ADDING ANOTHER JAMMER

[DAVID STRONG]

I would like to add a third spinlok jammer to the portside of my Hunter 340, there are 3 on the starboard side .Its for a spinnaker halyard so will need to be secure,can any one tell me if there is a plate (maybe alluminium)beneath the deck to drill and tap for fitting?Any help appreciated I did a search in archives but nothing found.

Just did this and there is a plate but...

...I had to drill new holes for the existing double clutch to make room to add a single alongside. There is the standard 1/4 inch thick plate under the entire raised mounting surface. Just drill and tap the new holes, seal the old holes, and mount the clutches. Should have done it years ago...
