Can we make it?

Well, I guess the big question readers may be wondering is, when is the big day?

Actually, as you can imagine, its been much on my mind in recent weeks.

So, as I sat down to write this update, I took a look at the tide tables taking into account the three factors I have to work around;

  • must be a weekday.
  • must be off public roads before 7am.
  • idealy we would arrive at the boatramp about an hour before low tide.

I came up with Wednesday 27th November. Low tide of .94 at 7am and a nice high tide on a new moon of 3.34 at 12:23. Perfect.

I estimate we will be floating around 11:15am but I won’t push off until slack tide.

That’s it. I’ve said it. It’s in writing.

Can we make it? I think so, but … time will tell. That’s the thing about big projects. There are so many balls in the air, any of which could throw a spanner in the works!

Our status update is that I am currently batching aboard. No Deb has not come to her senses and left me. She’s in Alice Springs for the birth of our second grandchild! It’s all a bit surreal at the moment, but there is something magical about this season of our lives, the culmination of (nearly) four years work, the promise of summer and the joy of new birth, both here and in Alice.

The upside is, without Deb’s moderating influence, I am free to work seven days a week, on the last big push for splash-day.

So here’s where we are up to.

The galley is installed and the all-important gas certification is done. We were very lucky to have a local plumber who is licensed to certify gas installation and is willing to do boats. They are getting hard to find as not many are willing to assume the legal liability imposed on them by the regulators.

The fridge, cook-top and oven are all screwed in. Just the plumbing to go before we can fix down the sinks.

Locker fronts are fitted, and have been treated with two coats of varnish.

Updated restrictions meant we had to install a fire-proof splash-back behind the cooker. Also a gas detector has been installed on the foot space below the oven You can just see it.

The all important certification plate in the gas locker.

Actually, I’ve got something to say about the milk crates. They were thrown in as a temporary measure to stop the rusty bottles from staining the fresh paint while we sourced some brackets. Then I got to thinking. Why not fix them permanently?
They are light, strong, will not rust and easily fixed in place. With a bit of foam packing, the bottles would be wedged in tight. Yes, they are ugly and not very nautical looking, but practically speaking, they tick a lot of boxes. Hmmm … I’ll let that one percolate for a while. I’d be interested in any comments!

It was a big day we got the saloon door in. Finaly she was in “lock-up” stage!

Before Deb left for Alice, she got stuck into the last bit of unfinished painting. The outboard pod and fuel storage area under the cockpit seats. Once done, we were able to mount the outboards. I made up some aluminum checker-plate mounts which slotted on over rubber backing, to protect the fiberglass and provide some degree of vibration and sound absorption.

After that, we able to fix the throttle controls for the outboards, and start configuring the outboard control cables.

Running the outboard control cables.

There’s a whole lot of this sort of stuff going on at at the moment. My note book is full of sketches and notes. These are the dimensions for the outboard throttle cables.

But by far the biggest job since our last post has been the electrical system. It’s a major decision, that, if not done properly could have a major impact on life aboard. For those interested in the details, here’s a summary of our experiences and decision-making process.
The first decision, after calculating our potential loads, was what type of battery. For a catamaran, it’s hard to go past Lithium Phosphate, due to their weight / amp-hour capacity. The problem is, they are unbelievably expensive. It is possible, however, to sort- of build your own batteries, for about half the price. You purchase the various components and configure your own power pack. The problem with this approach is you are basically on your own. Lithium batteries are reliant upon software to keep them safe and prevent them from over/undercharging. Get that bit wrong and it’s a very expensive and potentially dangerous mistake. It’s a steep learning curve for the uninitiated.

The second option is to purchase the “brand name” batteries and add-ons. These come with all the electronics, protection and software built-in; but you pay for it. Inside, it’s mostly the same components as the DIY batteries, (there are only a couple of factories making Lithium battery cells), but what you get for your money is plug-and-play engineering. I toyed with building my own, but in the end recognsed my limits. So, $8,000 later, we have installed a fully integrated Victon system. Once the cost shock passed, I was very happy with the decision.

The eletrical hub is all done, just waiting for the electrons, to go live.

Apart from the anchor winch cabling and navigation, the house system is ready to go. Tomorrow I’ll trace the 240-volt cables, and next week the Victron suppliers will come and check everything before going live. They will also wire and certify the 240V installation.

