Last post by Stu Jackson - Yesterday at 10:27:34 AMMy pedestal just sits on top of the t&h under the table, when lowered the table sits in the runners just fine.

Main Message Board / Table pedestal
Last post by ghebbns - Yesterday at 10:19:46 AMHi all,
When I bought my boat over a decade ago, the teak and holly floors needed replacing. My father and I did it ourselves, but I now realize that we should have cutout a hole in the board under the table for the table pedestal. I have always had to remove the pedestal when I lower the table to create a berth as it was too high.
Not a big deal to cut a whole in the floor board (the hole is already in the sole of the boat), but not exactly sure if the bottom of the pedestal just rests on the bottom of the boat? Basically just wondering how the pedestal typically works.
Thanks

Last post by scgunner - September 19, 2025, 05:55:31 AMTo finish off this thread I drilled out the inboard holes the depth from the top of the traveler track to the cabin ceiling in my boat is 7 3/4" so with the supplied 10" bolt I probably could have used any of the holes on the track. I cut the bolts to fit and snugged everything down, disaster averted.

Last post by awesome34 - September 11, 2025, 09:50:44 AMSince it looks like you're in San Diego, I would recommend getting a quote from Luis at LG Sails. He has a good understanding of how to maximize performance. He made my genoa and we have done well in the races with it. He made a vertically battened furling main for a friend's Beneteau as well, so he will probably have a good understanding of the trade-offs for your sail too.

I did read and reread the links and taking another look at the traveler mounting I can see that the farther out it gets the deeper it becomes. The bolts CD supplied are 10" long but you're right I don't know if that's long enough for the outer bolt and I don't want to drill a hole to find out so I'll use the inner holes as recommended.
Ken,
When it comes to Geometry I dropped the class in high school before I could fail it so I'm not exactly an expert. My thinking was for reinforcing a wider base would be better but as Stu pointed out with upward force reinforcing closer to center would be stronger however since that pulling force can be generated from just about any angle when under sail who knows where the ideal place to reinforce is. The good news is as far as I know nobody who has done the traveler upgrade has had a problem.

I'm going to go a little outside my immediate knowledge of the 34 traveler/riser/deck sections here, so I may not be 100% right on.
Forgive me Stu!
You have to drill down (ugggh) into the links in the Critical Upgrade. To get enough length to use the outside holes, John's Plan B was to use all-thread from McMaster, and countersink the Acorn nut into the traveler.
This part is in my wheelhouse.
We know the force is greatest on the fastener when the load acts verically directly above it (the vertical component of the stress is virtually 100% - no horizontal component.) ie, the boom/mainsheet blocks and car are positioned directly above the bolt, and nearly all (say 90%) of load is be transferred to that fastener.
If the boom moves left or right of that car position the vertical component on the fastener decreases and (not an issue) the horizontal increases.
That's if all things are equal in all positions on the traveller at all points of sail. Of course sail pressure and load on the car don't work that way.
So very theoretically, the optimum thru bolt location is when you'd expect the hardest mainsheet (low horizontal load, high vertical load) and the car imparting that load as equally as practical onto both fasteners.
So I tend to agree that the optimal is where the two bolts are furthest apart. Then, the stress is more equally shared between them as the vertical load is anywhere except maximum outboard.
The highest load is going to be beating with the car inboard (greater sail pressure, harder sheet so greater vertical component — the perfect storm.)
And the further apart the fasteners, the more equally will the load be shared between them.
BUT that is theory. If one fastener is way stronger than the load it could ever see, then taking 100% of the load alone makes no nevermind anyway.
It's like I say about the Sherwood pump - yes, it pumps more but if you don't need that additional capacity why put up with a crappily designed pump?
That said my propensity to over-do (and sometimes regret it) I'd probably thru-drill for two on each side and to hell with relying on the embedded plate (because it's an unknown quantity.)
(Notice - ignoring my own rule about "excess capacity"

In any case I've got the bolts necessary to do the upgrade but what I find counter-intuitive is the recommendation that the thru bolts be mounted as close to center as possible. It seems to me you'd get a better purchase mounting them as far outboard as possible.
Kevin,
It would be helpful for you to click on the Critical Upgrade link I provided and please read the two links in that first thread. The reason is that the pictures I provided show that the long bolts that I installed on my boat came through holes in the traveller track inboard of the machine screws into the plate. They also show the mistake I made of having one four holes in and the other three holes in. Turns out that didn't matter much because the one further inboard on the starboard side just got an acorn nut stuck on the inside, while the other one just barely made it deep enough to be able to put a fender washer and nut on it!
If you put the 9 inch bolts further outboard they won't be long enough.
If you get longer ones, I can't tell you enough of the geometry of the curved headliner vs. the flat traveller fiberglass to tell you if it'd work.
That's why we recommend following what has worked for others.
As far as support, no, it wouldn't make any difference, because its still the two machine screws plus the two through bolts - over that short a distance it doesn't matter what order and that thick and stiff track.

I wandered the labyrinth that is the McMaster website and while I'm sure those bolts are in there somewhere if you can find them you're a better man than me.
