lncoop: My post awhile back where I said that a mesh floor would suck was not meant to be rude or anything. In your first post you said that you haul lots of gear with your boat. I think that you will find the reduced displacement a major hindrance to hauling that much gear. I admit, I have never rowed a raft with the floor removed, but I have talked to folks that have and their stories state the same. I would imagine that after removing the bucket floor, you will have the carrying compacity of a fourteen foot cat with smallish tubes. This last summer, a friend of mine took such a cat on Deso with me and with a cooler and drybox his boat was sitting way too far into the water. My 14' raft (with retrofit "Saturn type" floor) carried about three times as much gear with no problem.
On a different note: Saturn, Baltik, Auqamarine, and Aquos are all basically the same rafts with the same funky drop stich floor. I retrofitted my 14' raft with a Baltik floor that cost me about $300. In other words, you can get the same type of floor as a Saturn from other sources. Here is a link to the Baltik floor:

The newer Saturn floors might have the upgraded leiffield valve instead of the knock-off Naru valve that the Baltik does, otherwise it's the same floor.
I think that a RMR floor might be better if you can get one, but they are lace-in. You would need to cut your floor out and add grommets for the lacing. I have retrofitted a bucket boat this way as well. It's a lot of holes to cut and a lot of grommets to smack.
