At that speed don't you mean 'knackered knackers' ???Originally Posted by Jabba_
That E-TEC has obviously got way too much poke mate, better disconnect that NOS and unplug a couple of pots, 4 cyls on straight ULP sounds heaps enough. Otherwise how can we slow old 42kn boats keep up with you to check out you knack knack's?
Wise words PP - myself and a couple of mates are doing this in a few weeks with Bill.
From what I hear from people that have done it, it is the most valuable ~$450 bucks worth (full day) you can spend learning about boats & bars, let alone the 1st hand experience you get on all channels thru the washing machine during various tide states. It will be great & I can't wait!
Re pumps; I am amazed at the pissy little pumps supplied as standard on a lot of expensive offshore boats that obviously do bar work. Some would not even cope with a torrential downpour if the cockpit was left open to the elements, and if the scuppers that were not 100% tight, or any low transom penetrations for that matter, down she goes.

"Oscar, as others have said, you do need a decent pump, but if this is what you are relying on, no pump will help you, and you are probably the wrong boat in the wrong situation. I used to swamp-test boats for a living, and believe me, you don't want to be doing this on a bar, or worrying about whether your pump is big enough in this situation."
I agree ..have done this and scared myself witless...only way out of it if the volume of water is serious is to be lucky enough to make clear water then bail without capsizing...bilge pump pretty much irrelevant in this sort of marginal situation....by the time it is useful you will have saved the boat probably and it will remove the underfloor stuff wile you find the valium. All other things being equal you probably shouldnt capsize if the water is all below floorline, but your inertia will resist quick flotation so swamping is a readily available outcome. It is just too open a question. It's the crash when the green bit hits the floor behind you that gets the pulse going...! (5.0m Stacer at South West Rocks Creek 1989...not that I can remember.?)
In reply to my query on bilge pump size and some of the negative comments on the capability of my boat or expertise. I have many years experience crossing all SEQ bars, some of it working for the government.
What my concern was: How can people and companies build and sell boats supposedly capable of fishing off shore and fit them with totally incapable equipment for keeping those boats afloat – if an accident occurred the legal implications would be interesting. As someone said most of the pumps supplied are only because the law says you have to have one and are only of a size capable of dealing with a heavy shower, not what’s needed, mine included. There are many reasons you need decent pump/s besides being for a wave - hitting a submerged object like a container, reef, hulls failing and they do, etc.
My boat is fitted with pumps of 4000gph capacity because that's what I'm comfortable with - I was interested in seeing what others had, it appears my thoughts on other boats were correct – I have to thank Jabba for supplying figures – my impression from some of the other replies is - there are a lot of computer fishermen on our forum.
Sorry for the late reply, been taking advantage of the numerous sandies in the bay.
If your wiring is fitted correctly it wont short out, it should all still work with the batteries fully submerged under water....
But if you have that much water in your boat to start with, I dare say your screwed...
Jabba mate. You make some of the most outlandish statements
You are not sure if you have a couple of hundred litres or over a ton of water in your boat and then expect your bilge pumps to work OK with your batteries completly under salt water
You must have been doing 40knts in a 2m sea at the time just to make it interesting

OK, so the batteries or the wiring will short out when there under water...
Care to explain how diesel 4x4s are able to cross water that is up to the middle off there wind screen..

Yeah must be bull sh!t
A short immersion in fresh water is totally different to being submerged in salt water. I have taken my old petrol Landy through creeks where the water came over the bonnet with a tarp over the front and the motor did not even get very wet.
Batteries will work for a short period of time under water but rapidly lose cranking power

Spot on Horse!

Salt water is an electrolyte mate!

Alcohol doesn't agree with me, but i sure do enjoy the argument!!!
Horse, I totaly agrea that the battery and electrical will not last long in salt or freshwater, but a correctly set up your electrics and bilge pump will work long enough to get you out off trouble...
Also, some or a lot off off-shore boat have there batteries installed in plastic boxes which provides a air gap at the top, that will also buy you some time... I myself dont have this set up...
I had silly mishap when I first got my boat... I had a water leak in the hull that I could not find by eye. So I stuck the hose in the boat with the intention to only fill up to the floor board, and look for a leak.. Long story short, while it was filling up, I went inside had a beer and started watching the V8's and fell a sleep.. I woke up frantically remembering I had left the hose on.. the water was over the batteries because the jockey wheel was wound up... Good news was, found the leak. Small hole in the bow..
Also the bilge pump still worked, so did all the other electrics, and I was able to start the motor with water covering the batteries.....(at the time I only had the 750ghp)
I recon there was some water in this engine bay

I agree...the best bilge pump in the world is a scared man with a bucket!!
I have pump plus a self draning deck with fully sealed floor. But i still think the Skipper judgement counts the most.
