I was referencing a couple of different frames.... sorry for the confusion
frame #1, shown in video is an NRS frame, 36" tube to tube.
I started it at 40" tube to tube because that was the stock spec for some frames I was looking at buying. rowed horribly so slowly worked down to a 32" tube to tube width. That puts my oarlocks 67" apart on the cat, a 12.5' legend with 22.5" tubes.
On my 14' raft, which has a constant unchanging 40" tube to tube width, the oar towers are 66" apart. My explanation for this is cat frames extend farther outboard on the tube than do raft frames, to control tubes rolling, a non issue for raft tubes.
Once I settled at 32", I retired the NRS and had Nissen weld up one of his pieces of art. with a bow packing bar so I can trim my gear load without affecting tube rocker.
sry to thread jack!
