Replacing the Windows

It has been a busy summer, so I’m not catching up on the blog posts!  This was from a few months ago, sorry!

The windows in Hurry On upon receipt were a sight.  Fogged, cracked, and keeping very little water out.  They needed replacement.  When I started this blog I hoped it would be a useful resource to those in the same figurative boat as myself, and perhaps some useful ‘how-to’s here and there.  I didn’t think of it at the time, but my mistakes, and false assumptions, may also provide a valuable insight; A ‘how-not-to’ if you will.

The following is a ‘how-not-to’.

The windows on Indy were nice, small, with easy to manage aluminum frames.  Hurry on, and all C&C 27 Mk5s are what are known as ‘floating’  They are basically held in place by adhesive only.  A number of owners I had read about used screws to hold them in, but I decided to go the purist route.  According to common convention one of the most important bits of this job is getting the surface clean.  This was the worst part of the job.  The old adhesive was like concrete, which couldn’t be scraped, or cut away, and was very stubborn when met with a palm sander.  I finally borrowed a Dremel-style rotary tool, and the powerful little sanding drum chewed through the old stuff, but it was still a very laborious task, and the drum ate through fiberglass just as easily as the hard glue, probably easier.

After the openings were cleaned out the area around the window was masked with frog tape.  I love that tape.

I had new pieces of Lexan cut out at Island Auto Glass using the old windows as a template, although beveled the edge myself.  This was easily done with a hand router and a 45° bit.

I should mention that up until this point, I think everything was done correctly.

I read about many people singing the praises of Sikaflex 295UV so this is what I went with.

MISTAKE 1 – This is a two part system.  Sikafex requires a very expensive primer which in my infinite wisdom decided not to use.

Whenever my brother is in town visiting, I always put him to work.  I got him to rough up the edges of the Lexan.

MISTAKE 2I got him to pretty much take some sand paper and basically take the shine off the edge.  I now realize the sticking power would have been greatly increased, had we done a proper roughing up with a rasp.

I filled the frame with goo, and stuck the panes in.  Then the mechanical supports were put in place which were pieces of 2X4 strategically notched and angled. They were then weighted down with sand from the kids’ sandbox.

When someone is going to be taking pics of a project you are working on, I can not stress the importance of wearing a belt.

I then took my finger and wiped off all the excess from the outside, Ray got the inside.

MISTAKE 3 – I removed the supports after a few hours.  I really should have let it cure while supported for a few days.

I’m not going to lie, after the clean up, the new windows looked goddamned incredible.

It was less than a week, I could see air pockets starting to form.  The real bugger about windows from the C&C27 Mk5 is that they are curved, not straight.  So the forward and aft sides are constantly trying top pull away from the corners.  After a few months (tonight) I went ahead and screwed them in, admitting defeat.

Window Pains

I am 36 years old.  One learns much about ones self after 36 years.  Yet somehow, after 36 years, I am still astonishingly able to under estimate how much time, elbow grease, frustration and cursing will go into any given project.  Astoundingly, I am able to look at a job and consistently tell myself “Shouldn’t be too bad”, and believe myself, despite this having never been the case.

There is a certain amount of hyperbole here, but changing Indy’s foggy, leaky windows would fall into this category.  The only difference being, I was expecting this to be a tough job.  Once again, my expectations were exceeded.

Many people with 30 year old sailboats with original windows, will tell you they look like this.

All of Indy’s windows looked like this, opaque, with a crusty grey spline, and water marks on the inside where the rain and sea had made its way in over the years.

Before removing all of the windows, I thought I would test out my process on the front port side window.  It came off quite easily, and was easy to see where the water was getting in …everywhere!

Dirt and Caulk

A knife with a fresh razor blade was able to get rid of the old sealant, and a quick rub with some sand paper to clean up any residue, and get a nice rough surface to which the new sealant could adhere.

The foam adhesive strip had perished and was pretty easy to pop the old pane out of the frame.  The strip was a bit more difficult to remove from the frame, but a few blasts with the heat gun, and it pulled off by hand cleanly.

There is going to be a lot of caulking on the inside of the frame, try to cajole an assistant into scraping this stuff off.

Those of us with Tanzer 22s will be happy to know that there is a place where you can still get Tanzer parts, despite the fact that the model is no longer being produced.  The folks at tanzerboatparts.com are quite quick to respond to inquiries, and eager to answer questions.  I had asked about replacement foam strip and rubber spline, and was pretty pumped to discover they carried it.  However, for 25 feet, which is necessary for all 6 windows, we would be in the neighbourhood of $140.

Fulfilling my duty, (my duty of being a cheap bastard), I decided to check out the local window and door makers here in Cape Breton to see if they had anything I could use in its stead.  Most told me they see a lot of boat and camper people coming in with the same plight, leaky windows, and could only offer advice on how to caulk it instead of using spline.  As anyone who has ever seen my bathroom can attest, caulking is not one of my strong suits.  The search continued.

Finally, Gary at Cape Breton Glass, gave me a 5 foot piece of black spline to see if I could jam it in the grove enough to make it work.  The problem with most of the splines carried by local shops, was that it was too robust, and couldn’t squeeze in.  It fit! (with lots of pushing and swearing).

He also gave me a roll of adhesive foam stip that was a bit wide, but with some carefully placed slits, it managed to round the curve of the windows.   In the end 30′ of spline and strip cost $14

Next I needed new panes.   Gary told me that since I was going to be cutting the panes with a jig saw as opposed to a band saw, I may need Lexan which is reputed as being virtually indestructible.  Arriving at the hardware store, I found that Lexan cost twice as much as the next brand, so once again, I cheaped out and went generic.  “Frig it, I’ll be gentle”  I remember foolishly telling myself.  90 minutes later I was back at the store buying the Lexan.

I was only a few inches in when I felt the plexi cracking apart under the tape. Lesson learned.

After gingerly setting the Lexan into the frame, I found a comfortable chair, poured a rum and coke, turned on an episode of Red Dwarf, and settled in for what I figured was going to be at least a half hour of grunting and pushing that spline into the grove.  But I was wrong.  It was a full hour.

 Slowly, I’ve begun the process with the rest of the windows, and now half are done.  Unfortunately they will have to wait until the spring to go in.  3M 4200, which is the recommended sealant, needs to be applied in temperatures higher than 4°, which doesn’t happen in December in Cape Breton.  Hopefully the tarp will keep the insides of Indy somewhat dry over the winter.  And hopefully I finish the rest of the windows by April!
