According to the internet Hobie had reverse in all their kayaks starting in model year 2017.
They came out with the Passport, their lowest priced kayak, in 2019, and it doesn't have reverse. I have two of them, both upgraded to the same reverse drive in their other models.
Passport rudders are completely different than those on other Hobies...they use a solid fiberglass rod from the rudder control lever back to the rudder, a simple and very stout arrangement, instead of the typical Hobie rudder cables. The Passport rudder system will not 'torque-over' in reverse; it stays where you leave it.
Hobie's biggest pedal drive kayak competitor is Old Town, which utilize a prop drive with instant reverse. It's a good system but wouldn't work well for many of the small trout lakes I fish because of structure like weeds and logs. Hobie drives have kickup fins that simply fold up out of the way when you hit something and resume their correct position as you continue to pedal. The rudder is also spring loaded and moves up from obstructions.
Weeds are not a problem because (as
@Northern describes) you just 'flutter-kick' through them...and in the off chance you did get tangled up you just easily lift the drive out of its drivewell scupper to clean it.
I don't stand up in my kayaks, nor did I do so in canoes or prams. While I'm not a particularly good flycaster I've casted sitting down for over 65 years when afloat. I think standing up tends to more easily spook trout and is unnecessary when seated in an inherently stealthy watercraft like a kayak, canoe or inflatable. Trout ain't bonefish.
If Hobie is smart it will start selling Passports with reverse drive (apparently some Hobie dealers already will do so) at a price competitive with Old Town, instead of focusing on extremely expensive ($6000), heavy (150 lbs), and exotic models like their ProAngler 14 with 360 Mirage Drives.
