The Aqua Marina AIRCAT 335 is a sturdier 11 foot inflatable catamaran that stands out for its drop stitch bottom, reinforced PVC tubes, and real transom motor mount. It is described as far more capable than basic inflatable boats, with enough structure for a genuine gas outboard and even tube pulling, while still packing down to about 41 by 19 by 11 inches and a 52 pound hull. The main cautions are registration and licensing rules that can kick in once a motor is added, plus the usual concerns about fitting motor and fuel weight on an 11 foot inflatable. It looks like a strong compact boat if the local paperwork works out.

  • The boat includes a marine transom motor mount rated for 10hp or more, which supports using a genuine gas outboard setup.

  • The drop-stitch bottom and sturdier PVC outer tubes can provide a firmer, more rigid feel than typical pool-toy inflatables.

  • The hull identification number can be used to obtain a boat certificate for registry through the Aqua Marina website.

  • The packed hull dimensions and weight can help plan checked-luggage transport when storing or traveling with the inflatable.

  • Registration rules can vary by state and motor rating cutoffs, so motor plans may require checking local requirements before buying.

  • Adding a trolling motor can trigger boat registration and ongoing annual fees in some states, increasing total ownership cost.

  • The 11-foot size can limit how well the inflatable handles motor plus gas weight, and seam or leak issues are a concern with small inflatables.

  • Texas Parks and Wildlife reportedly rejected a hull number starting with CN-ORP as not properly imported during registration attempts.

The Newport trolling motors are also on sale: https://www.amazon.com/dp/B00VYP3...title&th=1

One of those and a 12v Lithium Marine Battery ($100-200) and you're getting around the lake/marina without paddling for under $1k. 46lb trolling motor would definitely be enough for a full boat, 55lb if you want to fight some wind/current with more confidence.

Or you slap on the cheapest 2-stroke outboard you can find and you're pulling a tube at a pace that will excite grandma.

Florida is weird about these (maybe other states). If you even put as much as a trolling motor on it, you'll have to pay to register it, and keep paying every year. Make sure you factor that into the cost.

Yeah, the state-by-state registration laws are confusing. In Washington state, if it's under 16 feet and under 10HP, it doesn't have to be registered at all (on local waters). But in Idaho, the boat has to be registered and have an Invasive Species Boat Sticker (even paddleboards require the sticker). So if this is someone's first boat, they definitely need to check the rules both for where they live and where they're taking it. Fishing licenses, too.

I believe these particular boats come with a Hull Identification Number that you put into the Aqua Marina website to get your boat certificate for registry.

Definitely a state by state thing. The reason they rate the transom for 9.9 HP and not 10 is specifically for that, as its the cutoff for lots of states rules.

I couldn't find the dimensions of the box, but here is a random Youtuber doing an unboxing (and eventually some modifications): https://youtu.be/TzcOQITBS5g?t=13

At the very start of the video, you can see the size of the box.

In cali I think once you hit 10hp you have to have a "boaters license". For cali anything with a motor is now a vessel and needs to be registered with annual tags.

would it handle the weight of motor plus gas? Sadly the 11' is limiting and so many fishermen have problems with them leaking, seams splitting. But Costco would be best if a return is needed. BTW, if you need extra room and a heavier made material, Boatstogo.com has many to choose from. I own 2 of their rafts and they are built strong with 5 year warranties. This 13' boat is going to be mine. Get out there and enjoy! http://www.boatstogo.com/13.8-inf...-sd415.asp Note that if you want to go cheap, small, but effective, the Intex Mariner 3 or Mariner 4 of which can be easily modded. Intex has the Mariner 3 blem with bimini top for $149. free shipping. Grab one!

It's nice to avoid the high markups in this space; the 11' Aqua Marina has a much better price than these: https://popboardco.com/products/r...-catamaran
