question on cat boat tube

I have 19 inch tubes on my cataraft, length is 14 ft.

I am thinking about upgrading tube size to 22 inches same length of 14 feet or a 16 ft tube length 22 inch diameter is available.

I have been rafting for a long time. But do not feel I have the technical knowledge to calculate this. My question is will the increased tube volume be worth it as far as increased load capacity, improved performance and so forth.

would use the existing frame.

Appreciate the feedback.

Jacks plastic welding has a load/draft calculator on their website that is pretty slick. Obviously other variables like shape lay a role but it would give you some good ideas.

I think it would be worth it. Especially with a cataraft, having bigger tubes is important so your boat does not become piggish when you load it down. I pretty much want the biggest tubes I can find for a Cat after starting to use them. One down side for increased diameter means increased wind drag, however.

19" is pretty small. It seems like a good balance between speed and load is 22 to 23 inches. Are you looking to build a play boat that will sometimes carry a load or the other way around or ??

You could just go plain HUGE, and get a set of Aire Lion tubes( 25.5")?

I've often thought a set of Royal Flush Tubes would be Pretty sweet in a boat that size, Jacks Plastic stubes the ends, gives it some rocker. Sounds like you end up with sweet handling, and ability to get it down tight, low water stretches if your relatively light, then if you want to load it down for a bigger river, you have reserve boyancy from the rocker, plus the tubes are 25", and the blunt ends make it cary like a bigger boat.
Of course listening to your intended purpose probly makes sense, just get excited, new Cataraft tubes!!!!

I went from a 13'x19" Sotar to a 14'x23" it's an entirely different handling boat

Thanks for the feedback.

Talked to my frame builder and he said 16 foot 24 in tubes would work fine.

Hopefully can pull the trigger on new tubes in a week or so.

I am looking for more weight carry ability and getting the frame up a bit higher off the water.

I went from a 14 ft. X 19 inch JPW Flyer cat to a 14X22 Maravia, to a 14 X 24 Maravia. The 14X19 was a little sports car, the 14X22 was a 2-door sedan, the 14X24 was a sporty SUV. I loved the 14X24 the best......then I switched to a 14 ft. raft. I used an NRS cat frame with yokes on both the 14X22 and the 14X24. The frame fit much better on the 14X24. Better gear capacity plus able to carry a passenger easier than with a 14X22.
