Top Lift

Tom Cravin passed along this helpful image of a Top Lift for the Jib boom. Try this modification out, it could make the difference.

Here is a Snapshot of the jib pivot.   Sorry for the quality, but I think you can make out the important features.

You can see how much lower the jib is using this system than the standard arrangement.  Also, the rearward position of the pivot moves the axis of rotation closer to the center of effort of the sail as well as the center of mass of the sail making the sail swing out into a wing and wing arrangement much easier.

The pivot is a ball bearing fishing swivel.  I bought a box of 5 of them for 3 bucks or something like that. I drilled a hole in the deck and tied the swivel to a bar below deck that is pulled up flush to the bottom side of the deck.  I moved the pivot point on the boom rearward as well. The forward hole of the new pivot location is the rear hole of the original position, so i only had to drill one new hole.

Ballast-converts from metric to 3LBs 12oz.  I now use 3lbs 15oz and find faster speed in all winds, also use only #8 buckshot and pour small amounts of Probond wood glue over the shot over a 3 or 4 day period as it will run around all the shot and keep it all tight.  When it looks like its about all run in after a few days to dry,  I put a final coat across the top to seal it.

When I was building my boat, I chose to use the Futaba s3801 Sail servo.   This servo is much bigger than the standard servo that the servo tray was designed for, so it did not fit in the space that was designed to hold the sail servo.  I mounted the servo into the receiver box part of the tray.  I purchased some 1/2" by 1/4" wood from my local hobby shop and fabricated servo mounting points on the front and rear of the receiver box.  I then mounted the servo to the tray with standard servo screws as shown in the picture.

There is still plenty of room in the receiver tray for the receiver.  The old sail servo mount structure is just about the right size for the square 4.8V battery pack that came with my radio.  With a very small modification, I was able to put my battery in there.  This also helps to keep the boat balanced.  Because the sail servo is on the opposite side from the original design, the jib sheet turning clip on the rudder cross member should also be switched to the other side (from starboard to port) to prevent the servo and the jib sheet from getting tangled.  This is a toss-up because the rudder arm is on the port side so there is less room, but I think it is less likely to snag by switching the turning clip to the other side.

The correct Fairwind sail adjustment is when the end of the jib boom is on or at the edge of the deck when all sails are drawn in tight. The main should be off the back corner of the transom.

(Rick:  I like to be able to pull the main into the center of the boat.  So I start off my sail adjustment with the end of the jib boom pointing at the side stays and the main pulled tight to the center.)

I have the Futaba S125 sail arm servo. I had to replace the gear set 3 times because of stripping. In heavy winds the force created by the wind against the servo causes the screw holding the white round piece to come loose. This allowed for a slight movement up-down of the white piece, eventually being able to go around the square boss of the servo rounding off the edges and making it worthless.

I tried:
1- Adding a washer, no luck.
2- Adding a washer and locktite to the screw, worked for a while, but it happened again.
3- Making a new white piece with only 4 sides Vs 8 where it mates to the square boss.
It works great and to date no problem in all kinds of wind.

It took about 2 hours of handy grinding as I only have a hand held Dremel.
With a bench press it would take all but 10 minutes. I used a chunk of white nylon and shaped it by hand. I used a .039" drill bit on the corners and moved towards the center. Then with a small chisel and hobby knife remove the material.

 


 FYI: My blue pontoon boat is about a yard long and 12" wide.
