Phil Herring;
If you will look at the photos on the 23.5 under boat information, you will see two grooved teak slates one on port and the other of course on starboard on the top of the cockpit coaming just aft of the companionway. Originally, they were for covers only with no holes cut in them for cup holders. Later, I do recall holes cut out for the plastic cup holder which you did advise correctly.
Can you make the teak slats with holes for the plastic cup holders for this fellow. I do not have the deminisions nor am I near a 23.5. Sorry about that sir. I hope this helps you.
Hercguy:
Take a photo so Phil Herring will see what I think you are talking about and post to this thread.
Thank you to Phil and Hercguy.
