Why drill holes ??
Hi Mark :On Winpipe (B361) I dealt with this issue a bit "creativly".We have an Autohelm 6000 unit & it has a handheld extention control. When we commisioned the boat, I had the handheld unit & it's plastic holder mounted just inside the companionway entry, to the port side.As this handheld unit has a digital readout for depth, wind, etc, I bought a second plastic storage holder for it, to be used as a secondary control holder for the cockpit.I then bought a small "sticky bag" (those blue plastic mesh bags with the suction cups) & cut off the blue bag part, leaving the white plastic part with the suction cups.It was an easy thing to just fasten the white plastic sticky bag part with it's suction cups to the back of the autohelm remote control holder.So now, when we go sailing & I want to keep an eye on the depth, but also want to recline as we go (as I suspect many of us do) I just stick the suction cup holder out on the bulkhead & place the handheld control into it, set to display the depth.As I also like to keep an eye on our position & speed too, I adjust our little Garmin GPS (176C) that's mounted on it's small extention arm (fastened to the stainless binicle hand-hold) to face me & this allows me to monitor depth, speed & position as we sail along...while I'm relaxing & enjoying the ride with a sasparilla.

Best of all...no holes were drilled in the boat.
