Oar length for a 16' cataraft

I recently purchased a 16' cat with Maxxon pontoons (16'x22.5"). I have 8' Oars for this boat but they seem a little short. Before purchasing new oar shafts (or extensions) I want to see what would be recommended for this boat set up.

Entirely depends on frame width (oarlock-oarlock), oarlock height off the tubes, how high you are seated, types of rivers you are running, and personal preference

As a reference i have a 66" nrs frame, 22" aire tubes, 6" towers and i sit on an nrs seatbar. 9.5 feels about right for me but i personally like longer oars

I have some carlisle 1' extenders i will be selling shortly if this will help get you there

Yea, thats gona be a bit short. You want to go off frame width.

60" about 8 to 9'
66" about 9 to 10'
72" about 10' + ?

Bottom line, what ever feels good to you. I say go long cuz you can always cut down the shafts.

Note: cutting down carlisle shafts almost always involves turning down the handles with a lathe to account for the inner sleeve

Your tube diam seems kinda small for a gear boat i'm guessing you are using it for fishing trips?

I don't plan on packing a lot of gear on this boat.
1 dry box
2 large coolers
a few dry bags and some Misc. gear.

Mostly i use if for 1 night fishing trips with no major rapids.

I would set the frame up in your garage, off the ground to simulate typical frame to water clearance. The garage floor is the surface of the water. Use seat and existing shafts, no blades, and adjust the stops where they feel comfortable (some set them up wide, some put 4" gap between handles when pointed towards each other). Again. Preference

Dial in the position of the oars to what is comfortable and have a friend use a tape measure from the ends of the shaft to where it would touch the floor if it were longer, Add about 2" and then you know approx how long the shafts need to be

Then try and move the shafts through a normal range of motion and make sure its not hitting your knees etc. this might let you know your towers are too short, your seat too high, or your legs too bent

I have a 16' cat w/ 25" tubes, oarlocks are pretty much right over the frame, 8"+ oar towers, I sit on my cooler, and I love my 10.5' oars.

If your frame is 72 wide and you're sitting on a dry box, then 8 ft. oars will be too short in my opinion. Every time I've made changes in my tube size and seat height I ended up needing longer oars. I run a 14X24 Cat, 66 inch NRS frame, use a AAA flip seat over a dry box, and now have 9.5 ft. Oars.
