For an experienced paddler:
These kayaks can be a delight to paddle on flat water. They're light, fast, and maneuver beautifully.
For an inexperienced paddler:
It'll be a nightmare. It has a K1 competition cockpit which is a tight squeeze to get into (legs in first then shuffle to get your bum in). If you have to swim out and your technique isn't perfect it'll strip all the skin off your lower legs, the same can be true just from getting in and out. The knee brace edges are bare composite, they're sharp.
It'll never go in a straight line and if you don't get the right edge on the turn it'll bite. There will also be rough patches and sharp edges asking for you to injure yourself, on an older boat like this you'll learn the joys of glass fibre rash. The fit is tight to get good control, you probably won't be able to wear shoes inside and you'll get a selection of injuries to your feet if you don't have the right callouses for it. You'll also find the seating position really quite uncomfortable for prolonged use until you adapt.
The particular boat in the image has a major repair to the nose, I'd inspect carefully to see if there's anything else. Holding it over your head to see where the light comes through can be a good start to finding real damage, but a full inspection of the hull, deck and seams will be required. Don't neglect the deck because it's normal for boats of this type to be significantly submerged when turning even on flat water.
The seat has the remains of glued on padding round the back, you'll need to clean that up or it'll be quite uncomfortable. They normally come with Badger adjustable footrests, but check it doesn't have fixed position pegs.
In short: This is not a beginner's boat, it's especially not suited to an unsupervised beginner.
