How to choose an inflatable kayak

For most buyers the answer is the Sea Eagle SE370, and the reason is that it is the only boat in this registry that does not force a choice. If you walk to the water, buy the Sevylor QuikPak K1 instead. If you drive to it and want the toughest skin, buy the Intex Excursion Pro K2. If the bag has to be small enough to carry on your back, there is exactly one answer and it is the Advanced Elements PackLite.

Those four answers come out of four questions asked in a fixed order. The order matters more than any individual specification, because each question eliminates boats that the next question would otherwise have let through.

Question 1: where will it live, and how does it get to the water?

This is first because it is the question that decides whether the boat gets used, and because it is the one people answer last. A 48 lb bag that has to come down two flights of stairs is a boat that goes out twice a summer.

Two published specs answer it: hull weight, which everybody publishes, and packed size, which five of our eight manufacturers publish. Linear inches -- length plus width plus height -- is what an airline measures, and 62 is the economy checked limit at United, Delta and American alike. The full pack-size method is set out here.

Note what this question does to the two Intex boats. Both have strong figures elsewhere and neither publishes a packed size at all, so a buyer whose binding constraint is a cupboard or a car boot cannot evaluate them on the one spec that matters to them. That is not the same as the boats being large. It is worse, because it is unknowable in advance.

Question 2: what does it have to carry?

Add your own weight to your gear, and compare that against about two thirds of the boat's rating rather than the rating itself. A rating is the point at which the manufacturer stops making claims; a boat loaded to it sits low, pushes more water and handles badly. Why we use two thirds is worked through here.

The practical floor for a single adult with gear is a 300 lb rating, which removes the PackLite at 250 lb. If anyone is coming with you, the answer changes sharply, because a tandem rating has to be divided between two seats before it means anything -- the per-seat arithmetic is on its own page, and it disqualifies three of the four tandems we cover for two adults.

Question 3: what water, and how far from shore?

Hull length divided by beam is the closest thing to a handling spec that falls out of numbers every manufacturer publishes. A longer, narrower hull holds a line and carries speed; a shorter, wider one turns easily and resists tipping. It knows nothing about rocker or tube cross-section, which is why the page that uses it does not rank on it alone.

Two answers fall out quickly. For sheltered water close to shore, width is worth more than length and the short wide boats are fine. For open water, a long hull and a high chamber count both start to matter, because the cost of a problem rises with the distance back.

One answer we will not give: none of these is a whitewater boat, none of these manufacturers claims otherwise, and we have written separately about why we will not pretend one of them is.

Question 4: what will the maker actually tell you?

The last question is the one nobody asks, and it is the most useful filter in the category. Four specifications decide a purchase -- working pressure, chamber count, packed size and warranty term -- and across this registry most makers publish some and none publishes all four.

Not one manufacturer in this registry publishes a warranty term for its kayaks, which is worth sitting with. On the paddle board side two makers do. The brand page ranks the whole registry on this axis.

What this page deliberately does not rank on

Material names. Every maker has a trade name for its skin and almost none publishes a thickness. Sea Eagle's 38 mil Polykrylar on the SE370 is the clearest figure anyone here states, so comparing "three-ply PVC" against "Duratex" is comparing marketing copy. What the material names actually mean is here.

Inflation time. Only one manufacturer in the kayak registry makes a time claim at all. We compute times where a volume is published, and no kayak maker publishes a chamber volume, so the kayak column of that table is blank. It is a real gap and not one we will fill with a guess.

Anything we would have had to paddle. We have not been in any of these boats. Every figure on this page is a manufacturer's published specification or arithmetic performed on one, which is a narrower claim than most guides make and a checkable one.

Working the four questions through

Answer one: you walk, cycle or fly to the water. The carry question takes you straight to the Sevylor QuikPak K1 at 18 lb, or to the PackLite at 7 lb for the complete system if the constraint is genuinely severe.

Answer two: you drive, and you want the boat to last. The carry question stops eliminating anything, capacity and skin take over, and the Intex Excursion Pro K2 wins on the toughest published fabric in the registry.

Answer three: you are not sure yet, or more than one person is coming. The Sea Eagle SE370 is the boat that keeps the most options open -- the highest capacity here, a packed size inside the airline limit, and a maker that publishes more than most.

Answer four: it is open water and you are going a distance from shore. The Advanced Elements AdvancedFrame's ribs and seven chambers are the structural answer, and you accept 36 lb to get them.
