Good questions! I am always carrying the packraft. I don't really have any options to drop it to retrieve later and anything left laying around just turns into a bear chew toy within about 24 hours. I carry a 55 L backpack which is not large enough to accomodate the raft along with all my camping stuff so the raft gets strapped to the bottom of the pack in its own stuff sack. I sewed my own raft storage bag and an early version was orange but more recently I made a black one that matches the packs better. You can probably see it in the videos now that I have pointed out where to look. The raft weighs about 3 kg and is a fairly dense object once deflated and rolled/folded, so carrying it on the bottom of the pack makes the center of gravity a bit lower and also means the pack does not stick up as high, allowing me to duck under branches and negotiate dense brush more easily. When I checked in for my most recent flight, all my gear together (food for 5 days, 1 liter of water, loaded backpack, raft, paddle, etc) weighed 17 kg.
This summer for the first time I am using a packraft that has a "cargo zipper." This means I can get inside the single tube to cache my gear when paddling. I have to empty the backpack and transfer the gear into 2 light dry bags which are themselves secured inside the raft tubes roughly on either side of my hips when seated, and the empty backpack can fit inside the stern. It's actually pretty quick to do this gear shuffle but still not as fast as simply securing the pack on the bow, so for shorter paddling sections where I will be transitioning soon I put the pack on the bow and for longer paddles (say, more than 1 hour) or if I anticipate rough conditions I will put the gear 'under decks.' So sometimes in the 2 most recent videos you will see my pack on the bow, but sometimes only a small deck bag that I sewed for this purpose.
Coming from a sea kayaking background I at first was dismissive of packrafts as not much more than pool toys. Some of the trips people were doing with them seemed contrived simply to rationalize using the packraft. But with a bit of a shift in attitude I began to realize they offered some unique travel opportunities. We don't have large rivers here in Kodiak, and the outer coasts are best negotiated by sea kayak. But inland waters, bays, and lakes offer a way of avoiding some otherwise horrific terrain and brush, so if you could hit the beach and have a reasonably worthy vessel assembled in about 5 minutes it would actually open up a lot of new terrain. Since the raft is so small and light you can also fly with it easily. Inexpensive "mail" flights between small communities means I can reach most regions in the archipelago for $100-200. Port William, a now defunct herring saltery and salmon cannery on the south side of Shuyak Island, is just such a mail plane stop and it only costs me $140 each way. If I'm feeling really cheap I will fly to a village/cannery and then hike/paddle back home, lol.
As long as the sea state is neither working for or against me, I can cruise at about 7 km/h in my kayak and I average about 50 km per day on trips. In a packraft I can cruise at 5 km/h and paddling 25 km in a day is no problem. But as soon as the wind picks up or it gets a bit rough, the sea kayak outperforms the packraft easily. You need to pick your weather carefully to paddle a packraft.
Other than near the city of Kodiak, there are almost no developed trails in the Kodiak Archipelago. Shuyak Island State Park has a few maintained trails, but frankly the bear trails on the island are wider and better laid out (always trust the locals to know the best routes). I am basically always hiking 'off route' and I follow animal trails whenever possible. Elk make amazing trails, as do bears. Deer trails are okay. But if I don't find a critter path going in my intended direction, I just go cross country.
I have 3 cameras with me. A compact super-zoom point and shoot (Panasonic Lumix DMC-ZS60), a 'pov' action camera (DJI Osmo Action- basically like a GoPro), and the camera in my iPhone. The Panasonic is used for any telephoto shots of animals and also for general scenics. The DJI is for point-of-view shots like while hiking and paddling, and I honestly just hold it by the camera shoe in my teeth, haha. The iPhone is for flowers and some scenics, but mostly I have it along as my gps. They all produce somewhat different color profiles so I have to fiddle a bit when editing so that scenes don't contrast too badly with each other, but in general I have all the focal lengths and angles covered this way, and each camera is quite small and light. I have a mini tripod too (the original Joby GorillaPod).
I'm happy to answer any other Q's. Cheers, folks.
