I love my Journey! This thing is fun, fun, fun. I'm 6'3", 200lbs, and it feels perfect. I love the many cockpit adjustments for comfort and control. I've had it on choppy lakes and even some class 2 rapids and it felt great. It is playful and pretty speedy. It has a ton of storage and is very stable. The biggest down sides are the weight (heavy) and without the rudder it can be very hard to keep from weathercocking in strong wings.
The best uses for this boat are river trips (especially camping), shorter flat water trips, lake excursions, and even shorter ocean paddles. I highly recommend the rudder and a spray skirt really helps this thing keep out the chop. You will have to work on your paddling skills, but you will feel sporty and confident while learning. A great boat to grow in, and a lot of fun. It is not a tank, but just feels like a good all around touring/day trip boat. Jackson really did a great job.
As for the boat itself:
It's roomy, as it is a tandem. Lots of leg room, room for kids, dogs, etc.. It is heavy, but its a big boat. It tracks very well, but it's a tandem, so it is really up to both paddlers and not so much a boat design issue. The hatch does not provide watertight storage.
Understand that you are not going to win a race or speed down class II's in this boat. This is primarily for flat to small choppy water. Coastal rivers and sounds are ideal.
I give it a nine because it is well suited for what it is designed for
I would recommend this to someone with a few kids, dogs, coolers, camping stuff, and whatever else you want to bring along. It's stable and rugged.
I bought it used for my wife who is 5'4" and around 110 lbs. Unfortunately it was very constricting on her legs and uncomfortable. Even though it is intended for kids and smaller adults, I would say anyone over 5'2 and 100 lbs would not fit comfortably in the boat. However, should you fit, this boat rocks! Tracks straight, light, had a decent rudder installed, was fast for the intended audience. Great boat! If you can find one on CL and you can fit, you won't be disappointed.
I can't comment on the seat, as it had a cheaper replacement seat, but judging from what I've seen on the other older WS boats, they aren't that great. Hard plastic with a nylon cover.
It's a pretty fast boat. The hull is quite wide and stable. My biggest issue was the weather cocking. On flat water, as soon as you stop paddling, it just cocks around. This is slightly annoying, but makes you keep paddling (which is a good thing).
All in all, it's a nice boat for something pushing 15-20 years old. A Cheep way to get a touring boat.
