Flush mount or bracket for GPS?

Just about to install a Garmin chartplotter on my new rib. Was thinking about flush mounting it for the sake of neatest appearance and also no need to remove it before putting console cover on, and wires will be hidden.... but that was until I broke the identical model on my parents 19 foot motor boat at the weekend. I basically came off the top of a big wave and the whole boat shuddered violently and the GPS suddenly lost the ability to pick up satelites. Seems to be alright after a night off, but I guess I'll be doing the same in my rib soon

So the question is.... is a flush mounted plotter going to be more prone to vibration and shocks than say one on a bracket mount which does at least have a very slight amount of wobbleness to absorb hard knocks? Anyone else managed to break a GPS?

I've had a flush mounted GPS on both my RIBS with no problem due to shocks. Just more difficult getting it off for the winter. Less likely to drop it though! On balance, quite happy with it fixed.

However, a word of warning, I've had two Garmin 182's over the past 2 years leak.... and I now know why.
The instructions to flush mount that Garmin give you, tell you to screw through the console into the metal screw threads in the unit. That's fine but these threads are positioned in a slightly recessed part of the unit. No problem with a bracket mount but when you tighten up on the flush mount version, you are effectively pulling the metal threads away from the unit. In mine, that caused cracks in the plastic around those metal fittings, which leaked.
I've now got round the problem by placing a stainless steel washer on top of the metal threads. They are almost the same thickness as the plastic recess and they stop the pressure on the plastic.

Incidentally, Garmin were as always immeasurably helpful and replaced both units under warranty. New one works fine.

Just one point worth thinking about.
If your flush mounted unit (GPS, Sounder, VHF etc.) gives up the ghost and you need to replace it, you will have a devil of a job to find something that fits the hole. I know that you would normaly go for the same model, but if it is no longer available you will have to go for a bigger unit or fit a blanking plate.
I have this problem with my VHF which will have to be replaced this winter, if not sooner.
Plea to electronics manufacturers - "Please, please come up with a series of standard mountings."

What VHF do you have now and why will you be considering replacing it?

Its an old Navicom/Simrad Axis 1400 and the elememts are finally taking their toll. No real problem, just old age, bit like me.

Hi

I tend to go with the bracket mount.

This makes it a lot easy'er to read in the sun light (Not a real problem this summer), when you can change the angle of the unit.

Go bracket go

Brackets

need to be careful with brackets on a RIB - if you get thrown onto one they can be very sharp and painful!

Thanks for the tips. I hadn't considered the angle thing. Chances are it won't be optimum and is likely to reflect the sun more often than not.

I cant say ive had a problem with my raymarine reflecting sunlight yet.
Ive flush mounted, one of the reasons being i dont want to carry it around with me whenever i leave the boat.
