Here is some friendly advise.
1. That is one big beautiful plotter.
IMHO, too big for the boat. As you are finding it is difficult to find a suitable mounting location for a plotter that size. For your size of boat I generally recommend a 7", maybe a 9".
All modern plotters have WIFI
, so if you are visually impaired, just call it up on a 24" or larger smart TV down below.
But to each their own, this is what you have, and maybe what you want to stay with.
2. Companionway bulkhead mounting. I get paid a lot of money
every year to fill old instrument holes in bulkheads and cockpit coamings.
Wrecks the best seat in the house. Difficult to reach from behind the wheel
. Someone is always sitting in front of it. Difficult to repair if your not a glass man.
3. Swing arm in companionway. Not the best solution. During rough weather
, when you may need your plotter most, you should have you hatchboards in. where you can't see it. In good weather, the thing is always in the way for going through the companionway. Constant working on instrument connections is not good for them.
4. Mount in hatchboard. Better IMHO than swing arm. Need a bracket to hold hatchboard on back of companionway for gertting through so wires don't have to be connected/disconnected all the time. Out of reach from behind wheel
5. On deck
bracket under dodger. Forward visual block, especially a plotter that size. Out of reach from behind wheel.
6. Suspended under dodger. Good if centreline where you won't ding your head
on it. Reachable from behind wheel. Can't take dodger down (really bad weather) without losing plotter.
7. On coaming near helm
. Reachable on one tack, not so much on the other. Course orientation doesn't match boat course. (Throws some people off.) Risk of getting kicked.
8. On poop deck
or pushpit behind helm
. Twisting around to operate is a pain and possibly dangerous. Some can't convert the opposite orientation to course orientation easily.
9. In helm pod right in front of you. Best solution for most people. Easy to access. Course orientation perfect. Easily changed without wrecking boat.
I've installed a lot of instruments and have consulted a lot of people trying to avoid cost of a quality helm pod. Everyone I've convinced to go that way are happy they listened. Some of those who haven't, have been right $#^%$^ with themselves afterward, and some even $%$% with me for not pushing them even harder in the helm pod direction. ;-)
