I've been surfing on sit on tops for 4 years and the Perception 5-0 is the only truly surf capable sit-on top I've had the pleasure to use.
What is good: This kayak performs like a wave-ski in medium to large surf. The quality of the fittings and the finish are great. In fact this is the only sit-on top on the market whose fittings are safely up to the job of rolling in big surf!
What is not so good: The 5-0 is slow on flat water, but that is not the point – it is a surf-orientated craft. However, it is big and heavy (20 kilos) and is overkill for someone my size (10 stone and 5'7"), probably more suited to the heavier paddler.
Summary: the best sit-on top for surf there is, but why oh why don't Perception design a scaled down model for smaller paddlers?
well built molded ski. owned for 2 years and given me many a fun session. handles any wave above 3 foot including steep east coast scotland faces 12 foot +. pretty stable and reasonable at getting out back. fairly slow to paddle compared to some but that's to be expected with a ski this size, weight that sits low in the water. once on the wave it turns well and holds the face.
I've tried cobra strike/island lipstick, bigstick and grp composite skis. this may not be as light or fast as composites but i would rate it above the rest. its easy to paddle and more stable if your starting out, its also made of tough material, the foot plate is good and the thigh straps work well, although never broke fin was always paranoid i might as it has a delicate feel about it. handy hatch in front for keys etc. overall very much recommended.(cant bring myself to sell it yet even though i use grp composite most of time hehe)
Basically a big Waveski. Well made, but can dimple in the hull if left resting hull down for periods.
A big disappointment after the versatile Surfjet 305 I had been using.
If you live in Hawaii or anywhere they have fat rollers it will be fine. It doesn't handle steep waves as there is insufficient rocker to lean back and get the nose up and it Pearls too easily. Very slow in flatwater and too big and wide to penetrate the break well. Does turn well with body-shift alone, a bigger fin would be better for control on steep waves.
It's gathering dust in the backyard because it basically only likes one kind of wave.
