My wife and I were discussing safety equipment for our new, to us, cruising
boat, an Annapolis 26, and the question of what type life jackets would
we need had us a little confused.  We have been racing a Thistle for
a number of years and found that the Stearns & Foster Type III's worked
well with the limited space under the boom.  Now that we can stand up when
tacking, almost, and our sailing is weekends, day sailing and week long
cruises on the Cheasepeake Bay, are these adequate for us or should
we look into something more?   Any help from the more experieinced cruisers
would really be appreciated.

Thanks in advance

i am considering purchasing a set of one-piece foulies, and would
appreciate any opinions on them.  i race on san francisco bay, as
foredeck, so need max protection.  nothing like getting doused with a
ton of green water in the middle of a spinnaker jibe with the wind
blowing 35 or so.  racing sf bay also rarely admits to getting too
warm, so the issue (as i've been told) of not being able to take off
your jacket and cool off is not a driver.

my questions:  

	* what are the advantages and disadvantages of one-piece suits
 	  versus bibs & jackets?

	* anything to especially look out for (either on the positive
	  or negative side) when buying?

	* what about brands?  i've found suits from douglas gill,
	  patagonia, musto, timberland, and henri lloyd, with a range
	  of costs from $150 to $400.

	* any especially good places to buy?

A short while ago, someone asked about buying a recreational/ski boat (I
think it was in the 17-20 ft. range). 

Does someone have a summary of responses? I didn't save any of them because
at the time I didn't realize how close I was to deciding on purchasing a
boat. However, I've taken the plunge, and am now in the process of filtering
through a ton of makes and models! I'm looking primarily for a recreational
boat I could use for skiing, knee boarding, tubing, general enjoyment, even 
fishing if I got the urge!

I was at a Boat Show in Oakland this weekend, and found some interesting deals,
including:

1992 Chris Craft CONCEPT - 18 ft., trailer, $17,000 out the door (including 
   dealer prep, tax, license, etc.) - OMC V-8 5.0 High output engine, 200 hp,
   supposed top end ~ 50 mph

1992 Sea Ray Limited, 18ft. - $15,995 plus tax, license, etc. - V-6, 175 hp,
   supposed top end ~ 50 mph

1992 Sea Ray (can't remember model!), 19ft. - ~ $21,000 + tax, license, etc. -
   optional 350 V-8 (included in $21K price, could have gone less engine for
   less money), 260 hp, top end 60 mph

1992 Four Winns 180, 18ft.  - ~ $15,995 + tax, license, etc. - 302 V-8, 200 hp,
   supposed top end ~ 45 mph

1992 Four Winns 190, 19 ft. - ~ $20,000 + tax, license, etc. - 351 V-8, 240 hp,
   supposed top end ~ 50 mph

Any one have any good or bad experiences with any of these boats? Any
suggestions? Should I buy new or used? (I think that is what the past posts
dealt with...) What could I pick these up for used? (say about a year or
two old)

From tidbits I picked up here and there, the pecking order of quality is
probably: Sea Ray & Donzi (tie), Chris Craft, Four Winns, Bayliner..... (I
am sure I missed some!)

Final note: I looked a pure ski boats (like Mastercraft, etc.), but do not
want one due to the limited use (couldn't take into the bay, rough water, etc.)

Thanks!

Allan

Grease is oil in some sort of matrix.
It is not the oil that is water proof, but the matrix. The standard
grease matrix is some sort of soap, which absorbs moisture. Other matrix
material won't absorb moisture, and so is water proof.

BTW, the engineers I've talked to call it soap, but it isn't clear
if it is 'wash your hands' sort of soap, or just SOMETHING that they call
soap.

Hope this helps.

As has been pointed out many times before, and I'm sure many
to follow, the oil in the gas is not going to hurt your
car.  Carbureted, fuel injected, it does not matter.  Note
that in the past it was standard practice for racing 
4-strokes to put a little oil in the gas to lube the
top-end (piston. cyl, and valve guides).  

On the other hand, I would probably not put the old fuel
in my car.  I would use it in my lawn mower or chain saw.
This is not because the fuel has oil in it.  It is because
the fuel has already been deemed less-than-perfect.  I don't
mind being stranded with lawn half-mowed or a tree half-cut,
but I consider automobile failure at least as large of a
nuisance as boat failure, though perhaps somewhat less dangerous.

But, if you really want to just be rid of it then try the
yellow pages under Waste Disposal.  As a test I just tried
it.  I called the first of seven entries.  They said "No,
we don't do that, call these guys".  So I called those
other guys and they said sure, no problem, no charge,
drop it by.

But the boats have electronic instruments aboard. What are these powered by?
Photoelectric solar cells? 
Does the prohibition of "stored energy" mean energy used for propulsion? Or may
energy be stored for other purposes? Enquiring minds want to know...

Maybe S&S did go past head-to -wind, it was tough for me to see. But for Kanza
to have to steer the stern away from S&S's bow by bearing off, to avoid
collision, K anza would have had to be ahead of mast-abeam position. All this
appeared to be within the two-BL circle, so which set of rules supercedes?
Definitely back to the rule book for this sea-ignoramus.

I think, after seeing the collision about a zillion times from a
zillion angles, that I agree with Isler and Jobson:  it was a simple
windward-leeward, Conner had right of way, and right to maneuver
(luff) and Melges failed to keep clear.

In this situation, the jib is not a reliable witness as to whether
Conner tacked.

Melges should have tacked earlier, dead ahead of Conner, so Conner
couldn't get into a leeward position and still make the mark without
tacking.

I also think it would help the on the water judging if they had a
person on each boat, like in some of the other match racing events.

Racons are pretty specific to radar.  They are transmitters which respond
to being pinged by a radar beam by emitting a morse-code character(s)
which uniquely identify them.  On a radarscope they light up very 
distinctly.  They are a super aid to navigation since they give you
a rough fix with no foolin' around.  They don't figure large in the
recreational boating literature since most boaters don't have radar,
though more do all the time.

I'm not sure how expensive they are.  The Coast Guard pays for them.  The
response time is *very* fast.  But then again, that's electronics for you.
They are not reflectors though, they are more like transponders.

>Let's see, at the speed of light .... yup, that is very fast !

I'm sure there is some error in the range but it aint much.  Racons are useful
at long range.  By the time you get so close that the delay error matters
you can probably see the thing anyhow.

>Any additional info would be appreciated. Thanks.

Next time you're shopping boating related books, look for something on
radar navigation.  It will fill in the details.  If you really want
I'll look up the titles I have.
