Ducky under cat for added float

Were thinking about rigging a Tandem ducky under our mid size cat for a 30 day Grand. For 450+ extra lb of floatation and to deploy for canyoneering missions that require a river shuttle. The waterline under the weight were planning is well over 33% of the tubes, so were thinking the Pro's will outweigh the cons.

Has anybody done this? We are open to criticism!

You'll enjoy your trip more with the proper equipment for what you're carrying. If you're over on your weight limit, a duckie under your boat is just going to make your heavy rig ride like shit. Drop a grand and rent a boat. You'll be so happy you did.

I would think that sticking a ducky under a Cat would seriously effect the maneuverability of the Cat, and not in a good way. Randaddy's right......rent or borrow a raft. Either that or lighten your load. But, if you do choose to try this, we want to see pictures of this rig !!!!!

Forget the ducky......I want to talk about that frame!!!!!
Interesting use of the NRS Universal drop rails to make a wider double top rail. And what on earth are those net thingies with the bars on the front and back of the frame????
I love to tinker around with NRS frame parts in new ways, but hadn't thought about that double top rail idea. I can't tell in the pictures....are you using NRS Cat yokes or the Universal drop rails for the main frame?
Ok....back to the ducky issue. Is the ducky really supporting any of the frame weight? Hard to tell in the pics, but it looks like the Cat tubes and the frame are quite a bit higher than the ducky.

bow and stern "trailer" frames can be taken off easy and are hinged because they rest on the rise of the tubes, they have AAA drop nets with zippers and usually have decks over that. w/o the extra trailer bay, the double rail, and floor we can make it a couple feet narrower.
-The ducky fits under it perfectly, its flush with the spreader bars, coolers and box. It sits even with the tubes becomes one with the rig. it looks like it will still track okay, and will add heaps of ballast for 22,000+ release next month.

Take less stuff?

I did it on my first Grand trip. A weld broke on one corner of my frame. I lashed a Lynx II under my floor to take some of the stress off the frame. The floor of my frame sits fairly high off the water and is 12 ft long with a full length diamond plate floor. The boat rowed a bit slower, but it wasn't that big a deal, especially since most rapids on the Grand require very little maneuverability. But you should probably think about taking less stuff or renting a bigger boat.

Use the ducky. If it sucks just wrap it up. As your load gets lighter you can also wrap it up.

Here are four pics of a guy i know ran Rainey falls (rogue) with his 16' jag loaded with a lot of gear

He said it worked and the extra boat helped shoulder the load

I also like the idea of the custom drop rails as a second rail but have durability concerns. The main siderails dont have contact with the tubes. Do you think under a lot of stress that the lowpros could slip or fracture? Might not be a bad idea to pin them and bring some spare lopros cause i'd hate to float the grand with mechanical issues
