  1. Anyone thinking about cutting corners on a gas install should read this. Anyone else who ever uses propane on a boat should read it too: http://www.boatmoves.com/LT_Story.htm and watch this: They used a tiny amount of gas for that explosion from a little camping cylinder from a portable stove. It could have been much worse! NZ regs and awareness of propane risks are really lax compared to the UK. I've seen some really terrifying stuff here like gas bottles in the bilge! Gas bottles and things like califonts must always be in a place where
  2. This is exactly what a trolling motor isn't designed to do. People who are trolling for fish just want to move through the water at a low speed, they don't care if they are not moving over the ground or even going backwards with the tide against them. A trolling motor is designed for trolling slowly, not as propulsion to get you somewhere. The propellers have a very low pitch designed to move the boat very slowly and not overload the very low powered electric motor. Consequently, if you try to go against the tide you'll not really get anywhere. A trolling motor with the power and ran
  3. We used Cook islands flag when we were doing commercial charter and passenger work. The big advantage is Cook islands accept the same commercial surveys as MaritimeNZ, whereas if you go with UK or Jersey flag then the commercial survey requirements are not compatible with MaritimeNZ and you'd need two different surveys by two different surveyors (NZ commercial and flag state commercial), with conflicting requirements! Cook islands is very expensive though, lots of paperwork and a short renewal term, I would not recommend it unless you are commercial and operating in NZ waters. When w
  4. Ex charter boat from Thailand. Not sure how she ended up in Marlborough. Story goes something like this... She broke loose from a mooring there and was grounded, rudders broken off and lost, serious damage to the hulls around the rudders, damage to prop shafts and supports. At least one engine has been under water and they were both already due for replacement before the wreck. She was dragged up the nearest beach and very roughly patched up enough to make her watertight, then dragged back into the sea, towed to the marina and hauled out. Then sat in yard for quite a few years untouched, repo
  5. Sean (the developer of pypilot) is usually helpful and responsive unless he's out at sea so you'll be fine. Coding shouldn't be necessary but you might have to edit config files manually and use the linux command line (mostly just copying and pasting commands). There's enough documentation around to overcome most problems but it's not very organised, a combination of very rudimentary instructions with a lot of useful info in forum posts on the pypilot forum but it takes a while to hunt down an answer. Getting all the wifi and network connections set up was the tricky bit for us. The config too
  6. Check out pypilot, the brain is a Raspberry Pi zero and it is developed by one of the core OpenCPN developers. He also builds the hardware (motor controller etc.) very cheaply to order if you don't fancy DIY. It has built in control from a custom OpenCPN plugin and it can be connected to your existing autopilot pump or motor. It should work very well with openplotter. Keep your expensive proprietary autopilot as a spare or sell it before it becomes obsolete and buy 10 spare pypilots as back up! The pypilot uses all cheap, mass produced components so they might be more susceptible to
  7. Hi Fogg, Unfortunately there are a lot of middle men in the Torqeedo supply chain. Despite the apparently high price we have much tighter margins on Torqeedo than the brands we can import direct from the manufacturer and distribute ourselves. Please email sales AT electricboat.co.nz and we'll see what is the best we can do for you. We'll certainly beat any other NZ price though. Lithium batteries of that size require special and expensive shipping. Airfrieght is pretty much impossible. Then there's import duty, fumigation, GST, MPI costs on top and a ton of paperwork. I'm afraid impo
  8. The 2kw Torqeedo (5hp equivalent) motor is 15kg. The Combi is a bit heavier. You can use any suitable 24v battery. Lead acid batteries are cheap but heavy. Any size available. A Torqeedo 3.5kwh lithium battery is 25kg. A 5kwh Juice lithium battery made in NZ is 53kg.
  9. We've got a Torqeedo Cruise 2kw you can try out on the water here in Kerikeri, also a few other electric boats. You can see the power consumption of the Cruise on the display. Run it at 1.1kw and you'll get an idea of the power of the Travel 1103c. You'll be surprised how little power you use as long as you keep a knot or two below hull speed. Range depends on the shape and size of boat and factors like headwinds can make a big difference. Above all, you'll use way more power if you're in a hurry! Please tell us a bit more about your boat and how you use it, then I'll take a guess at
  10. Do you really need 3kw? that would be adequate for a 3 tonne displacement boat. For the Cruise 2 and larger motors you use a separate 24v or 48v battery(s) inside the boat, then you can just use a regular solar panel and charger. Our 4m catamarans have a 320w solar panel and a 1.1kw motor. We don't need to plug them in unless we get multiple bookings on the same day or consecutive cloudy days. Our 1.1 tonne English river launch has 640w of solar and we've never had to plug her in. With a 6m waterline she'll cruise at 5 knots on 1kw of power or 6 knots on 2kw. We limit her to about 75
  11. Yes, spare batteries are available and very easy to swap on and off at sea. Hold off and try it out before buying a spare battery though - if you're gentle with the throttle then the 1103c battery lasts a couple of hours at normal speeds and all day at low speeds (depending on size of boat). It has a maximum power of 1.1kw which is enough to push a 1.5tonne boat at about 1 knot below hull speed or a 1 tonne boat at full hull speed. That means it'll push a little dinghy around all day long as long as you resist that temptation to make more waves at hull speed without going any faster.
  12. We (electric boat co) can arrange for you to view and/or pick up a Torqeedo 1103c at the distribution warehouse in Auckland after lockdown ends. We have two units of our stock down there and no Torqeedos left in Kerikeri at the moment, just a Combi 2.5kw H-Thruster left up here and 5kw inboards. Anything else we can order in from overseas. Not sure when new stock is coming in yet. We'll give you a better price than anyone in Auckland. Shipping is expensive due to the lithium battery so Auckland pick up is a good idea if you can.
  13. Thanks for the mention Deep Purple. It's not listed on our website yet but we can now offer the Torqeedo 603 which is a de-rated version of the 1103 with reduced battery capacity. It saves you about $1000 and saves some weight too. Perfect if you just need to go out to a mooring and back. The 1103 has several hours running time at moderate speed, which is more than most people need. The standard 1103 is only 8kg and the battery is only 8kg too, really light weight and you are perfectly balanced with one in each hand. You put them on the boat one at a time so you never have to li
  14. We had our yacht repainted at Vuda point, total cowboys, made an almighty mess which all had to be stripped off before starting again somewhere else. It was two months of horrible work with a sander to get it all off. These were supposedly Vuda point's "recommended contractors" so I made the mistake of trusting them to get on with it while I was away for a few days. Ended up with paint on decks, fittings, windows and even some of the places that were supposed to be painted (but just one very thick coat without any of the necessary sanding or primers first!). The job was contracted to be spraye
  15. Unfortunately everything which really works has been made illegal. Some antifouling still works for some types of fouling but nothing works for all types any more. It might keep the barnacles off but the mussels and the slime are another matter... A quick light scrub every few weeks in summer and every few months in winter, take the fouling off before it gets bad is the most effective solution. Being based at Northcote point you can nip round into little shoal bay and dry out on the tide there to clean the bottom. Nobody seems to mind there as it's full of drying moorings anyway (it has b
