Mounting hardware on the transom

[s2sailorlis]

This may sound like a stupid question, but how do we mount something on our lovely CD transom that would result in the object being at a 90 degree angle to the waterline. Specifically I am referring to the installation of a d-ring.

My new summer location requires the attachment of two "lovely" d-rings in order to accomodate the Frog Hooks.

- 1st picture is what the FrogHooks look like.
- 2nd picture is an example of a d-ring attached to a SeaSprite 23 - that person chose to mount on the hull side just foreward the transom (not very attractive looking...).

I rigged a simulated set up of a d-ring mounted at a 30 degree angle and the dock with frog hook (oh what one can do with plywood and some screws....). In my tests so far, the hook does not easily fit into the d-ring - too many variables of angle, etc...it could work but I would rather not drill lots of test holes into my transom...

Now I know I can mount the d-ring on a block of teak that is cut at a 30 degree angle making the ring parallel to the dock and at a right angle to the waterline. But how do i deal with the backing plate and more specifically the threaded portion of the d-ring that is now an an "off angle" and hence I cannot tighten the nut flush to the backing plate. Note I am using G10 as a backing plate. Maybe i can cut a mirror image of the exterior teak block and use as a bakcing plate to deal with the angle issue?

Thx!

That would be the best way. You could make some skewed 30 degree shims to go under the nuts.

Your mirror image block would work or you could use thickened epoxy to create flat spots on the inside of the transom at both d-rings. You could make a mold out of cardboard or luan, tape it in place, and fill it with epoxy (wax the inside of the luan first to make it easier to remove). Then still use the G10 as a backing plate against the now flat surface. Just another option...

Thanks Tim, that seems to be best option.

Thanks, I thought I had some white oak around to make larger plates​.

Will post some pix when I start the project..

Posting an update here..if anyone was interested...

I have completed the mounting the d-rings to what was once a lovely transom...backing plates were made from g10... overkill for this application but wante to try it anyway. Material used for block was Brazilian mahogany, cut at 30 degree angle.

Also a picture of my new summer home.

Looks good!!
You could rename the boat "Eye Brow" and incorporate them at each end
