In the past I have read favorable comments from owners of those basic Sea Eagle kayaks. The people were happy with them. If you want one that paddles faster and tracks better and theoretically should last longer, Sea Eagle makes some better models like the FastTrack and the PaddleSki. But if you just want something basic and affordable to start with, that 370 should give you a decent experience IMO. Be advised that there are one or two internet dealers who'll sell most of Sea Eagle's kayaks for $50 or $100 less than Sea Eagle themselves, and it's simply drop shipped from Sea Eagle when they put in the order for you. Like this one:
No real downside to saving a few bucks on one of these.
I was looking hard this spring at getting either an SE9 and trolling motor or a FishSup. In the end I chose to buy a Vilano Navigator sup on Amazon and a Deluxe High Seat (about 10" sitting height) from Sea Eagle, and powering it myself.
I can stand up and paddle, sit and use a kayak paddle, or sit and use a canoe paddle. I took it out earlier this month on a few small lakes and on Lake Michigan, and I was surprised to discover that the (48" overall length) wooden canoe paddle was more fun and more effective for me to use than the yak paddle. The 30" wide sup lets me get the paddle vertical in the water without a need to lean over; this would never work on an inflatable kayak that has wide side tubes. It was nice to be able to stand awhile, then sit awhile, then stand awhile, etc. whereas in my previous two kayaks I never felt secure standing up and I'd get too stiff from sitting for too long. I wholeheartedly recommend the deluxe seats; they are very comfortable and give great back support (which my previous kayaks lacked).
