PSC 31 Journey
Tried to attach a couple of pix with no success, really don't have a good one, so I'll add
a couple of pro-pointers here:
You want to attach it as high as possible, my top struts are about an inch below the cap rail, I believe the manual mentions this, which brings me to the next point...
Its tough if not impossible to get up and behind to attach the nuts on the inside. What we did was just drill straight through the hull and inner liner. Then using these holes as a guide, cut openings in the inner liner, and use some starboard to cover the holes, it sounds worst then it looks. BTW, I don't have a stern swim ladder, I use the kind that hang over the side.
As mention before I have 1 set of blocks (double stack cheek block, one over on top of the other) mounted on top of the coming even with the steering wheel with some starboard cut to provide a level base. Lines go directly from the vane to the blocks, then to the wheel. You want to use only 1 set of blocks to minimize friction, important in light air conditions. Make sure you get the light air vane, I forget if that's standard or an option.
You can always untie the lines to open up the cockpit if you need to.
If you go to their website and look at their 31 pix, there is 2 kinds, Nayada is the newer design like I have, my mounting is the same as theirs, but they use 2 sets of blocks, I use 1. The older designed used 90 degree angles that required welding that would eventually fail, the newer design uses bent tubing instead, but it needs to be mounted higher.
I hope to go down to the boat this week and will try to remember to take some pictures, I should send to scanmar.
a couple of things to note about windvane usage:
1. it's a bit of an art to get it adjusted correctly, try to get the boat balanced first, if you are having a tough time steering, the vane won't be much better.
2. I've used it inshore, but the vane needs not just constant direction of wind, but also strength, wind gusts tend to cause the boat to get out of balance and pull to windward.
3. Offshore it will hold a constant coarse within a few degrees, I've literally ran directly over my way point from 50 miles away without touching the vane.
4. I've used it when motoring, as long as there is apparent wind and you don't churn the water too badly, it works fine with the light air vane, probably needs about 6-7 knts to be effective.
