Painting the hulls – Scrape • Sand • Paint

Leave a comment

 

Well, I have finally done it. I’ve gone and painted my topsides.
And prepped my hull for a new generation of anti-foul.

This is a major milestone for me. Tiare has needed a hull repaint for a number of years, slowly becoming a little more drab with each small knock the tender makes on the side, and with the passing of time wearing thin the top-paint.

Now that she is on the hard, and I have access to some high quality and affordable paints, along with the time to spend on doing the preparation work. It feels good to take my time to do it right.

This was my first repaint and a steep learning curve, I  definitely acquired some new skills. Paint scraping is an art, sanding and painting is a trade.

Doing it right means I take all the old anti-fouling off, scrape and sand back to the hull’s base coat, and then apply several layers of super smooth epoxy coating before a final coat of a modern super slippery, long lasting anti-foul.
I have not yet decided on the final anti-fouling system, there are a few options available but I will make that decision closer to when I re-slip Tiare.

Took longer then I had anticipated, as my hands seized up daily after four to five hours due to  Carpal tunnel syndrome.
If you’re my age, and a tradie, you’ll know what I mean. If you’re reading this and you’re young, look after your hands!! Waking up every night at 2am, with your arms and hands on fire gets tiring real quick.
So although one hull side would take around 18 – 20 hours total to scrape clean, it would actually take around 5 days. And there are four sides!
Fortunately, we have an onsen/spa (hot baths) close by, a soak after a day of scraping felt really good and made the CTS manageable.

I didn’t do a roll and tip, as that really only works well with paints that are thinned out. Thinning out a paint reduces its gloss and you need to put more coats on to make up the thickness.
What I did was a coach or carriage style as it allowed me to put on just four thick un-thinned coats of top paint.
I wasn’t going for a mirror finish, as that takes considerably more effort in sanding and preparation, I think my hands would have failed if I had tried, and then there is the stress over the final application of the top coats.
What I wanted was multiple coats of solid un-thinned top paint of at least 3 coats (I ended up with four coats).
I am very happy with the results.

Marine Paints from CMP

For the epoxy primers and the top-sides finish coat, I have used CMP (Chugoku Marine Paints) here from Japan.
One of the deciding factors on using CMP was that they make their paint AND catalysers here in Japan.
When I order the paint it usually takes a week or so as they make it to order, it arrives very fresh 🙂 All 4kgs or 18kgs of it.
It is also inexpensive, e.g. 4kg of white is 6000¥ ~ 60 USD for a quality two-part urethane, with the top end Fluorex Finish at twice the price at around 12,000¥ ~ 110USD.
18Kg of epoxy primer, Bannoh 1500, was 12,000¥ ~ 110USD. 18 kg did four coats below the water line.

Playing with acid

 

Now Tiare is out of the water, I take  down our Sillette Sonic Drives to replace the anodes, bellows, shaft seals and clean and fill the corrosion pitting on the lower legs, then give acid washing a go before acid etching  and a repaint.

Last winter I discovered that the SB side leg had water getting into the shaft so hoping it was just the shaft seals that needed replacing.

The PS leg pins were getting sloppy in their brackets, the answer was to fit some steel sleeves into them. Along with adding some high wear aluminum epoxy, to replace what the corrosion had eaten away around the pins.

And finally, time to grind off the 5 year old bitumen I had put on in Malaysia, and give the legs a good clean and fill up the bad pitting. Replacing grungy black/brown with a nice bright white.

Catch up Time – Ep17

Well it has been a few months since the last video.
Quite a few things have happened. Winter has gone, Spring has been and gone and we are now into the rainy season.
Sam our eldest son is now in living in Japan, Tom has gone up to Hokkaido for six months as an IT intern. And Tiare our 55 foot Wharram sailing catamaran was hauled (dragged) out and ready for a 12 month maintenance and makeover.
There is a very long list of jobs.

Would have liked to take more video of Tiare as she was hauled out but totally forgot about the video until she was out. Shame.

Episode Thirteen – Catamaran or Monohull?

1 Comment

 

This week I go over some of the myths and questions about Catamaran compared to Monohull sailboats. Based on my own experiences living and sailing on both.

Questions asked
1 • COST more $$$
2 • NEW KID on the block?
3 • Cant SAIL upwind
4 • Can’t handle the WEIGHT
5 • In marinas = $$$
6 • Maintenance are 2 X $$$
7 • CAPZISE!
8 • Motion … BAD
9 • Downright UGLY!
10• ARE more Comfortable

Episode 13
Cat or Mono

Are Catamarans faster?
Are Monohulls more traditional and romantic?
Are Catamarans more expensive to buy and maintain?
Are Cats nothing but a modern floating apartment block or the safest way to cross an ocean?
Can a Catamaran out sail a monohull upwind?
Self-righting, sinking or floating?
Opinions are based experience cruising/living on both a monohull when I was younger and on a catamaran with my family, as well as working on both as a tradie doing repairs for others.

I’m not talking high performance or racing boats but cruising, safe passage-making, live-aboard i.e. Cruising boats for everyday folk.
Nor am I talking about the big sparkly new ones either, although a lot of what I say covers them.

Obviously not all mono or cats(multihulls) are the same, different markets, price ranges, performance and comfort levels, and underwater profiles. But am happy to over simplify and make broad a generalisation to prove my point.

Episode Eleven – Engine out!

 

As usual with a Wharram catamaran this is not complicated.
With a few basic tools, a simple homemade (boatmade) tripod and one of the mainsail blocks, plus plenty of humour, it makes for an enjoyable day, well at least for me !

Taiga helps me pull out the motor and the Beast add his muscle to get the motor onto the cockpit table so I can work on her over the next month.

Main reason to pull the motors out is to install better sound insulation in the engine bays, redo the electrical cables on and around the motor and also move the instruments to a new location.

Engine is a Kubota 3 cylinder 24 Hp, marinized by Diecon and weighs around 120kg or 264lb. Enough to make it a three person job.

Also SV Freelancer drop by on their way out of Japan. Nick and Rika spent a few days here in Yuge and we introduced them to Yuge Island and of course the sun shined 🙂

Next weeks video will be a “Introduction” or “About us” type of video, not decided.

Episode Ten – Another catamaran beached!

 

This years winter projects and beaching a power catamaran.

I go over what I hope to achieve over the next four or five months aboard Tiare as I get her ready for another season in Japan.

Australian cruising friend Graham visits Yuge Island and beaches his Malcolm Tennant power catamaran for a prop clean.
Beautiful clear day with light winds along with a good tide window make it a great opportunity.

Trying to find my “style” in video. Pushing myself for weekly uploads to force myself to learn the video, editing and organisational skills needed to make this work.
I’m still treating this as a diary for myself and my kids to look back on. yes its edited, so not “real” but it is as real as it’s going to get given the public nature of it, still, I hope to show a little of who I am.
