I've just discovered the Signal K sever option in the CerboGX. I spent a lot of time playing around with it on this holiday as there was a lot of downtime due to the weather. There is an amazing amount of info available (250+ data feeds for my boat) as it has the NMEA2000 info + all the Victron info. Haven't gotten the graphs working yet but I'll have to try that next.

This is a good place to get the anodes. Don't forget to change the internal anode for the saildrive too while you are out of the water. Its a big nut on the side of the saildrive that you access from inside the boat. https://chalmersmarine.co.nz/

Done!

Wow What a Cool looking boat. Definitely looks like a modern version of Extreme but with all the modern fruit.

I did my submission today.

Good point. I used 32mm 8 braid Polyester on mine. A bit more difficult to splice but can't unwind. Mine also has a nice 22mm stainless swivel on the top but the swivel on the top of the chain does all the work.

People seem to love them unless you in a location with wind against tide and it makes it hit the side of the boat. I have one for my cat but the bridal is short so that the fergie can hit my hulls. Its really nice to pick up as the top of the fergie is just below the front beam.

I have the B&G V3100 which i assume is just the same. The extra transmission power is noticeable and well worth the extra $$$ over the 2.5w version.

There is a really interesting map on this page that shows where it has and hasn't been found. It must need updating as none of the new BOI locations are included. https://www.marinepests.nz/interactive-caulerpa-map Interesting that it is not in the popular anchorages put more in the high current areas. Also interesting that the top of Coromandel and bottom of great barrier have it everywhere. Seems like an easy spot for it to spread via currents to all of the gulf.

We couldn't use the Torbay Buoy this year as it was in the middle of the Oceanbridge Regatta Courses and that 17nm course is a bit long for the general fleet, so we come up with some different options this year. With the light winds forecast we chose a course using the Takapuna Buoy and finishing off the Viaduct. Frank racing actually beat the committee boat to the finish line, getting around the course in 46min and our slowest boat was 3hr 50min, coming in just before the 4hr cut off, so I guess we got it spot on. People seem to be understanding this event is a "festiva

Yep I m a happy owner of a pair of SD20's with about 3500 hours on each of them now. They seem very scary in concept but actually seem pretty bloody simple so long as you look after them (which isn't much). Only issue I've had in 30,000nm is from a fishing line around the prop that cut into the seal. The SD20 and 3YM30 seem like a bloody good combo.

We (NZ Multihull Yacht Club) were lucky enough to get a tour of their factory recently. They are the real deal and are building a very clever but simple boat. They are doing it the Kiwi way and are increadly knowledgable on what they are doing. They ended the night by letting us raid the Carbon scraps bin - best "Party Favour" ever for a bunch of DIYer multihullers!

Wow Jon, you really see the real estate of your deck in that photo. The OC tender looks tiny!

We have the Victron GX system that talks to the solar and BMS of our batteries. When I leave the boat, I set the max charge voltage to 13.4v which seems to keep the batteries at about 70%ish. With this system, you can remotely log in and change the settings, so a few days before we go away, I let it charge back to full to be balanced and ready to go when we get on the boat.
