Since I've made it a standard practice to bring a GPS unit with me, mounting it on a nearby thwart for non WW cruises makes it far more useful to me.
Mounting my devices has been accomplished by using a clamp on system from RAM Mounts. It has worked pretty well but the clamp/device combo is quite a bulky package.

My first stab at shrinking the load was to simply mount a ball on the thwart and eliminate the large clamping unit. This worked quite well, but I worried about having permanently mounted items which are higher than the gunnels. Rack accidents while loading came first to mind.

Happening to visit their site one day I discovered a magnetic mounting option for their product line.

That got me thinking about how to adapt that to a canoe and it struck me that for wood thwarted canoes I simply need a iron plate attached to thwart.

After doing some research, I happened on magnetic car mounts for cell phones which include thin magnetically receptive plates that are glued to the phones. During sea trials on a 4 day, 3 night overnighter I used this mounting system and it performed quite well. I discovered I could easily pick up the GPS and look at it closely but immediately and securely return it to the mount. However, the 3M glue used on the plate failed on day 3 from too much water intrusion, it was a rainy 4 days.
Some months later, after a couple of failed other attachment techniques, I settled on epoxying the magnetically receptive plate to the thwart. It required removing all the 3 M adhesive from the plate and roughing up the plate to receive the epoxy, but it seems to have worked out well. Awaiting first sea trial with copious water on the plate.
