river runners have become popular due to certain needs. Not everyone wants the hot rod, end o' end, aerial beast but also not looking to be "that dude in the cruise control" (please, fellow Controllers, I come in peace). Reasons I have seen the increase in river runner production.
1. A boat that is more forgiving for beginners
2. A boat that is more forgiving for experts.
I know these are the same but the reason is it is great for newbies to have an enjoyable experience their first few times out and not upside down all the time. They tend to hate that part of our sport. For the rippers they make great all arounders that they can run moderate burl in (by NO means should they ever be called or classified as a creeker) and at the same time stop and surf a wave, toss an end and throw a loop. I have been seeing some big loops in Mambas, Diesels, yadda... Just need a bigger meaner hole is all.
Another reason is schools. Schools want an easy boat to outfit their guests in and one that will allow them a stable learning platform. This also brings us to sizes. We are all different so the manufacturer needs to produce boats that will fit their paddling clientele. Schools as of lately have been going strong and they are seeing some real big folks and an equal dose of smalls. River runners in a few sizes work great here because they are stable, easy (for most) to roll, easy to turn (shorter but buoyant and semi-planning hulls), and they can learn that first BIG life changing move we all turned upstream and did for the first time!!!!!!!!!!!!..........front surf.
I work for Dagger, I paddle the Mamba. Why? I love safety kayaking in it. Plenty of volume, tons of grab points, flattish hull to surf, I can loop it here and there or at least think I am, and I can put some gear in it.
Hope this helps.
