So, here's the solution I came-up with for storage of push pole, 2 4-foot spud poles, 2 7-foot spud poles, and paddles. We'll see how well they work this Winter. Good thing is, they can all be released or secured with one hand......regardless of the velcro straps that keep them from clanking around in the boat when you're trying to slip-in somewhere quietly.

The spud pole holders were made from a 10' stick of 1-1/4" PVC electrical conduit - I have about 8' left over. Tools used were a porta-band, a skill saw, a drill, a file, 3/8" countersink bit, and assorted drill bits and attachment hardware. Don't attempt these 'cuts' with a skill saw unless you are (or were at one time) a carpenter with a minimum of 15 years experience - you could end-up missing a few fingers.
The 'T' rests in the pvc sleeve bolted to the storage box........(the black patch is EPDM rubber to deaden any noise & protect paint).......

..........and the shanks lock in the pvc clips mounted to a 1-1/2" square aluminum tube cut to fit on the diagonal portion of the crossrib brace.

I get obsessed with little projects like this, but this solution should sure make outings more pleasant.
10' x 1-1/4" PVC conduit - $3.97 + tax
Assorted screws, washers, & nuts - around $2
1-1/2" square Aluminum tubing - 'scrap'
A cold, still morning idling quietly through the timber - Priceless.
