calias in the drink

[Jeremy87]

Boat floats trailer sinks, boat would lift the the back wheels even higher once it separates from the trailer.

FNQ, maybe its the weight of the water that gets inside the car. Once the car has water in it, thered be no stopping gravity.

Reminds me to get those bald back tyres replaced.

Anybody know which GC ramp it was?

its the Turana St Ramp, I use it all the time... theres nothing wrong with it....

Not related to the Holden but how come when a boat on a trailer is draging in a vehicle backwards it doesn't just stop once the boat floats or the boat and trailer float? Anyone seen this? Surely the car would stop it's self once the weight was removed?

All just slime and no front wheel handbrake?

cheers fnq

I'd say probably Aberts theory at work here e = mc2 (energy = mass * velocity squared)
Once the car started sliding it obviously had enough energy to keep moving

It's for this very reason wherever possible I have always used 4wds to tow my boats

Geeze G, looks like you've still got a lot of work to do looking at all that paperwork under the paper # better get to it # and get off here...... #

[Gbanger]

i could work all day and not even scratch the surface

to FNQ - thats we thought when it happened to us (this was years ago now anyway). Unhook boat and she'll be right - WRONG

The car started to move so we quickly released the boat (one person in the boat driving on) but the mass of the car was just not stoppable once it had started to slide. it just all goes down in slow motion.

Our case went to court and the Council was proven to be negligent, ramp was overly steep and instead of having draingae channels cut horizontally across the ramp they slope down towards the water, so the car got on the grooves and skewed down.

Council then instituted a steam cleaning regime and warning signs on the ramp advising people to use wheel chocks.

When its never happened to you - you see it and just think stupid fools dont know what they are doing. I guess its a bit like people you see trying to throw boats off the trailer by reversing and then braking sharply. Ive seen many many boats bounce off concrete.

Yes Bigmack,
Seen a few do this , pretty stupid me thinks. # [smiley=dunce.gif]
I managed to launch mine onto the concrete, albeit very slowly (no I was not trying the aforementioned stunt).
But I did undo the safety chain before backing down (never again) , the winch had slipped its gear and the boat slid off the trailer with the winch rope still attached and the handle spinning around about 1000 miles an hour. # #
Scarey stuff watching your pride and joy disappearing from view in the rear vision mirror and you are still 5 metres from the water. # # #

Anyway thankfully I had the motor trimmed right up and she landed on the rear edge of the keel for no noticable damage.

TonyM ,
I have a 4wd now also , but I dont get out and lock my hubs in unless on sand or it looks slippery. Before that had front wheel drive, which kept your driving wheels at least a car length out of the water. #

had a commodore float in the back yard once (not mine) during floods. It was fairly easy to push around until the wheels hit the ground again and the handbrake worked again. I guess the water might have been 900mm deep? Not very deep. Front wheels stay on the ground, but the back end floats readily enough, so the tide would grab it quick enough. Still a jet ski owner so no mercy - Isn't there a bounty on their ears like foxes?

[Wear_the_fox_hat]

HUH!!!!!!!!!!
What's that about hunting foxes???

Tony, you're along the right lines in terms of momentum, however e=mc^2 applies to the energy of atoms (from memory), not momentum . The main thing is as soon as it has started sliding, there is no way the car will stop, even the external force pulling it down is less. The weight of the car hasn't changed, and still acts to pull the car down the ramp in the same manor.

It might have floated because of all the dirt and mud and crud in the water. Makes the water more dense and stuff floats easier. This may have been why urs floated. but then again... you may have had some air bubbles trapped somewhere which also helped it float... guess it's just one of those mysteries.

once it's in the drink most sedan will float at the rear quite eazy...... espicially if that 65lt drum at the back of most cars is full of air and not fuel!!

I watched a guide put his boat in at Shady Camp (NT) one day. Its a very shallow ramp so he reversed until the back of his old Cruiser had water a foot above the back bumper. Quite bizarre watching the exhaust bubbles breaking the surface while he launched the boat.

[DICER]

it's gravity.... and of course a full car wash!
