    Actually... There is an update to this as of Novemebr 11th, 2020... Here it is (Quoted from the "Down Under Rally" folks..... ANNOUNCING A NEW EXEMPTION CATEGORY After the many months of lobbying national, state agencies and politicians by the OCC, The Down Under Rally and a supportive senior politician, the OCC has received a letter from the Australian Border Force advising that the Australian Government has agreed to an additional exemption category to the COVID-19 inbound travel restrictions as follows: "persons who reside on a vessel that seeks safe port at the closest appointed port for reprovisioning or safety reasons for a limited duration, supported by the relevant State/Territory where safe haven is sought." We are clarifying the application process which we understand will involve at least 4 steps including QLD Border Exemption, Visa, Commonwealth Border Exemption Application and Queensland Quarantine Exemption. Once clarified the application process will be published. At this stage Queensland is the only state that has indicated it will accept foreign yachts/nationals under this criteria. It is likely that Bundaberg will be the best port of entry given recent arrival procedures for Australian Yachts facilitated by Bundaberg Port Marina & The Down Under Rally. The 4 consecutive application processes are expected to take at least 4 -6 weeks to complete. Yachts in the South Pacific Cyclone zone that are still seeking safe haven and are wanting to sail to Queensland this year or early in 2021 are invited to contact the Down Under Rally to receive updates regarding the application process.

    New sail order headache

    The 3di sails are bought for shape performance, they are for a target market with the money justification to burn. They do deliver amazing performance but at a commensurate 'amazing' price. They should also not wind up being almost 40% over weight. We had a screecher quoted for our F36/39 trimaran. The 'high' performance option sails were very different in cost! The North 3di being almost 4X (3.89 times) as expensive as the sail we chose using Evolution Sails own laminate. I'd had experience with North's 3DL sails on a boat used for only racing and seen how far off the mark that the marketing department can go.... So chose not to go down the path of 3di sails until their cruising-life longevity is proven out. I (unfortunately) don't trust that North will follow thru and make things wright after my experience with the 3DL. I've attached the sail quotes for our boat to show the spread in costs for what are essentially race worthy sails that have good shape holding abilities for a somewhat higher performance boat like ours.

    They wrote back saying that they Can Not insure Trimarans!

    Insurance AGENTS

    Having a Quote done by these guys this month for a 40' Trimaran. We are where they are located in Opua, NZ and checking both worldwide liability and hull insurance costs. They did recently have a bad review on the local Opua Cruisers site and we are looking into that also... Will update if I hear anything. We are presently with Jackline, but it is very expensive, Wed are in the Canadian Ships Registry and cruising west to the Indian Ocean over the next 24 months.

    Firefly charging

    It might be worth buying the serpentine belt, even at 105 amps. We've had to dial back our Balmar to less than 80 amps to prevent undue belt wear and constant attention. We have a Yanmar 3GM30F a Balmar 621-VUP-MC-100-SV-KIT (12v 6-series Alternator) with the MC-614 Max Charge alt. control charging LiPO4 12v bank 400AH. The charge acceptance on the batteries is just too high and the 100 amp alternator will destroy the standard Yanmar conversion belt.

    USVI - Reliable Mobile Wifi (Please help!)

    I highly recommend getting a cellular modem and an antenna. The RUT240 is excellent and this enclosure/antenna for the RUT240 works very well. The RUT240 cellular modem mounts inside the antenna enclosure. There is both a local are network (LAN) antenna and a booster/antenna for wireless LTE reception. It's a great way t go and we are able to pick up very weak cell signals with this in areas that otherwise have too poor reception. https://quwireless.com/quspot-rut240-rut230

    Firefly charging

    It would be a mistake to absorb charge to 14.6, especially if the batteries are in an ambient temperature above 77 F. (even more so if termination of the abs-cycle Time or Current is not available to your charger) . The manual also recommends temperature compensation as follows "If you have hardware that allows the user to enter a temperature coefficient, use 24mV/C° for temperature compensation." This would be more critical if operating in a' hot climate'. I strongly recommend that you do not rely on a manual shut-down of the charger as possibly suggested. It is inevitable that this will be missed, Do NOT rely on wiring losses to compensate for the over-voltage since at the end of the abs-cycle the charge current is so low that the voltage drop in the wiring will be virtually non-existent. Get the correct charger for these wonderful new and expensive batteries. As a side note; The link (sighted above) is more than just a bit biased - as it is a Firefly Power Point Presentation - Flooded Lead/Acid batteries do not have a best "cost performance" at an 80% PSOC. Flooded cells almost always have the best cost performance when a roughly 50% SOC point of recharge is used. Yes, cycle life goes down but the cost efficiency goes way up. Firefly's use of an 80% point is just a marketing ploy to make the cost efficiency comparison look overwhelming favorable to their cells. (Firefly batteries are fantastic, but the oversell on cost efficiency is unfair)

    How often (if ever) do you miss the range that diesel storage used to provide (could you describe your experience about the range shift)? What design is the boat? Do you ever miss having an engine driven alternator? You wrote: "For the cost of a diesel plus installation (and the installation is as much as the engine), its very easy to have electric motor with tens of KWH of batteries.".... Are you counting the labor to install the electric propulsion system when you made this comparison? and what about the cost of the diesel when only 'just' re-powering (when the fuel/electric/exhaust/cooling is already there to hook up to)... but you have all the electrics to integrate/install on the electric conversion?

