i14t q's: do-able solo? any heavier/taller users? seats/ etc

a good used i14t is available locally at a tempting price point.

1)my main question is what about using the i14t with a single person:
-with my weight well over 200lbs & long legs, (assuming an optimized /raised "beach chair"), would an i14t be totally silly looking "bow in the air swamped in the back", or would it still be semi reasonable to handle SOLO for things like: fishing, sailing - or longer trips with a bit of gear up front?
-what about solo pedaling in the front seat, anyone tried that/ is it possible or reasonable? i know i wouldn't have the rudder or would have to jurry rig/retrofit controls , but i'm an experienced kayaker in all conditions so figure i might be able to stay on track in mild conditions

i'm ~230lbs and 6'6 , and i know that if i sit in the back i'll be pooling water on the floor/seat --not a deal breaker for tandem use, & i can sit in the front as well with the kid or wife in back i've been told. and even in the back with the older floppy seats & a wet butt, no biggie, i'm still into it and likely going to pull the trigger on the deal regardless.

of course the pedal drives are the reason for pursuing i14t over other drop stitch tandem kayaks (non pedal) with a more flexible seating position. and as an apartment dweller and kayaking family (and sailboat owner using inflatable kayak/s as dinghies)-- we have always had at least one tandem inflatable of the mid to high range variety over the last 15 years -so i do reasonably know what i'm getting into and their limitations.

2) my other question is if anyone can recommend specific taller "beach chairs" ? (or inflatable seats- what about the sea eagle 'deluxe' ones, perhaps?) ....or point me in the right direction for good options as far as retrofitting/mounting (on a budget, NOT new fancy kayak ones nor hobie brand) ---
specific seat recommendations of course still appreciated regardless of price point, so i might get a better idea of what works.

i know i will realistically need to upgrade from the older style original floppy seats. i'd like to raise the seat 3-4" because i know from a brief 15 minutes on an older outback tandem years ago, that my back won't handle the stock seating position at all---and i will need to be sitting on a 2-3" cushion at minimum to have a chance of being comfortable pedaling

thanks in advance for any advice, experiences, or input.
(even if that advice is that i14t is really not that suitable for 'larger people' & i should perhaps hold out for the itrek 14 double "pedal board style", a thought that is in the back of my mind)

I had a i12s for it's brief time on this earth before hidden seams let go. I think the reason Hobie inflatables have evolved to a "board" style is because the failure rate of the complex seams around scuppers and bow of the "kayak" styles. The boards drain without scuppers and have simple seam routes. That i14t may have way exceeded it's typical life expectancy regardless of good appearance; it's all about seams so buried that are hard to repair. They made small simplifications in later years of the model but the floppy seat ones are old.

Feedback on the inflatables are scarce on this forum and only about 1 post every couple years on the 14. I am bigger than you with a bad back and found the SeaEagle deluxe a gamechanger. I also have their discontinued "fishing" inflatable seat a few inches higher, but it makes things too tippy. You don't need any elevation for comfort, it's all about your recline angle relative to the pedals and the seats resistance to tipping backwards when you thrust against pedals.

Almost any seat not very well secured will flop backwards when pedals are pushed. The SeaEagle deluxe is fantastic since the backrest is like a pyramid with footprint way back to oppose tipping. The footprint also prevents some pooling. Due to low pressure the hull is not rigid and can have localized depressions. I took official advice on this forum that I should increase floor cell pressure by a pound or two and that immediately gave me my fatal leak.

As for solo issues, I speculate you will deal with weathervaning into or away from the wind. Even mine meant for solo did. That and waves may overpower rudder authority at times. I feel you may be overthinking some things and the real issues will turn out to be unexpected ones. If you can deal with the deflation risk and get a low price, you probably can improvise around other issues. i12s was a good sail machine; I'm not sure if the i14 sail location or small sail area will give much performance.