Batteries, BMS (battery management system), system monitoring and battery protect unit. All these components talk to each other via Victron’s VE bus protocol. Their job is to protect the batteries. They are basically “gate-keepers”. All electricity gong in or out of the batteries goes through them. I’m waiting until after the experts have checked out my installation job, before tiding up the cabling and strapping down the batteries, in case changes have to be made.

Power has been installed to all the cabins with fans and USB power outlets. We decided to install the insulated ceiling liner above the main bed after a couple of icy nights. The remainder will be installed after the deck fittings are fitted.

Stanchion bases are fitted. Got to trim that butyl tape!

Installing the cockpit switchboard. They control the navigation and steaming lights.

This junction box is situated under the mast step, ready for the mast to be stood. The masthead and steaming lights will terminate here.  It’s connected to the cockpit switchboard.

This is the waterproof access point for the solar panels, AIS & GPS cabling to penetrate the turret roof. That little round thing is a GPS reciever.

Water tank deck inlet points are intalled.

I had originally intended to install the speed/ water temperature and depth transducer in the shower sump, which is aft. My brother thought that was a mad idea and insisted we mount it forward of the keel, the usual position. This meant we had to build this fairing.

IMG_0865

It took an extra day, but we were glad we went to the trouble of installing the depth sounder forward of the keel. It still feels wrong to drill such a big hole in the bottom of the boat!

So what’s to be done before splash?

  • Plumbing.
  • Steering.
  • Nav instruments.
  • Mount winches and blocks.
  • Metalwork
  • Ceiling lining – second fix cabin lights.
  • Antifouling.
  • Move boat ready for truck.

Two months to go.

Pressure’s on!

    Hey Pete,
    Thanks for yet another update that is just great to read and see the progress. You are a brave man putting the date in writing. We might be able to drop in at the end of October, and I’ll see if I could pull off a visit on 27/11.
    Sorry for you missing the chance for grandpa duties and travelling with Deb to Alice but I’m sure you’ll be kept in the loop while you keep soldiering on there in Port Sorrel.
    I say ‘go the milk crates’.
    John

      Hey John. Thanks for your comments. Yeah, it’s hard to not be up with the fam right now, but Facetime is a wonderful thing, and I get to talk every day. It would be great if you can make it for a visit. That’s one for the milk crates!

      Thanks Chris. It is scary to lock in a date, but for me it’s better to have a target to shoot for than just potter along. I’m really enjoying your reef series of posts. Very inspirational. Speaking of deadlines, do you have a date you need to be south of the cyclone zone?

        Hi Pete, yes we need to be south of Bundy by 1/11. We are reef hopping to see as many spots offshore as we can while the wind is light. Once we drop off our guests, whether at Townsville or Airlie we will be pushing hard to get down but hopefully by then the northerlies will be with us. At the moment it is dead calm and we are motoring!

    Thanks Dean. Yep, it’s a great feeling to be working on the finishing touches. I’ve been admiring your boat barn. Luxury! I guess you are into winter now, so hopefully, the shed will allow you to keep the boat work ticking over. All the best mate.

        Finances aside, like the grasshopper, the only “master” we boatbuilders are beholden too is time. Your loss of project time (to build the barn) will be recouped by the increased ability to control your build environment. Even in our more temperate climate here in Tas (our winter temps are around 50 degrees Fahrenheit), I estimate building outside added six months to our build, probably more. The designers estimated build time is just that – an estimate – in reality, I think a first time builder is closer to 5000 hrs. The only trap I could foresee with an inside build space is to become too comfortable. Don’t spend to much time on benches and non-essentials. That said …. I’d rather be inside! Perfectionism is the enemy of time. Built-to-plan she is plenty strong enough, and you stand a chance of getting her into the water in about three to four years. If you go for the production boat look … then ten years unless you have the finances to employ labour.

    I was just wondering, did you purchase your saloon door and from whom? Second there are fiberglass propane tanks. Light weight and impervious to salt and translucent. Worth a look.
    Cheers

      Our door is based on an aluminum security screen door. We purchased the powder-coated profile and components from a local aluminum wholesaler and assembled it ourselves. The lower infill is a piece of kitchen splash-back Russ had in his leftovers bin, and the upper is clear polycarbonate, with an H section profile to bond the two. They were riveted in place (within the channel section of the door profile) with white blind rivets. It’s suitable for our intended use, but if you are planning to cross oceans, I’d consider a stronger set-up. The big advantage of screen door components is that they are slim enough to fit seamlessly into the 24mm wide door jamb. It’s hard to find door furniture for such a thin door. Let me know if you want more details, I can send you the link to specific profile, but I imagine you would have more options in the US.
