Hello everyone, this is my first post in the forum. I recently picked up a 2010 TI and have been having a blast on it. The only thing I wanted to do, was try another seating position. So I came up with a mount that allowed me to attach a folding stadium seat.
Image
The seat is completely detachable, so I can go back to the original seats at any time. I used Yakattack rail mounts and a fabricated sliding mount to attach the seat.
Image
The only area that I had to put some thought into was the starboard side. The centerboard takes up almost all of the space on top of the gunwale. The best solution I found was to remove the centerboard cover and fabricate a steel plate that sits below the cover and uses the four screws to attach it to the hull.
Image
I used the steel plate as a mount for a sliding bracket to attach the forward part of the seat. A short section of Yakattack bracket was used to attach the rear part of the seat.
Image
On the port side a single 12" section of Yakattack bracket was attached to the hull in order to attach the seat.
Image
The seat mounts are two sections of 5/8" square tubing. What I ended up with is a range of about 3" of front to rear adjustment for the seat.
Image
The seat itself is fabric supported by bungees, it is pretty comfortable. I know the seating position is quite high, but I am only planning to use it while sailing, so I am not too concerned about higher CG issues. If need be, I can fabricate a drop down mount. Sorry about the huge photos, not sure how to take care of that.

Today we took the TI out on Lake Havasu to test the new seats. I had also built and installed a main sheet riser to get the main sheet out of the face of the person in the rear seat. Since the seats had been raised, I also added a 2" riser to the rudder control. All in all the modifications complimented each other. We started out with winds out of the south at about 12-13mph, they increased to 16.1 by the end of the day. I buried the downwind ama a couple of times. The only thing I noticed was the shape of the sail seemed a bit too deep, I think I may need to shorten the main sheet riser about an 1 1/2 to 2 inches. Otherwise, I absolutely loved the way it handled and the ride was high and dry, thanks in part to a spray deflector designed by Gary Meyers installed around the front cross bar. I was able to stand up easily and get to the tramps. We were out about 4 hours and the whole time it was a comfortable ride. One plus was having a large storage area directly under you. Even with the higher CG, it was worth it. Can't say enough about a comfortable ride.

I've been searching high and low for a better seating solution for my 2011 TI. I like your concept here, but I'm concerned about how sitting that high would leave both me and the wife wide open to getting sail slapped!

My wife had been complaining about the main sheet annoying her every time we tacked before I changed the seats. So I built a main sheet riser from pvc using one of the several examples in the forum. That effectively raised the line above the head of the rear seat passenger. We tried out the new seating yesterday, we both like it. It made getting up and onto the tramp easy, no wet rear ends and a lot more comfortable. The CG is higher, so I am still a bit tentative in higher winds. I tend to reef the sail quicker. But, we have only had it out one time since I put in the seats, still getting used to it.

Today I took the seat mounts apart to inspect them. I noticed a slight bow to the front seat's rear mount. That caused me to ditch the 5/8" square tube and build stronger mounts from 1"x2" rectangular tube. Now both mounts are much stronger. The rail mounts and the steel plate under the centerboard cover performed perfectly. I weigh 175 and was up and down out of the seat while we were out. The rear seat mount did not bend, but I replaced both seat mounts because the smaller tubing was not sufficient. I will post again after testing the new mounts.

Nice work on those seat mounts!
I like the use of the the rail mounts and how you solved the lack of mount space next to the centreboard. 8)
We also raised our seats and found the higher CofG wasn’t an issue. It also made hiking out on haka easier.
