You asked about Wing Inflatables, so let me explain. I don't post on MB on purpose, but I feel another useful message should go out there. After many years of commercially driving these and many other boats, it boils down to this... There are Wing boats and there's everything else. Nothing else compares my friend.
Of course people have their opinions. I've seem two guys go to blows over whether a Wing or and Avon was a better boat. Both are total drunken douche bags, but the guy who likes Wings won the fight.
They are rigid as hell, and theoretically flip easier than all the other soggy boats out there. I like that though. The closer to a kayak, the better I say. You are getting cat tubes, however. There's less performance in general with these types boats of any brand, so you'll only get to experience Wing's quality construction and perhaps some additional durability in your day. The frame bears the structural burden.
They did make boats exclusively for the military for about 8 years, but after they were a ordinary raft manufacturer. Why did they get the contract for the military you ask? Because they are bad ass boats, that's why. I hear they even started making low caliber bullet proof boats. I want one of those just to brag. Now they are back in the private world making the best and most expensive boats on the market. $1500 a tube sounds somewhere between "just about right" to "cheap" depending on their length. My buddy got his Wing tubes for a steal at $1200 each.
Hurry up and buy them before someone else does and happy boating.
