Whale versus catamaran

[dirkdig]

The system of survey in Vic is a total joke,some of the absolute pieces of crap that are in survey should be taken to the tip.
As they got survey maybe 25 years ago the annual inspection is all they need to show its as it was at first survey date,no real relevance to its state today or real condition.

Probably very well. As the boat will be moving so slowly it would give the whale ample time to get out of the way.:-)

Steel hulls move through the water between 16 and forty knots, I dont know whats slow about that,

80,000 ton ships travel around the 30 knot mark,

I guess it was my failed attempt at humor. I thought the smiley face would give it away.

[Mr B]

I assumed it was a humourous attempt at a funny,

But some people do think steel hulls are slow, Not realizing a destroyer does 50 knots and weighs 6000 tons.

Most people I tell that I have a 40 foot steel sailing Cat think it is a wharf with sails, = Slow,

Vic survey rules are retarded.

To take your surveyed yacht out the Port Phillip heads, you have to write to them any take it out for however long you want to be out there. Eg. if you want to go to Refuge Cove or Tasmania for a week, it has to come out of survey. That one is supposed to be changing some time soon, luckily.

If that was an aircraft for example in the charter category, you'd have to take it out of charter to take your friends for a fly further that you would on a charter ... stupid.

Steel boats are considered slow because of the weight of the construction. If the steel destroyer weighing 6000 tons was built out of foam composite and weighed 4000 tons it would be faster if using the same propulsion as the 6000 ton destroyer. Not that anyone would want to build a destroyer out of foam core.:-( As far as a steel catamaran, if you can keep the weight down to equal a foam composite cat then why wouldn't it be as fast? Question is can you build a steel cat that light.

It actually has a small "crash bulkhead" in the bows that is above the water line.

Perhaps if you were to provide details and a picture of this miraculously lightweight steel catamaran peoples opinions could be swayed.

My steel vessel cruises at 6.3 knots. Most everyone passes me unless becalmed. So, your comment was appropriate for me.

Hi All,

we're not long back from Hervey Bay where we had 3 whales playing around the boat for over 1 and 1/2 hrs!! They came unbelievably close but not once did we feel them touch the boat. On our sail home to Lake Macquarie we'd motor sail at night to make some noise so that the migrating whales would hear us coming. During the day if we were motor sailing they seemed to go deep as we approached and would surface some time after we'd passed. I think you have to be fairly unlucky to hit one.

Regards,

Brian

Cool shots Brian!

Thanks for posting them!

I have heard that an echo sounder will alert whales to your presence. Any one know if there is any truth to this?
We hit one once sailing in the Canaries and would like to avoid the experience again!

Nice one
Good to see when on a sizable boat.

Had a sounder and a 2 stroke motor running here.

They didn't hit me, but they didn't run away either, rather they actually followed us around for about 20 minutes
