For the helmsman but what about the poor bugger on the foredeck!

thought u guys would like this. when i get bored i tend to look for stupid answers to stupid questions. Maybe the yacht pic answers my real question. My only REAL stuff was in a 3m rib off of calshot, im still convinced my drop of throttle made it worse. Is a stuff really just getting wet when u hit a following wave?? if so ive done it more times than can count! i kinda presumed a real stuff is when the nose is burried so hard you either submerge (like boatmad vids)or it stops the front of the boat completly regardless of what the backs trying to do, this could result in broach or hooking maybe too??

imho I think the most common is the second type especially in ribs... anyone agree?? due to speeds etc. if so why do so many people presume a rib with larger tubes and an upswept bow to reduce chances of stuffing. Could that not infact increase chances as there is more of a wall to impact into a wave??would a smaller bow such as maybe, banana shark, revenger, phantom not mearly punch through instead of stopping??

My boat is amazing in a following sea and it has a very low profile front... and no tubes!! its also stepped and doest raise its nose to any great extent but it does have a huge flare in bow section that makes it excel, i do get wet sometimes and it aint so good in a head sea or solent chop!!

just thinking aloud and not a rib driver so have no first hand experience of ribs and stuffs

I agree.

Taking the top off a wave and getting a bit wet isn't what I'd call a stuff.

If you find yourself wet, boat swamped and a little dazed, you probably stuffed it (but that'd be a slow one) Anyone who swims away from a stuff like the 19 Phantom in the Cowes vid, is VERY lucky! They're a real neck braker.

And there's plenty of ribs out there now running at, or near the speeds that P19 was running (74mph)

I would agree that a proper stuff includes burrying the bow and coming to an abrupt (and wet) halt...

Stuff: Going from speed to fek all in a blink, shaking off the water from you wet head, whilst wondering what the hell is going on only to find your knee deep in water with the portable fuel tanks floating away between the engines and only being held there by the fuel lines.
The bow compartment of the tubes going flat, because the over pressure valves have let go and it all generally going to shite.
Fortunatly, for me anyway, it all got better very quickly as well
Big toobs and a turned up nose..............didn't make a bit of difference , learning from it......priceless

My definition of a stuff is one I did earlier this year.
Off Calshot going at high speed into shortish steep waves, flew over a few of them then came to an abrupt halt when the front half of the boat disappeared under a mountain of water. The boat came to an sudden halt and everything went eerily quiet. As this was the first time it had ever happened to me I just sat there for a few seconds looking at my poor boat totally full of water. Even the transom was under water. Don't underestimate what goes through your mind, I've got a a fair few inches of water in boat on loads of occasions but nothing nowhere near as dramatic and instant as that. My greatest relief was that the tubes were intact and after trying a few things I realised the engine was still working so I managed to get the boat on the move and tilted up at a sharp angle by tilting the engine out I got rid of a lot of water. the bilge took a good 15 minutes to get rid of the rest of it. No lasting damage, thank god. I have stuffed it again since off the Needles and now know to keep going as this is really the only way to get rid of the tremendous amount of water.
The whole experinece was on a par with having a big car accident. Its just as dramatic and the brain reacts to it the same.
Its one of those things you need to do to be ready for it in an emergency and its one of the things I would have liked to have shown to me practically on a RYA course.
My next exciting experience is trying to work out how steep a wave my boat can safely handle without tipping over. Obviously I don't want to tip over but I want to know how far I can go.
What I would like to do is get a camera set up on the A Frame like has been done recentlt on this forum and then be able to study the results.

Which is why I decided to stuff my Rib on my level 2 course! The instructor showed his skill however by ducking toward the stern and with his oilies on managed to stay fairly dry, I however ducked forward toward the wave thus presenting my high necked jacket which acted as a funnel, filling not just my jacket but all the way down to my boots!
Similarly to Biggles I thought I'd lost the engine for a few seconds and was in a right old haze as to what to do next, live and learn

I heard that there was a guy on the foredeck who got plunged 11 feet under the water.

Most true offshore RIBs have turned up noses and big tubes - look at Ocean Dynamics - Delta - Tornado - Humber/Quinquari - Avon etc etc.

They do make a stuff a lot less likely - although when the stuff DOES occur they prob do make things worse!!!

This video shows it clearly - look which boat stuffs - it is NOT the one with the upswept nose.

Bit like driving a 4x4 down a steep slope - if you have a big overhang at the front you will bit the ground hard - approach angle they call it.
