I’ve had a few inflatables now and think they are really good as long as you are prepared to work with their unique characteristics!
They don’t track as well as a rigid. I’ve a Gumotex with a removable skeg and it’s by far the best tracking inflatable I’ve tried but is still not as good as a rigid. I’m being really picky though. They are also a little harder to really ‘work’ as boats; by that I mean heeling them over in tight turns and using more complex strokes.
If you can I would strongly recommend a Gumotex. They are more expensive but they are much more robust than most others. Think RIB without the solid sections and you won’t be far from reality. I have a Baraka and it will do everything from lake touring to white water.
Other good brands are Advanced Elements and Z-Pro.
Sevylor are good and are fantastic value. However, be aware that some models have a thick, sturdy fabric outer to the inflation chambers. This is good in that it increases their abrasion resistance but it does mean that they are often packed away wet. Using them on a sandy beach often means the boat gets packed away wet and sandy. Boats like Gumotex don’t suffer from that problem. It’s not a big issue but we use our inflatable travelling in a camper van and it’s a godsend being able to wipe down the boat and pack it away dry.
Hope this helps.
