Bobs Lake boat crash.

water equiv to a spike strip on tires.
It would catch everything, including canoes AND swimmers.
And it would get messy real quick... ever see a boat "nose in" at speed? The soft squishy humans get tossed out the front, to be pelted with shattered boat... and fuel tanks and coolers. Fun to watch... if you don't know anyone involved. I watched my cousin nose in, in an unlimited outboard hydro, at a bit north of 100mph... the biggest part of the wreckage was the transom, the rest of the boat was just GONE. Cousin didn't fare so well... he got hit by the motor, spinning at maximum revs

A floating polypropylene rope will stall an engine. If it’s running at 20mph, it will unwind in a second, a canoe will pass over it, a swimmer under. But a speeding prop will get tightly wound and stall - zero chance of nose in, the boat behaves as if the captain cut the throttle or it und out of gas.

Chopping the throttle at over 60mph doesn't behave well. Especially when the prop is physically stopped and adding drag. I think it would be hard but not impossible to get the nose to dive (especially if most of the boat was out of the water).

Been margining a lot of years… only once have I put the nose under, and that was in a sudden force 7 gale in a 16’ Donzi on Simcoe.

In fair conditions it’s almost impossible for a pleasurecraft. About the only way your gonna throw anyone forward is grounding into the shore or colliding with a bigger boat.

It's easy to do intentionally on a jet boat.

Jet ski/seafood yes, jet boat - never see or heard of anyone going under in small pleasure craft. The only time you’re putting the nose under is if you’re a novice operating in choppy seas that are beyond your marining skills.

Race boats are a different story as motors can exceed hull speed.

I'm going to preface this by saying it is a stupid idea and should not be tried. Also, it works.

In a seadoo sportster (and maybe others), while planing, throw it in reverse with lots of throttle and it will dive. Water will mostly fill the boat but it has large cockpit drains and it pops up within a couple minutes. Engine is in a separate compartment so it doesn't get flooded by your stupidity.

EDIT:
Here's are video's of people doing it in different jet boats. As expected, where lifejackets are present, the asshats are using them as seat cushions at best.



This one is super annoying but they completely buried it with gunnels at the water line when done.


As for pressing the ejector button, that doesn't necessarily mean you dug the nose. If you were already right on the edge and chine walking, I highly suspect a stopped prop would result in the equivalent of a highside where the boat rotates and digs in and it would be violent and brutal. Normal boats at normal speeds wouldn't need to worry about that outcome.

Ok, asshat proves you can do it on a jet ski type boat. I was thinking a conventional v8 powered jet (Berkeley).

But back to the rope in prop. Not going to put a boat under.
 
nose in on any conventional power boat would be pretty hard , but try hard enough and anything is possible . Oakville powerboat did it last year in 4ft waves , 18ft boat and two guys sitting in bow seats , swamped with a wave and then the boat turned sideways and turtled. Put 4 guys in the drink at 6 kph.
I think my fear of a powerboat at speed hitting a floating poly rope is it would not wind into the prop, just catch the motor skeg and stretch about 20% and rip the motor off it it didnt snap. Just rolling off the throttle at 30mph will throw passengers forward , adding any leverage could make it ugly
 
While the knee jerk reaction is tempting, any booby trap is at least the thin edge of the wedge of something besides the boat going under.

I've done some cottage service calls and during the week, the lakes were serene. On the weekends it was life in a blender.
 
Your average boat buyer wants a boat that is "safe" as possible.
Your average PERFORMANCE boat buyer, Mr. Picklefork, is willing to trade some of that "safety" for performance, as a lot of the "safety" will slow the boat down.
... a lot like cars, trucks and motorcycles (MotoGP doesn't use ABS).
... so your average boat will be difficult, but not impossible, to nose in. Performance boats will. You can nose in a hydroplane by reducing the throttle too quickly at speed.

I'm not talking about creating a catch line like you see on an aircraft carrier -- just a floating rope attached to nothing.

Wouldn't that just float away with the current?

Would it help reset this argument if I said I don't think any of you would actually set a booby trap like this, and that we are all better off for that
 
I would not set a booby trap like this .
Would I snorkel over to that boat at 2am and pull the prop off the motor? Really quite possible .

There's a group of guys that run fast boats near our place...
They make passes above 100mph.. a couple of them are probably nearing 150mph
People complain about it.. but everyone gives them room to do it.
Do something too dumb.. and someone will tell you off.. or worse.

I f'ed up a few years ago.. did something I shouldn't have... and the next morning found my seadoo upside down on the bottom.

If you take it off, it would either be easy to find or obviously removed. If you loosen the nut, they may get a ways from the dock before it falls off.

I don't mind fast boats. Similar to bikes, time and place. Sadly most of the fast boat owners I have seen suck at time and place. Decades ago, I almost got taken out on the Otonabee river by a moron pushing things to the limit. A go fast boat probably close to 30' running as hard as he could bank to bank and apexing blind corners. Similar to moron bikes on TotD, survival based entirely on luck and hoping the guy you crash into has a smaller vehicle than you.

As with most things, fines need to be relative to pot size to have an effect. For driving like that, even with no crash, I am 100% ok with seizing the boat after conviction and selling it at auction. No warning required, the behaviour was so dangerous you've lost your boat the first time you got caught. Get to the trial quickly. There is no reason for a year plus delay.
