Where can I find small version of kayak for adult?

I'm going to be traveling around a lot so I want to buy a kayak, except I don't want it to be that BIG but not too small for a full grown male adult. And definitely light enough to put on top of my honda accord ex coupe. Does any one know where I can buy such things like that? I don't know how to describe it… Really small kayak but not for kid, for adult.It'll be bonus if it has a sail attachment too!

Kayaks are designed ideally to accommodate specific loads. Buoyancy is the problem. If the kayak is overloaded it will sink beneath its design waterline. Visit a dealer.

A kayak has to be a certain volume to support the weight of the paddler -- the hull has to displace a weight of water to properly counterbalance the paddler or the boat will sink or ride too high and be unstable (with too much volume). If a kayak is short it has to be wide to add the volume, so it typically will not be any lighter than a longer and narrower kayak. Also, short wide kayaks are sluggish to paddle, track poorly and are unstable in rough water. Some short kayaks are made strictly for whitewater rapids, for quick turns and surfing -- again, these are not suitable for flatwater speed or straight tracking.

The average sized woman is best fitted in a kayak between 12' and 15', the average sized man in one from 14' to 17'. If you are heavier or taller than average, you would need to be at the upper size end. An adult will not fit in a kayak sized for a child. You "wear" a kayak, not just sit in it, and the adult but is too big and the legs too long to fit in one scaled for a child.

You also can't use a sail attachment on a short kayak -- it has to be a touring style kayak with a vee shaped hull, preferably in the upper range of length and with a built in skeg or rudder for tracking control.

Any size kayak can be carried on a Honda Accord. My ex boyfriend had one and we hauled 85 pound 16' long canoes and 65' lb 17' long kayaks on it quite often. You just need a good roof rack, like a Thule, and to tie bow and stern lines to the bumper in addition to using strong straps to mount the kayak to the rack. It is actually easier to load long thin kayaks than short wide ones. I'm an average sized woman in my 60's and I load 17' kayaks on my little Subaru all the time.

If weight is your primary concern along with portability, look at inflatable kayaks like the Innova Sunny or the various models made by Advanced Elements. (don't bother with Sea Eagle or other "pool toy" like inflatables). An even better option is folding kayaks. Do a google search and look at the Orukayak (a fold up kayak that weighs under 30 lbs), the Pakboat Quest 155 (a hybrid inflatable and folding kayak around 30 lbs) or the Feathercraft Kurrent (another 25 lb folder). Folbot and Klepper are two other folding kayak companies which make sailing attachments for their boats. There are various aftermarket sails for kayaks but they are not cheap.

Some of these are quite expensive -- if you are on a budget and have a few tools and space to work, you can build your own lightweight skin on frame kayak (which is what all original kayaks were when the Inuit used them) from free instructions on this site:

But since you are focused on portability and sailing, why not consider a sail board/wind surfer?
