@@stringermedia5875 The waves are about the same length as the boats, so if they add power on the downstream, the boats and occupants take a severe beating. Better to stay off the gas and roll through the waves.
You prolly dont give a shit but does someone know a tool to get back into an instagram account?? I somehow lost the password. I love any assistance you can give me
@Ephraim Dominic I really appreciate your reply. I found the site on google and Im trying it out now. Looks like it's gonna take a while so I will reply here later with my results.
David Attenborough’s narration: Every year the jet boats begin the difficult journey up the river against impossible currents. Some are not so lucky, but for the ones that do succeed, they will be able to spawn a new generation of jet boats and the cycle will continue. Me: isn’t nature amazing!
The poor blue boater just couldn’t get the hang of it till the end but put up one hell of a fight and won. Cool to see a definite pattern in the wave 🌊 and all way changing every sec so you have to see your own pattern that no one ☝️ else but you can see. That’s a dam good gift to have. Way to go for all who took part in that awesome talent of skilled professional pilots of these boats.👍🏼✅🤩😎
Great shots of the boat taking on this rapids. Handling waves in first run was not best. There is no better thrill than taking a jet upstream on these white waters
Welawan Arus yg sangat Deras sungguh Perjuangan yg sangat2 Luar biasa. Harus di Imbangi dgn Tenaga Mesin Jet sky yg Handal. Semoga ada jln dan Solusi yg lbih muda👍💪
That whitewater is so aerated that the jet is having a hard time "pumping" water for thrust. In whitewater like that a jet boat can loose 60% of it's thrust or power leaving a 300hp boat with just over 100hp effectively. I was helping build an off-grid cabin up river on the rogue river. We had heavy rain for a week and were expecting the river to be up and fast but wow. Just about every trip we made was with a ton of wood and a ton of building supplies. we got into a couple of aerated spots of water and lost most of our thrust and buoyancy, was quite scary.
Great video Maybe next year tow a tuber behind your boat that would be even more entertaining 🇨🇦 Greetings from Vancouver Island British Columbia Canada 🇨🇦
@@Kitchfox there's a shit load of Salmon rivers in New Zealand. Have a search through youtube, you'll find heaps i reckon. One of the best (biased), is close to my old home town, Oamaru; it's the Waitaki River. I've seen some monster salmon jumping out where the fresh meets the salt, getting ready for their run... 30kg plus, and much bigger back when I was in my teens. Maybe it's not as good these days, as with most fishing, who knows.
Years ago I had a 22' North River jet. Chevy 454, Hamilton 212 pump, extra wide, 1/4" bottom.......the wife said it was her or the boat. Well, glad to say I chose her. Couldn't tell you though what my ex is up to these days.
I saw boats do this up close while on a rafting trip on the Snake River thru Hells Canyon. there are serious hydraulics on these reeves. The guides told us that there are many a boat that gets sucked under by the hydraulics
I seem to recall that fish-like propulsion has been tried on boats, but it always fails. Fortunately or unfortunately, I've not dived into the topic to figure out why.
Just watched again. There is definitely a dent with a hole in the middle leaking water. How much water weight is in the boat even before the first attempt?
It has a recessed bow that drains out the bottom (by design). Maybe 200-300 pounds each time the nose stuffs into a wave. But it drains and splashes out pretty quick. You can see the recess pretty clearly on the down-run at about 6:17.
These come with different v8 or V6 motor choices like a vortec or a 350, these come with Hamilton, Berkeley or American turbine pumps, a manufacturer in Idaho is custom weld there is also precision weld among others. These are incredibly durable and cool boats and are great.
