Due to storage limitations, I am thinking about purchasing a i11s and have a few questions that hopefully you guys/gals can help me with.

1. Is it ok to store it folded up in the garage in Florida or would I be better off trying to find a place inside? If inside, can anybody give me a comparison/dimensions to how big the bag is (suitcase size maybe)?
2. I have a 4 year old son. Any way for him to sit behind me? I have an inflatable paddleboard now that he sits on the front while I paddle. Thinking of getting rid of that and purchasing the Hobie so we can cover some more distance with the mirage drive. I am 6' and weigh about 185. He currently weighs about 40.
3. How hard is it to actually pump up by hand? I feel like I ran a marathon when I do the paddleboard by hand, but it is much higher PSI.

I’m sure there will be other questions as I look more into this. Thanks in advance for any guidance.

The Hobie i11s web page sez Bag Dimensions: 36" x 25" x 12". You might want to take a picture of how it is packed on arrival... some folks have trouble stuffing it back in the bag when it is stiff and new. There is a particular documented way to do it, and now my larger i12s fits in essentially the same bag easily.

I also kill myself pumping SUP's up to 15+psi. I find it very quick and easy to fill my i12s to 4psi. I'm puzzled about why some i11s owners decide to use an electric pump... I couldn't even hook up the wires and hose in the short time it takes to manually pump. The pump cannot be braced against the ground, so you are kind of squeezing arms together. Worthwhile to switch arms for the different compartments.

For a passenger I have thought the best way on my i12s might be back to back, because there is little room ahead of the footpedals, and yet you probably don't want weight maxed to the stern. But an i11s owner should be better able to say what is feasible.

P.S. for a small passenger, you might use a seat like below. I use this one and a larger one from the same company. It could be in addition to the Hobie seat or instead. The rear face is sloped (that is it's genius in giving solid back support) so it can support 2 people in comfort back to back. Probably should tie it down because it is slightly rolley polley on a flat surface.

inflating an i11s with the Hobie supplied manual pump is quick and easy. It is really fast if you are transporting it just folded in half in the back of a van or SUV because the center chamber is still about half full of air...

I inflate the main chamber with a Coleman cordless electric pump, while I fill the two side chambers by hand. In the time it takes me to inflate the two sides, the main is inflated. I do a couple of hand pumps to the main to top it off. Takes half the time to inflate the whole thing than if I do all by hand. The Coleman will inflate the main 3 times on each charge, no wires to hook up at the water just recharge at home between each trip.

To deflate I open the valves and then use the electric pump to suck the main chamber flat for packing in the bag. Makes it nice and flat to stow in the bag. I store the bag in a cool back room so can't comment on storing it in hot outdoor conditions. I wouldn't leave it in the sunlight but in a shaded carport might be OK.

I don't see why you are puzzled. The Sevylor plugs into car cigarette socket, takes about 7 minutes to fill all 3 chambers. During that time, I am mounting my rod holders to the cooler, tying up my rigs, checking VHF, etc. When it's 95 degrees out, I'm not sweating before I even hit the water, and not wasting time pumping when I can be setting up my boat for fishing. I can see if you're not fishing, it might be superfluous...but I would argue hands free pumping is superior under any circumstances.

That electric sevylor looks revolutionary and I later praised it as such in the gauge and pump topic. Also someone earlier mentioned a hybrid turbine/piston/battery pump with similar capability but quite high price.

Most of my launches don't involve a vehicle, or at least yak suitcase is rolled too far from any secure vehicle or building where pump/battery could be returned to (without the unattended yak being subject to theft). Manual pump, suitcase, and all must be drybagged and secured onboard... certainly don't want to add battery.

Hand pumping my larger i12s seems only about 10% of the time and effort of setup... it almost seems like a rest because I don't have to bend down so much compared to securing all my gear or manhandling the boat to water. It seems just pfft-pfft a couple minutes and it's done. Well there was also tedious fiddling with my old pressure valve; my new one has positive lock tongs, but I guess the sevylor has built in pressure control. I do usually set up in broken shade mid 80's with wind because sailing is the usual goal.

I also have 2 giant inflatables that require car launch and cry out for electropumps. One takes me several hours to hand pump including rests and almost kills me in the sun. For this I bought but haven't tried the sevylor. With the other one I tried the typical turbine pump which was probably more trouble than the excellent handpump that came with it. I will expound on the negative circumstances, but even with the sevylor I don't expect I would bother to use it for car launch of my Hobie.

I noticed on Amazon comments that the non-sevylor turbo pumps tend to self destruct if ingesting dirt. I found it diabolical to position the pump so the intake wasn't trying to dance to the ground. The stiffness of the hose attached to the ever changing orientation of the bladder valve meant I had to either hold it uncomfortably or be ready to dive at it every few seconds.

Also the non-sevylor pumps as a rule only fill about 2/3 pressure, then you have to get the handpump to finish it. Endless fussing with hoses, pumps-plural, wires, and pressure gauge. Also they overheat easily... even the Sevylor says after 10 min you have to rest it for 30 min!

Now some issues probably limited to me... I can't imagine compromising vehicle battery power for a pump. I generally need a jump start all the time anyway, and wheel a handcart with 4 batteries just as others would bring keys to a car. So I do have a small bit of spare battery juice on the side. I found my vehicle cig receptacle very fragile and easily broken with overuse... well I will stop there.

I GoPro'ed myself pumping up my i11s with the Hobie manual pump and installing the seat, drive, BlackPac box, and paddle, here is the time-lapse youtube of it:

at the end, you see me check my phone and hold up my hand indicating 5 minutes. I didn't really try to do it fast.

The Sevylor is a no brainer for me, but hey: different strokes. Just wanted to solve your puzzle re my own experience.

I've watched that video Roger, and I envy your upper body strength. It's impossible for me to get the center chamber over 5psi without using my body weight to push into the pump, let alone having it suspended off the ground. I also deflate completely when folding.

Maybe that's your problem; shouldn't your target be 4psi? It used to be explicit in the manual the following:

Firm, Remove wrinkles... 3-5 lbs.

I think they have removed that in new manual for that vague wrinkle stuff. I had a SUP rated for 3psi in the outside and a 15psi center spine, but I don't think the Hobie bladders or pump is designed for that.

I find the Hobie pump to be self limiting with regard to pressure, once it gets high enough, some air leaks during a pump where the tip is in the kayak valve and at that point the chambers, center and side, are plenty full IMO. I hold the pump down firmly but certainly don't put my weight on it to try and force more air in...roger

I use a gauge, and find that once in a while with the Hobie pump I have vastly overpressured one of the bladders and have to bleed. Not only stressing that bladder but maybe distorting how the bladders mate with eachother (probably more important with i12s).

Another of my inflatables has "overpressure" valves, and on some of those you are told to pump until it burps. Another had a foot pump designed to resist overpressure. A faulty gauge told me to force it and that pump broke. Now I have a gauge for every inflatable, and mostly crosschecked against eachother. For the wild variations that a builtin pump gauge gives, I go by the reading appearing for a slow midstroke.

Have you ever gauged after pumping up? Just curious as to what kind of reading you get when you stop pumping. With my gauge, at the point where I don't have to lean into the pump it's barely getting over 3 psi. Of course, my gauge could be giving me a false reading.

nope, I don't have a gauge that fits these valves. I judge it is full enough based on feel and also that I can walk around on the deck out on the water. cheers, roger
