The Sevylor ones are pretty good for the money. We’ve had a Colorado for a few year now, used regularly in Anglesey. Very stable, have never come close to capsizing, just bobs up and down nicely in the swell and waves.
You do have to be careful in the sea though, avoid running tides (unless in your favour) and as soon as the wind gets above 10mph or so, progress can be pretty difficult.
For that reason we’ve recently bought a Gumotex Seawave. Only given it a quick try in Coniston so far, but reckon it’ll be usuable in a wider range of weather than the Sevylor.
We’ll mostly use it as kayak though and we noticed the double paddling makes the tracking a bit more difficult, considering adding a rudder now to help with that. Never really had any tracking issues with the Sevylor, but always used single paddles, something to consider perhaps.
