Great discussion Zach. An issue with whitewater especially, is the aeration. A swimmer might be in water that is 50% or more, just air, which negates much of the flotation. Another good reason for higher flotation.

I really appreciate this episode, Zach. I'm a beginner rafter mostly doing class II-III+ and have an interest in moving up, but as a fellow 220lber I really hadn't considered how my vest was basically doing the bare minimum for me. I watch countless KZfaq videos on rapids before I run them and I've seen several where the swimmer is underwater for a scary amount of time. I can't help but wonder how much safer those swimmers would have been if they had a vest on that sucked them back to the surface more aggressively. You've inspired me to go in for a NRS Big Water Guide (If the regular had a knife slot I'd get that, but it is what it is) PFD with 23lbs of flotation (over my current one with 15.5) before my upcoming class IV trip next month. Edit: ordered. My old jacket is much more breathable so I'll hang on to it for packrafting and everything up to class III, but I do feel a lot better about this. I shopped at REI before getting my last jacket and I don't think a single jacket they had in store was more than 16lbs so I didn't even know these existed.

Good video and I agree with you 100%. I have always used a NRS Big Water Guide, and find it quite comfortable, even when kayaking. I personally like a higher ride in the water when swimming due to the things that you mentioned, often to the dismay of the very few "macho" boaters I paddle with on occasion.

@anthonycarpenter5411 Жыл бұрын

I agree 100%. Fit with shoulder straps is important too for me. My 2011 Astral LE pfd fixed shoulder straps have it fit too high on me. It still looks new with some fading. For many years I have used a Kokatat ronin pro that enables straps to loosen where I can have it lower on my body. And all the pros you mentioned hold true for me. Same flotation at 16.5 lbs, but very different performance. 5’8” 170lbs, 17 years rafting experience for reference

Fit is so important. Had a bad swim in a high flotation vest. It was tight, but rode up so that my mouth was below water level much of the time. I ended up using one hand to hold my life jacket lower, which inhibited self rescue. Have swam since in rescue classes in a vest with lower flotation but a much more secure strap and buckle system and did much better.

Think this is probably the best video I've seen from you. Note that the body is below boyancy neutral, that's why you sink to the bottom when you have no air in your lung, but with air and the air in your clothing you are near neutral. Where it comes to be 'stuck in a hole' because of high flotation I'm pretty sure that comes from Weir incidents, never seen that on the river.

Not a rafter, but I enjoy your channel as lots of your gear reviews and risk management mindsets cross over with canoe tripping. I'd love to see a pfd design where you can add a piece of foam to boost up the floatation based on the needs for the specific trip. Flat water trip, low profile, sleek, lots of mobility for paddling. Whitewater trip, add a foam insert into a sleeve to gain some lbs of floatation. I could see this being beneficial across the paddling industry for those that are into multiple disciplines of their activities.

I wore an Astral Green vest on the GC last summer and, after some of Gear Garages earlier conversations about this, cut a pool noodle and would stuff it in my hand pocket for the bigger water. I realize that it goes against the manufacturer's design and could create other hazards but, three pounds of added float is three pounds. Fortunately, I kept the boat upright and never swam on that trip so I didn't get a real life scenario test. I did use it a bit in a swift water rescue class prior to the trip and it didn't hamper my ability to swim.

I’ve been shoving thin foam sheets into pfd pockets if there’s room for them. The Astral Green jacket has somewhat of a sleeve/pouch potential on the inside of back panel. I have yet to cut a price of foam to insert here but I think a thin foam “sheet” inserted here could add a few more pounds of floatation.

I ended up swimming Tumbleweed in Alberton Gorge mid May of 1997. I think the river was around 30,000 CFS. I was wearing a full 7mm wetsuit and a low float PFD. Despite being a young, strong swimmer, the river sucked me down and kept me down for over a minute. I agree that we should all probably be wearing higher floatation PFDs.

