If you think your designs are working fine for the white water community watch the memorial day madness video from the lochsa and count the sotars and aire boats going down the river. If I was sauntering down the river fishing fine,for a performance white water boat, no thank you not until some updates and refinement on the workmanship.
Mostly for the consumer it is good to have choices. So I think it is time for me to explain why we do things the way we do.
It is my belief that the product should fit a relatively wide range of function. So the standard 2 man culebra does not have a lot of rocker because we wanted to be albe to use it as a self support multi day boat. Our customers tend to agree with us, because they will hike it in to do multi day river trips.
We also feel that hull speed is compromised by adding rocker. Rocker may be effective for a no load situation, but the effects are quickly negated with the extra drag on the craft caused by extra draft.
Of course you do not have to agree with this, but a simple matter of physics is the deeper a cat sinks in the water the more drag there is, and the more water that is required to run the boat. So it is my opinion that our culebra would run the low water of the Middlefork of the Salmon with more ease, than Aire's more highly rockered model. I started my river career in the Grand Canyon, then moved into Utah, and Idaho. Most of my river time is multiday adventures. I will be the first to admit that I may not fully understand the day trip perspective that this your boat offers. However I do know that it plays in the river just fine. I rest assured that I can have as much fun in my boat as you can have in yours.
There is a reason why there are fewer JPW boats on the lochsa, and that reason is just because we are not as big of a company, and we do not make as many boats. We have fewer customers in the Northwest for boats. Our Culebra main hull is made from 35 oz material. The cross tubes are made with 32 oz material. The whole boat weighs 52 lbs, and can be taken apart and shipped as luggage to your destination in Peru if you like. So If you like the concept consider buying it, if you do not consider having us change it or purchase something that is already in production. We also make things out of 40 oz material.
This reply is really for other potential customers that may want to look at our design. It sounds like you have a real nice fit for you. Thanks for the discussion. Have a lot of fun in your new Aire Boat. I know you will, because they make good craft.
