Ultimate Cataraft Grand Frame??

Looking to modify my 16' Cat Grand Canyon Frame..... Its a big frame - 72"W x 120"L and has been modified some.

I am looking for ideas on how to haul rocket boxes. Current solution is a dropbag with a table over the top. However i'd like to add rocket boxes in the rowing compartment. Thoughts on how to secure?

Any photos of well thought out frames are really appreciated!

I like this raft setup as I rowed one of these last March... Any thoughts on bays versus no bays?

If you have nrs you can run two spreader bars about 15" apart and strap from the handles around the spreader bars back to the handles. An additional strap around the can will let you tension the first strap tight enough the shouldnt move. If you go this route then grind off any sharp edges on the cans. You probably want to put a solid floor as the space between the bars could pose an entrapment hazard

My plan is to to make custom webbing and run my 5gal military plastic jerry cans in the space there against the tubes. Much gentler on my body if i get thrashed around in my rower cage.

I'm working on my 18' aire cat frame. Same size as you mentioned. Now that the river sauna is done, I got some ideas for the frame. One goal is to provide a passenger area up front with provisions for Keeping them dry as possible for our December grand trip. Maybe also have an alternative seat behind the oarsman, we'll see. I'll keep you posted.

How many passengers are you taking? Sounds kind of ambitious as passengers eat up a lot of space and weight on the boat. Is this an 18' lion? 27.5" tubes?

Aire leopard 26.5" tubes. One passenger on board. Ever heard of mounting two above frame flip seats and having two sets of oars? Sure some coordination would be needed but on the flat water and minor rapids of the grand the "passenger" would be able to oar a little and stay warm. On major rapids only one set of oars would be used. Kinda like a Viking cataraft. Where can I get one of those helmets with the horns sticking out.
The passenger really only needs leg room if he's in a flip seat. Gear under his seat would be there anyways.
For front row seating I'd prefer him to be lower, ie sitting at frame height, that way he'd be easier to protect from splashing. I can see fabricating an enclosure in which his legs and feet were in which was water tight, sort of like a "side car" (self bailing) on a motorcycle but placed front row and center in the cat. A collapsible "wind shield" (fabric or aluminum) would be used for light to medium waves.
The most frequent comment I've gotten about winter gandtrips is that it's really cold for the passenger. I'm trying to do what I can to keep him warmer and happier. We'll both be in goretex dry suits.
A Viking style cataraft.........am I a geniuses or what?

Makes sense you need four oars anyhow may as well move the towers and do two sets. Face each other and you get the advantage of opposing muscle groups and you can converse. Also rotate the boat 180 and work the othe muscles.

A true viking ship would have a min of four rowers, eight oars.

A drysuit on the passenger and they are not gonna be warm enough? I would have guessed water temps 45 and air temps close to 50? And fleece inside the suit?

How about some vinyl rain pants over the passenger's legs? Stop evaporative cooling off the Goretex. It wouldn't be able to breathe, but I'm guessing sweat won't be a huge issue.

x2 on what Avatard said about fleece inside the suit?!

Wear fleece inside the suit. I thought everyone did that?

50F is a tough temp. Just a bit too cool for polypro and a bit too warm for fleece. Maybe 2 layers of polypro--one lightweight, one heavyweight, or lightweight polypro + very thin fleece?

I like just polypro under my drysuit in the high 50's-low 60's; 30's-40's are solid fleece temps, depending on exertion/expected immersion.

....and a neoprene beanie or hood under the passenger's helmet will also help regulate temps.