I have been looking a lot of pfds online, and you are right, there are not many options for more float. Some of us definitely need more than the minimum. I sink like a stone and I only weigh 185. I hope more manufacturers will figure out there is a demand for more float. As far as what is on the market now, the newer version of the NRS Zen Rescue has 18.6 llbs, which isn't as much as I would like, but it seems better than the most other vests. Many sites online are still listing the older specs for the Zen, which has 17.5. I emailed NRS customer service and they told me the new ones all have 18.6. Of course, I don't know if the extra weight of the rescue harness offsets the extra float or not. Hope this helps.

Well said Zach. As an ageing middle aged man who has been naturally floating a little more these days ;) , agree with everything your saying especially in bigger water and spring flows. In big hydraulics with more mass these days I definitely flush deeper than years past which can be alarming for sure. Also, NRS used to have a shirt that had built in extra floatation years ago but haven't seen anything like it for many years now. That could be a nice addition to a typical (low float) 16-17lbs PFD when needed. Any thoughts on something like this?

@berndbegemann6798 2 жыл бұрын

thanks for the video! can you recommend a light whitewater pfd (for packrafting) with a lot of buoyancy? I weigh 110 kg and 70N is not enough buoyancy for me. but I only find ww-pfds up to 75N.

I got a NRS big water guide PFD this season for doing more challenging rafting trips, the only downside is the pockets kind of suck, idk where i will put a knife. Ill get a NRS Zen when my blue jacket wears out in a year or so. the ZEN seems to be a good sweet spot at 19.6 lbs of float. Just because I like to argue I would contend that a bigger pfd will increase your drag in the water. Drag is based on surface area and the way a pfd works is by being low density by virtue of large volume and low mass. Large volume = more surface area = more drag. Even if you are bringing some volume of your body out of the water, the volume of PFD required to do that will be greater than what is displaced. That being said the benefit from a bigger PDF of coming to the surface quicker to start swimming sooner is a larger factor, plus giving better vision and preventing dunks to need to re-orient yourself. Have you ever seen the whistle get caught on a perimeter line? I moved my whistle from the shoulder spot to the pocket zipper as that's where I keep my knife on my green jacket. Petition signed ty Zach

@GearGarageTV 2 жыл бұрын

This "Large volume = more surface area = more drag" is absolutely incorrect. A PFD can have more volume and maintain pretty close to the same surface area. A rocket has a small surface area and a large volume. A parachute has a large surface area and low volume. The surface area that matters for drag is what is facing the fluid. A PDF doesn't generally take up space outside of the body so it's effect on surface area for drag is negligible.

@erincd12 2 жыл бұрын

@@GearGarageTV Certainly the relationship between surface area and volume is influenced by shape (rocket vs parachute) but it is still proportional, you cant increase one without increasing the other without changing the shape of the object. for PFDs and bodies I think we can say they have a similar ellipsoid segments. I would agree the drag created by a pfd would be negligible compared to your overall body...its just less negligible than the negligible gain of displaced out of the water. Definitely getting into the weeds, but the surface area beyond what is "facing" the drag would also have an effect i.e. if you are freestyle swimming your thighs still create drag with dynamic friction and all that. Plus pfds like the green jacket have the external pocket with created more surface area for drag than if it was a solid piece.

The big problem I have with my high float vest (NRS Guide vest, 22#) is that it makes it harder to row. I'm sure I'm not the only one. I took both my vests on the Grand Canyon last month, since we needed an extra vest per NPS requirements. Mostly I wore the low float, but but the high float on for some of the more difficult rapids. I rowed the whole thing, and never swam, so who knows?

Havent seen full video yet, but last year i had a very nasty swim in a Rio Claro, Chile in a hidraulic of a waterfall wall, i ended up being suck all the way to the buttom and released. If the water didnt suck me i would probably have died because i was stationary against the wall. I have always wondered what would have happen if i had a high flotation pfd, it is possible that with more flotation the water didnt suck me down. I was using a very old tipycal astral rescue pfd that im sure it have lost flotation.

A lot of rafting companies use high float pfds for their guests. Many of these guests probably aren't going to aggressively self rescue. They may get pulled into the raft by a companion or guide. This supports your contention. I think one thing to consider is when boaters are wearing old PFDs (sun damaged and lots of mildew) that may not have the full level of flotation. They also may not realize this pitfall. It may look cool and telegraph your level of experience, but may not be a good risk management approach.
