AS 3004 not mentioning EWOF's, these are covered in the NZ Electrical Safety Regulations 2010, see clauses 76,77 & 78

    http://www.legislation.govt.nz/regulation/public/2010/0036/latest/DLM2763501.html

    these seem to be a bit of a moving target with amendments every couple of years

  8. the Rolls Royce of manual pumps (at a price to match)

    http://www.go2marine.com/item/23684/edson-manual-diaphragm-pump-lever-action-side-inlet-30-gpm-117br-200.html

    on a more budget basis I second IT's nomination of the Henderson Mk V, toughest plastic body pump around

    for a large capacity electric pump I have gone with one of these

    https://www.amazon.com/Rule-Evacuator-8000-High-Capacity-Submersible/dp/B0084A9K40

    finding a hose you can stow is a bit of a challenge, I bought a lay flat hose which is not the best solution, as I could not find the alternative "concertina" style hose.

    A separate engine drive impeller pump (1.5 or 2")is a good step, do not consider using the engine's own pump - one blockage and the impeller will be history, besides on smaller engines these do not have such a high flow.

    The issue with the shaft mounted pumps (Erickson etc)is that the shaft has to be turning for them to be operating and in a flooding situation you may not necessarily want to be moving.

    Another alternative is a Pacer

    http://pacerpumps.com/industrialPumps.php

    Dashew fits these with an hydraulic drive to his expensive motorboats.

    An option if you have AC is a submersible centrifugal, or have the space to stow a separate motor driven pump.

  9. The electrical inspector from Warkworth checking boats at Sandspit has been getting stuck in on the DC side, I know of a couple of people who had to change wet batteries to sealed  ones due their not complying with the ventilation requirements.

    Galvanic isolators help to maintain isolation from other boats or marina leakage, but they can fail periodically and with most you only know if you test them. Only sure way for protection/isolation is an isolating transformer, either traditional windings type or an electronic type such as

    might be an interesting question to ask your respective marina to provide their own certificate of compliance to ANZS3004 part 1.

  10. Even with some advances the overall situation has not changed much, ie if you are basically a day sailor just wanting propulsion out/into the marina and can plug in for a recharge then electric has its points. But for cruising your favorite locale for some weeks, an IC engine is still the way to go.

    Just released:

    to get the 30 mile range it would need to be very flat water

  11. from a financial point of view, if you compare Alastair's $30k initial investment funded at an interest rate of 6% vs a monthly power cost of say $300, and assume there will be an annual increase to this cost of 2%, then the solar install is at break even after ~10 yrs. This does not consider any maintenance costs and I would expect after 10yrs the batteries will probably need replacing
