aisle width in Lund SSV 16

[water bouy]

Getting ready to cut out the aisle part of the middle bench on my v hull Sea Nymph and wonder if anybody knows how wide it is on Lund SSV 16. Looks like mine needs about the same. No specs mention the width. I decided to cut down an inch or so and then brace across it with angle until everything is good and sturdy.
Pic is an 18 ft SSV.

A Lund dealer in Troutman happened to be working on a SSV 16 and said it's 15 1/2" wide. Let the chopping begin.
