I know the AIRE Sabertooth is marketed/pushed as an R2 boat but is anyone running frames on them (or on similar craft) for use with conventional oars? I'm thinking this would make a great sort of compromise craft - sort of a cross between a raft and cataraft in some regards. Some of the benefits of a raft, but some of the performance attributes of a cataraft in some regards. Any input? I've always leaned towards catarafts but....trying to keep an open mind here. I notice the waterline is longer (per specs on their website?) than their 13' Wave Destroyer tubes, but they have a somewhat similar "kick."
