I have been down that track. My understanding is that the alarms are focused towards commercial new builds or if an insurance company states that is required in the policy. Victron battery chargers can support low voltage and heat alarms to overcome these requirements. ITech has about 8 alarms within the app so they have it covered as an audio alarm. ITech is a W.A based company and the price is certainly coming down a lot . My latest check $999 for the 160 anmp pro inbuilt bms and Bluetooth app.

I have wasted so much money on agms over the past 3 cruising yachts I have owned. Simply they don't like loads or being used below 12.5 volts. I fitted 3 iTechworld 160 pros 6 months ago and am so happy with the performances. I treat them like AGMs nothing added other than I can use the coffee machine and toaster without having to wake up the neighbours with the genset. I have a Victron dc/dc 40amp charger , Victron 70amp charger , and the 20amp solar when the suns out all with recommended fuses. In the app I can see the temperature on each battery, set alarms and see each individual cell voltage. I can also turn each battery off and on separately. Tonight I have turned 2 battery's Off and just running the fridges and diesel heat on the one battery just to see how quickly the one battery will charge from the overnight discarge. Use the recommended wire sizes and correct fuses and get a qualified sparky to check your work. That's what my insurance company suggested to me. I will never have a agm as house battery on my yachts again in my lifetime.




Lithium certainly seems the way to go now I am pretty keen to move away from AGMs.

Having done a little research since some of the comments above it doesn't look like the Australian standard is too arduous to meet and the main issue is with the internal BMS with AS/NZS 3004 requiring external BMS and an audio and visual alarm. Ive since watched several videos by Will Prowse (posted above by ActionSportsWA) and if he is indeed that knowledgeable in the subject then some of those battles - even the cheaper ones have in-built BMS's that most likely meet the AS/NZS 3004 except for the fact that they are not externally fitted..

So if to stay compliant even if it's just for insurance purposes, you'll have to fit an external BMS and alarm system. No big deal and not all that expensive in the big scheme of boat ownership, but if the Salty Captain batteries I linked to above use Prismatic cells and Victron (a well known and probably the market leader) uses the same cells, how is there a $1000 dollar difference for the same amp/h battery? BMS and Bluetooth connectivity I see being part of the difference, but as I noted you'd have to fit an external BMS anyway, and build quality. Both those seem to be what Will Prowse gets the most concerned about in his videos. Rarely does he mention the cell types or quality. Even some of the more expensive batteries had some cons which is what I think some of the posters above were trying to point out.

I am not trying to find the cheapest option here and I am not interested in a battery from Temu or Ali Express. But surely an Australian business selling within Australia must only be selling batteries that meet Australian standards right ??????

Or am I missing something?

My AGMs are not particularly all that old but I suspected they were buggered due to my own neglect.


I will almost definitely upgrade to LiFePO4 with an increased capacity. There are some great deals at the moment and LiFEPO4 batteries are definitely getting cheaper.

What I'm becoming more and more confused with are the actual cells used in the battery. EVA seems to be common but expensive. Maybe they are in the likes of Victron branded batteries. But this one from Salty Captain (didn't know they made batteries) seems like a good price and my research shows that's the battery cells are of a good quality also..

Has Lithium now largely just come down to brand names or is there still a big difference in the cells?

Beware of the anchor exclusion zone around the SW sector of the island, there are cables pipes and who knows what there. Morning cove has some visitor moorings in the south and you could possibly anchor over the shoal to the north. I have done both. A great bus service to Mona Vale for resupply etc

there is nowhere there to anchor. its either moorings or channel

nearest anchoring space would be morning bay

cheers,






Thank you ??



You can anchor in this area but I wouldn't leave your boat there overnight unattended.








That location is well within the anchor exclusion zone. The boundaries of which are well marked on the chart

im pretty sure unless it's changed that it is only within 200m of submarine cables that are well marked , Allan Lucas and the state government map doesn't say the entire area is prohibited from anchoring.



Interesting that the navy chart and state gov chart differ in that the state chart doesn't have the boundaries marked but nor does it show the many and various submarine cables and pipes. I don't think anchoring there would be wise as there is lots of commuter traffic after dark wizing around. I wouldn't think it wise to advise people that it is OK to anchor in this area. I reckon there could b
e a fair bit of debris to foul on too.
Thanks for pointing out the chart discrepancy


I have anchored in this area a number of times, other yachts and catamarans where also there getting supplies from church point. It is confusing on the chart but I believe there's signs where the cables are and 200 m exclusion each side. One South and another north west . The main advisory notes are just there to check your notes. Not indicating that is prohibited entire area .

