The photos in this folder are of the installation of a capehorn windvane on my 
Tayana 37 PH.  This turned out to be a much more complex project than I 
expected and I was sure glad I hired Yves Gelinas (inventor of the capehorn vane) 
to install it.   Even now that I have helped him do it once, I would hire him again if I 
needed this vane installed.  Yves is a perfectionist and does not rest until the 
details suit him.  

Ill run through the photos here and annotate what is going on at each stage.  For a 
more complete understanding of how the vane works you can go to the capehorn 
website and see a lot of details.  As a matter of fact, you can even see the website 
in French. 

Picture 01:  For some reason Ta Yang felt I needed a locker on the starboard side 
of the cockpit rather than access to the machinery in the stern of the boat.  This is a 
pic of the locker I took in Taiwan before the boat shipped. I was already anticipating 
problems with the CH installation. 

Picture 02:  This is a picture of the same locker from below.  You can see how it 
blocks access to the stern.  The gold colored thing is the hydraulic ram for the pilot 
house steering.  The boat has standard whitlock cable steering from the cockpit 
and hydraulic steering from the pilothouse. 

Picture 03:  This is a view of the locker sitting on the dock in two pieces after a nice 
man named Bob took a sawsall to it for an hour.  Unfortunately it would not come 
out in one piece so my original plan of making a planter out of it had to be 
abandoned. 

Picture 04:  Shows the resulting access we got by removing the locker. 

Picture 05 shows Yves doing the thing he did most during the installation.  He's 
measuring before he drills.  Yves has taken the old addage about measure twice 
and cut once to a new level.  He measures about 10 times before he cuts. There 
were some real clearance issues in this installation and he had to make sure the 
quadrant on the inside of the boat was positioned correctly. 

Picture 06:  Shows the start of the drilling process.  Yves had me look at the drill 
from above and from the side to make sure he was aligned correctly.  It is very 
important that the vane be aligned along the axis of the boat.  It does not have to 
be in the middle but it does need to be parallel to the line of the keel.  Yves used a 
very long pilot bit which made it easy to see how well aligned it was.  He also used 
a level a lot. 

Picture  07: I did not think I was going to be able to watch this part but by the time 
Yves was ready to drill I was very sure he had it all scoped out.

Picture 08: This is a pic of Yves holding the plug that he cut out of the boat.  He 
said it was about twice as thick as the one he had cut out of a HC the day before.  

Picture 09:  The mounting tube wont fit in the hole without a little adjustment with a 
grinder.  Yves is checking for the tight spots before he starts cleaning up the hole.

Picture 10: This shows the mounting tube installed in the stern.  It was eventually 
roughened up with a grinder and epoxied in place with thickened west epoxy. 

Picture 11: Yves is down in the new hatch (former locker) installing braces that hold 
the inside of the mounting tube in place.  On some boats he glasses wood blocks 
to the hull for this purpose but on my boat he was able to tie the installation into ss 
braces that support the rudder shaft.

Picture 12: This pic is a little difficult to see but it shows the CH quadrant back 
behind the boat's steering quadrant.  I'll get a better pic of this soon.  We were 
trying to beat the weather on the day he did this part of the installation so I did not 
want to take too much time to set up photos. 

Picture 13: This shows the vane from the side with the windvane tower in place.  
Eventually braces are added to the structure to hold the tower in place. 

Picture 14:  Shows the oar (Yves calls it the "paddle" but IM having a hard time 
breaking my monitor naming habits) in place.  The size of the oar is customized for 
each boat design and its size is based on the surface area of the rudder it must 
control.  Yves pointed out that the only time paddle size is a factor is in light air and 
that I can shorten the paddle if I want without any heavy air problem.  I bought a 
spare paddle so after I have some experience sailing the boat I may tweak the 
paddle length.  I I screw up it can become the spare and Ill use the other one for 
light air. 

Picture 15: Shows the vane with the braces in place.  

Following the installation of the ss components of the system Yves spent more 
than half a day working out the leads on the line below the deck that connect the 
vane to the boat's steering.  

As soon as I get a mast on my boat and can take it sailing, Ill get some pics of the 
vane in use and let the group know how it compares with the monitor I used for 
years on my NorSea.
