bilge cleaner?
The mechanic just winterized the boat and changed oil today.
Unfortunately, he left an oily scum in the bottom of the bilge. I know
this has been discussed in the past, but what is a simple, "green" way to
clean the crud out? The boat is on the hard now, but when it goes back in
the water in the spring, the bilge pump no doubt will discharge and out
will go what is there. What is is a good "product" or substance to
emulsify the scum so we can deal with it?

David, I would ask your mechanic what he used to clean up the mess HE made.
I would suggest that it is his problem.

A question I have been pondering, IF money was no object, why would I choose
say a 42' mono over a 42' Catamaran? To me the Cat design makes so much more
sense, lot more stable, capable of being driven more economically with
smaller engines, WAY more room.
Love to hear the list's thoughts

The next time you are on a cat, ask to see the engine room. Then think
about normal engine room maintenance.
It's really tight and if the engines are hot!!!!! You are screwed!

I'm not so sure about the stability, Mervyn. In large swells a Cat is going
to be at the same angle as the water where a monohull will remain upright on
the side of the wave.
I charted a power Cat in the Virgin Islands. I was surprised that instead
of leveling out the 2-3' chop I felt every wave TWICE.
Many Cats don't fit in a standard width marina slip and you have to take a
end tie for more money.
Otherwise, I like Cats. As with everything there are pluses and minuses.

Ohmigawd, Mervyn! Now you have done it! I see another loooong
thread coming! Clearly, mono is better than cat. Otherwise, why
would ALL trawlers be monohull? ;)
Duck! Here comes the experts!
With tongue in cheek, I remain on the sidelines...

A catamaran will not carry the weight of a monohull.
You can buy a self righting monohull, a cat is stable right side up AND
upside down.
If money were no object, you'd buy a bigger monohull and not worry about
the fuel cost.

Friends have informed me that my absence from the list has been noted.
I'm happy to say I am finally reconnected via a WiFi link.
New email address is 2elnav@netbistro.com
TELUS doesn't work here. Nor does radio or cable TV. Cell phone coverage is
sporadic.
We moved to the interior. Nearest town is 40 miles away.
Talk about having to be self sufficient. Its almost like equipping a boat.
Generator is on order and plans are being made to set up the inverter with
battery bank.
Meanwhile the gimbaled brass kerosene lamps and trawler lamps are being
cleaned up, polished and installed ready for use.
Thanks to the long range WiFi equipment I can now stay in touch, and even
Skype. < Smile>
The satellite option was twice as expensive.
Happiness is high speed internet access.

But all too often money is a very real concern.
With fuel costs in Canada approaching or exceeding $4.00/gallon I can see
why a cat would be very attractive.
Judging from Mervyn's area code, its my guess the 42 cat in question is
likely the PDQ42 built locally in Whitby.
The argument that a monohull can carry more is only true to some extent.
Regardless of hull type weight equals more fuel burn. Having a monohull
should not be an excuse to simply add more and more weight as if it didn't
matter.
I have seen posts recently about repainting the water line on some boats as
a solution to over loading. Not Good!
When equipment and systems are designed and installed, their relationship
to the DWL - design water line - is part of the design consideration. Bilge
pump discharge fittings are supposed to be installed above the heeled water
line according to ABYC. When you add weight and then repaint the boot top
higher on the hull, you have in effect compromised the original designed
safety factor. Overloading the hull has many adverse side effects including
greater fuel burn, changes in stability and righting moment etc.
Only by examining all the benefits and drawbacks for a given cruising area
can a realistic solution be found. In some area slip width is definitely a
limiting factor. Evidently this has not been a detriment to sales in all
areas.
Marinas and yacht clubs with boats kept on moorings doesn't pose a problem.

There are three things that we require on a boat, and most affordable
cats have only one of them at best: (1) plenty of space in the engine
room to get around the engine for routine maintenance and emergency
repairs; (2) a non v-berth island (or at least a semi-island) queen
berth; and (3) real fuel economy (around 2-4 gph) at cruising speed
without jeopardizing the engine(s).
Awhile back I had the opportunity to ride a 44 foot cat for a few hours.
The ride was delightful even in rather rough conditions, but it was
extremely overpowered with twin turbo diesels at a top speed of around
26 mph where it was burning over 40 gph! A master cabin with an island
queen and a 360 degree view outside the boat - incredible amount of
space. The "engine room" was about 6 inches wider than the engine -
total width - and in order to get to some of the changeable parts you
had to stretch out over the top of the engine! No thanks - even if I had
the +3/4M$ to spend on it.
Both monohulls and multihulls can suffer from the same design issues.
You just have to know what you require in a boat, and order your
priorities, no matter what the hull form.
