I am assuming that you wish to fish from the boat, so I would highly recommend you do not purchase anything by Sevylor or Intex. Hate to diss an entire company, but I have yet to see a product from either one that would be suitable for fishing with kids, mainly due to durability and quality (and hook resistance !) of material. I actually own an inflatable kayak from each and a Mariner 3 that was an acquisition in a Craigslist package that included a Sea Eagle 330 kayak that I was actually after.
The Mariner has a decent rigid floor and ability to mount a small trolling motor, but again, I am not confident that it would be a good choice for anyone other than a really careful and concientious adult, even then, I would plan on getting real good at finding and patching pinholes. Thank you for the info .As a matter of fact I was looking at the Sea Eagle line of inflatables.the size would be right and you info on them being durable fits .I was looking a a semi V aluminum but I,m not young will have to do it all myself haven’t looked about trailing yet
I will however, HIGHLY recommend the entire line of Sea Eagle products, if your budget allows.
I have 4 of their products, fish out of all (though very rarely out of the kayak) and I don't worry about durability in the least..... have yet to "patch" any of them and they get used frequently. My #1 285fpb and I have done quite a bit of fishing in Class ll & lll rivers and brushy, rocky shorelines in mountain lakes and reservoirs....no prob.
Again, if your budget allows, can't beat Sea Eagle, imo. Their various configurations can accommodate several anglers. You already know this, since you are going for an inflatable already, but transport and storage are a snap, the main reason I began acquisition in the first place.
(I don't work for them, but in a younger life, I might have liked to.... the same folks own Panther Martin ! Employee perks must be stellar !)
Be sure to check Craigslist or such(Facebook ?) for used, 3 of my 4 SE boats came used from CL and after close inspection, I didn't even haggle, since the sellers were so reasonable in their asking price, in one instance, about 25¢ on the dollar !
Good luck on your quest !

I just got an Azurre Mare 11’ from Saturn Boats. It is a very well made inflatable. I have a 6hp Tohatsu and also a minn-Kota 45lb electric. Happy with both for what I use them for. A warning though, the boat is very heavy for me to move around by myself at the boat launch. Has fold up wheels but still a handful. You can check out Boatstogo.com for a good variety of boats. I used to have an Achilles 9’ and it was a great little boat but the prices have gone sky high. I also researched SeaEagle and they look pretty good. I just wanted something I could get on plane once in a while😎
