We are blessed with many friends who have boats. The down side of this gift is I spend a fair bit of time helping friends getting their boats ready for summer. That means Shortwave is only going to be launched this weekend.

I put on a fresh coat of VC-17 last night. A bit tricky lying under the hull and trailer but the job is done. Lynn thinks the copper coloured highlights in my hair are quite trendy. I presume it will go black shortly, hiding the gray.

Last years coat of VC-17 still looked very good. We're thinking that once every 2 years might be enough. Our lake is quite cold so we get very little scum build-up. Any comments?

We also greased the keel mechanism. Thanks to everyone who posted information and photos over the last year or so. It was most useful. I've sanded down the rudder, filled the gashes and applied epoxy to seal the wood. Tonight I'll be applying VC-17 so it matches the hull. This seemed the way to go as we leave the rudder in the water for long periods of time. The rudder cheeks above the water line will remain natural wood.

D'Arcy, you should get two years. Once you haul out in the fall, you must be careful not to wash away too much off the anti-fouling, with the power washer.

As far as the rudder is concerned, when I had my boat slipped, I used to remove my rudder after each trip, and stow it inside. An extra step at the end of the day, but I didn't want(and niether did the PO)anti fouling paint on the blade! I don't remove it if I'm sailing for several days in a row, ie like if you're at the cottage for a weekend In that case, I'd remove it before I went home.

Why it's good to help other sailors. Helping my brother rig. Mast up Friday evening, tuning Saturday morning.

The payoff: Sailing Saturday afternoon. We're on starboard tack but that's a lot of traffic to get through. Queen City Yacht Club in the background (Ken's summer home).

Eight meters maneuvering. Beautiful boats

This evening I put new sealant between the rub rails. The old sealant was brittle and crumbling. Lynn applied Cetol to the grab rails and teak trim around the hatches. She also put new gasket material around the forward hatch. Saturday morning should see us sailing out of the Village of Rosseau in Shortwave.

While D'Arcy was helping to clutter up Toronto Harbour with RCYC sailpast, :-) Queen City YC was holding our own sailpast. Note the formal sailing attire of the gentleman standing before the mast on his dockmate's Nonsuch (that's me!)

Lynn's backside is just visible under the loose-footed sail. There's no danger of getting whacked on the head if you sit up there. I kidded the skipper all day about the missing jib.

After haulout each fall ShortWave was taken to the local truckwash and scrubbed clean top & bottom with medium pressure hot water & soap. The green Lake Ontario scum stripped off nicely, leaving plenty of Teflon/copper based VC-17 on for the next year. After a few seasons experience, we recoated the anti-fouling bi-annually.

Note that I never used a consumer type power washer.It would strip off the bootstripe paint and drive water under the deck fittings...not a great idea.

Don't worry guys, we're much more casual on Shortwave. I've been wearing this blazer one day a year for the last 30 years. I used to wear it while sailing my Lazer at the Kitsilano Yacht Club sail past. It fit a little better then (It must be shrinking).

Note the neat “in mast” mainsail furling.

You two would be right at home on the cover of 'Gentleman's Quarterly'.
At one time our gang thought about a 'crew outfit' for the Mirage 33 we crewed on.
For casual wear, I always liked the white shorts/trowsers and the blue/white horizontal stripe t-shirts and a navy blue baseball style cap. I even had plans to use my 'bosun's call'to pipe our skipper aboard on special occasions. It was just a dream though, our motley crew lacked the discipline to carry it out.

That's probably us on the catboat Nonsuch in the upper left corner of D'Arcy's 1st picture

Great pictures guys!!
Is that wooden looking 8m in the forground Bangalor?? I have a picture, somewhere of it from last years NOOD They are pretty boats!

Re power washing, I couldn't agree more with you Ken. The powerful spray can be destructive! I have two types of spray wands with mine. One is the swirling head, really powerful, and another that sprays a flat pattern, and is adjustable in intensity. It can be ajusted down to a normal hose trickle. I have a well at my house, so I pretty much need to use the pressure washer all the time. The pressure washer gives me the added power I need to cleanse the boat

Thanks for the VC-17 comments. One more classic boat. If money were no object I think I could be very happy owning something like this.

BEAUTIFUL!!!!!!!!

Now, can you ID the boat, and it age?

I've seen smaller DIY kit boats called Weekender. They're gaff rigged sloops though. This baby has all kinds of sail

Thanks for posting D'Arcy

I finished the rudder. I filled all the gashes with Marine-Tex. I also built up the edges to their original shape. The middle of the blade indentations are most likely from the prop. The damaged edges are most likely from hitting various objects like rocks. The Marine-Tex is a good product sticks to anything (even wet material). You have to be very careful when mixing it though or you'll get air bubbles. I encountered a few when I sanded the filler down. Had to refill the gaps. I think epoxy filler might have worked a little better.

After sanding the filler, I applied 3 coats of epoxy. The first coat penetrates into the wood and filler, second coat covers, and the final coat will hopefully make sure I don't sand off the second when sanding before painting. Here is the rudder after being filled and coated with epoxy.

My epoxy coats ran a bit so I had a tough sanding job leveling the hardened epoxy smooth. After sanding, I applied two coats of VC-17. It's great paint but because it's such a thin coating, all my imperfections are visible.

As a guy who spends way too much time in the office, I'm not great craftsman; but I'm learning. In hindsight I should have been more thorough during the filling process. Racers who desire a super smooth surface sand and fair the surface several times. Sometimes you can see more filler than rudder! This isn't as important to us since we are casual cruisers. The rebuilt rudder will work better than before and it's now completely sealed. Should be good for another decade or so.

Great job D'Arcy!

I had a similar effect when I finished my keel this spring. A couple of spots weren't sanded as smooth as I had thought. VC-17 shows off the imperfection .

I basically did the same work to my rudder blade last year, except I went with an additional 3 coats of Cetol, followed by 3 more coats of Cetol Gloss. Since I keep the boat on the trailer, I keep the wood finish I'm sure my imperfections would show up with VC-17 though.

I figure we should likely be even in the races, with our un-faired foils

Many years ago I was at a seminar on Laser racing with Ian Bruce (Designer of the Laser) one of the speakers. Someone asked him how he would finish his rudder (wet sand, wax, etc.)

His answer was that there is so much turbulance by time the water has flowed pass the hull and centreboard that he would do nothing. He recommended that you would be better spending the time sailing.

A lot of cruising boats have the same imperfections we do on the rudder. We're spending the rest of the summer time sailing. Last weekend was great being on the water.