    Gunkholing in the Broken Group and Broughton Islands.... I could spend 20X that amount of time and be someplace new every few days. It was cruising heaven

    I actually can-not carry more PV (as a Trimaran), I do not want to step/walk on modules so I don't take advantage of the extra area....all my PV is mounted off-deck on the main hull; which is much smaller/narrower than any modern 40 foot mono. We do have a good radar arch and it holds allot of PV on our VERY narrow stern area. I think this has more to do with light an efficient sailing boats. A Trimaran can SAIL where some cruising mono's are saddled with more weight in just their keel than an equivalent light weight cruising trimaran has for it's entire laden displacement. As to the PNW....We did a 45 day trip in the Pacific Northwet from Vancouver island up the inside of Vancouver Island with all the passes/rapids you refer to, in 45 days we burned just 4 gallons of fuel. On our present trip... we are three years and some months into it. In those 3+ years we have used a total of 204 gallons, this trip had allot of atoll passes, some mostly winless passages (Nuku-Hiva- Fakarava), and the ITZ to deal with. As you point out...A boat that sails well has more to do with this. There is no reason that a 40' mono can't have a 25 HP engine and do just fine, I had an old heavy 40' OSTAR boat converted to cruising that had a Volvo MD11c - which is a smaller engine, - that boat made three circumnavigations, two of which were cruising trips... she did just fine, But I agree, if you have a 22+ ton 40 footer that you are probably stuck with diesel as your only option.

    Here is the track from the Fiji Met office, https://www.met.gov.fj/ looks like Nadi was spared the high winds, anyone heard anything from there?

    Curious,... For ABYC.... 'Nominal voltage' or 'peak/max voltage' ? I think that the normal (read accepted) dielectric potential of skin breaks down at 60 vdc? The NEC uses nominal voltage and at 60 VDC I think the DC rules all changes

    Not that I would ever choose that battery for a marine install... let's re-run your numbers. The statement (from the manufacturer) was that there is a full 920 kWh of "available" energy from that battery (this still leaves a 45 minute 'reserve' capacity). So you need to calculate on that basis. Our 40 foot boat (47 feet LOA) uses a 24 hp engine. This would be replaced with a 20kW electric. So our time at FULL THROTTLE is.... 61.6 hours of motoring at a ridiculously high throttle. Let's throttle back to an appropriate cruising rpm at 2/3 throttle and we have a bit over 92 hours (close to three days time). It's obvious that we don't need a battery this big, nor the overly long charge times.... Our boat has all the solar on the main hull (just as a mono-hull) We are a Tri and we can only carry 800 watts of PV (most of the catamarans that we see carry over 1,200 watts of PV) and we figure we need only a 50 mile range from our engine. We have a Watt&Sea to charge while sailing.... But lets look at recharge time for our 'normal 2 mile range of motoring that's 1.46 KwHrs or 2.8 hours of charging in full sun. That is less than 1/2 a full sun day of PV charging.... but we have the watt&Sea which routinely does 25 amps up to 40 amps.... so when sailing it would (in ideal conditions) take about 1-1/2 hours time to recharge the days usage for our 'normal' needs. Let's double that for 'less than ideal' conditions and call it less than three hours of charging time while sailing at our normal sailing speeds. As a side note; Let's assume a 23% loss from engine to prop on "brake-hp' for the 24hp diesel and 12% for the electric and a 8% loss for the re-charge on Lithium/C/C &Wiring.... sort of a wash in my mind here. Plus our engine compartment could go from this > To > This.... see picture

    And the times they are a changing.... https://www.cbsnews.com/video/renewable-energy-hits-record-high-growth/?ftag=CNM-00-10aac3a CBS News; "About 90% of all new energy generated this year has been renewable...." https://www.unilad.co.uk/science/solar-is-officially-the-cheapest-electricity-in-history/ IEEE "According to a new report from the International Energy Agency (IEA), solar has become the cheapest source of electricity for utility companies to build..." Or if you prefer; a graphical representation from "Our World in Data" https://singularityhub.com/2020/12/13/why-the-price-of-new-solar-electricity-fell-an-incredible-89-in-the-last-decade/our-world-in-data-price-solar-electricity-10-years/ ... sorry for the thread drift but I just felt the need to point out that all of the metrics for power generation, sourcing, embedded carbon and rapidly changing. Projects like this hybrid and pure electric boats are edging their way towards reality and long distance cruisers are taking notice.