Wow - 7ish boatspeed in 9 knots of breeze on a carbon tri is slow for generating apparent in light winds. I can do better under 40 year old reacher in my cedar ply cat. If you look at the stern you will see lots of turbulence. He gets excited about 5 knots of boat speed.

His money.


Yeah . I do wonder if he has just rented it...he has just rented a Harley to ride through Ukrainian while he was waiting to find a boat. ??

his worked hard over the years to jack up realestate and show us the world on a Harley and now try to sail a speed machine. This is going to get interesting!

Oh my god - such stupidity shown here. Now don't get me wrong I LOVE trimarans. I got my first at 15 years old, my second at 21, lived on board that and cruised it for 2 years with a growing family and was designing a 40ft version for the next boat. My best friend asked me to build him a trimaran which I did. As I was drawing my 40ft tri (it had so far taken about 2 years to design) even my best friend who was also a tri lover said I would be happier on a cat - Blasphemy! So I drew the accomodation plan of a 35ft cat - within minutes I had more than twice the room of the tri, with greater payload, same performance, easier construction, less bea, less cost and more resale. Needless to say - even this tri lover built the cat.

What the Bogan doesn't get is that Lagoons are not the ultimate expression of multi design. For some reason he thinks if a Lagoon can't sail he needs a tri. This is so stupid it beggars belief. He could have got a Schionning, or Grainger, or Pescott, or Outremer, or Chamberlin cat. Any good Aussie desigmed and built cat.

I predict he will find the Dragonfly is incredibly hard to live on compared to the cat. It won't take anywhere as much payload, it will be less comfy underway, will be twitchier to sail and on top of this - not able to be driven hard enough in its overloaded cruising state to go fast anyway. Our 31ft racing tri cruised slower than our non racing but performance oriented cat. The Dragonfly will be dragging her bum and going slow but this is the main thing - if he does want his crew to stay on board after a couple of days - he will not be able to push the tri at all to get peak performance.

The other thing people don't get about tris is that the do not allow you to get away from each other. The cabin sole is probably about 40cm wide. This means EVERY time you want to move you have to ask your partner to move. My wife and I were in our 20s when we did but it got old very very quickly with others. It is great to go aboard a mono or cat and be able to move without needing to orchestrate the move with the rest of the crew. You are going to hate each other in a few weeks unless you are so in love but they don't tell you that in a brochure

The silly thing with wing masts and tense ropes in the cockpit and loud banging interiors and awfully light boats, is that they make you slow down. In order to live on our tri, we had to throttle her back almost all the time. We throttle our cat back over 15 knots upwind and 18 downwind. Otherwise my family would mutiny and get off. Performance boats need to be able to do serious speeds in choppy water with a minium of effort and motion. And you don't get that from a carbon tri over specced on sails and masts that is dragging her bum because she is heavy. Real performance comes from getting up to 8 knots quickly in nice light winds. You don't need a carbon tri to do this.

THis is a great example of following a silly deep dive on the net instead of looking around and talking to people who pass you in nice boats. Well, it's his money to burn, and I think he is doing a good job of getting through it fast. The best way to get real performance is not to go carbon but to leave stuff behind. Make the boat lighter, cheaper and simple by keeping it simple - saves money and improves speed. Tris are a great buy for the singlehander or couple (you get all the shallow draft and speed advantages of a cat at cheap rates) , but get an Aussie one - a Simpson Liahona, a Chamberlin Cirro, or a Yank Harris is fine. But don't buy a tri because you think you will go faster - you won't.


He's a Harley Davison rider and fast car owner. All those performance boats you mention probably have a 3-4 year wait. Danny likes to buy new stuff of the shelf not waiting around for **** to happen. He is also successful business man and will use this as he's next platform to send him into retirement in his 50s.

I met this 53 year old retired realestate agent in Cairns 2024 with his first ever boat a lagoon 42. Looks like a change of plans now. He certainly lives life on the knife edge!
