A few weeks ago I went out with 4 kids aged 2 - 4, plus parents. At some point 
the extractor fan suddenly speeded up. The battery isolator switch was found
to be at OFF; I strongly suspect one of the kids moved it. This little prank 
blew up a capacitor in my VHF, cooked another couple, blew the fuse 
(fortunately), and also blew the fuse in a depthsounder. I happened to 
have an obsolete but working radio & depthsounder on board. A subsequent 
experiment revealed that the nominal +12 supply went to about +20V and the 
engine continued to run happily. The radio used 16V capacitors. My old Seafarer 
MHD log was unaffected, as was my Loran. I *think* the Loran was turned on.
After replacing fuses and capacitors both casualties are back in action.

I only have one battery, and my isolator is a simple switch.

As a preventative measure in case it should happen again I have put a
rectifier across the isolating switch (if the switch is opened it should
prevent the supply rising to more than a volt or so above the battery 
voltage, while only allowing a few microamps through when the engine is off).
I have also fitted a 16V power Zener on the radio side of the fuse, the idea
being to stop the radio supply voltage rising above 16V, by blowing the fuse 
if necessary.

Anything like this happen to anyone else?

I'm looking for hard information (published design specifications, etc.) 
that compares real and design accuracies of GPS versus LORAN. Something
that mentions current and future levels of implementation (how the number
of satellites affects accuracy), along with an idea of the timetable for
new
launches, would be ideal.

Also, I understand that GPS is sponsored by DoD and LORAN by the Dept. of
Commerce. Has DoD made any form commitment to make GPS available to
non-military receivers over the long term? (I know about the civilian
error
codes--how likely is Defense to turn the whole thing off in times of
crisis?)
It looks as though the system is becoming very popular for a number 
of applications--Motorola is including a GPS interface in their new mobile
radio computer terminals for automatically tracking vehicle locations. 

If you can provide pointers to titles and especially where I can find
them 
I'd be very appreciative. Unfortunately, although I have news access I
don't
have an email account, so I'd prefer posted answers.

   Never seen one, but can guess what they must look like.

   Lots. Heeling the boat to decrease its draft will no longer work for you.
The wings, assuming they bolt to the bottom of the keel, will increase the
contact area with the bottom and will make it more difficult for you to
motor or kedge off as well. The likelihood that you will damage the wings
in a grounding is high.
   What are these things made of? What do they weigh? How are they attached?
If I were to design wings for a boat keel, I think I would make them out
of some stiff yet resilient plastic to avoid some of the above problems.

>3.  Does it help my pointing?  compared to the board up?  board down?

   Compared to board up, probably. Compared to board down, probably not.
Keel/centerboard combinations are surprisingly efficient when working
upwind, falling somewhere between deep fins and wing keels in pointing
ability. The main purpose of a wing keel is to prevent the flow of water
from stalling over a shoal fin. It works as an "end plate" rather than
a foil.

>4.  Does it hurt my overall speed/handling off the wind?

   Maybe a little. More surface area to produce frictional drag compared
to the shoal keel with the board up.

>BTW:  I'm planning an extended off shore trip and want to avoid the banging
>and unreliability of the center board - this is one option I've considered.

   What about making a set of bushings to limit the sideways travel of
the board? That might solve the problem, too.

It sounds about right unless you have an oil-injected motor.  (I can't
remember which year that they switched over.)  We used to be able to
troll a lot longer with Quicksilver (tm) oil than with generic oil,
but I still think that we were changing plugs after about 20 hours of
trolling.  Also, we found that NGK plugs lasted longer than Champions
for trolling.

One good reason not to is that the group (as far as I know) doesn't exist.
If you like, read the info in the news.* groups. You will find that
creating a rec group requires something like 2/3 majority of the votes

Are there 100 folks out there who are so close minded that they only

Good choice.  Your skipper did exactly the right thing.

You example is perfect for demonstrating when 32.1 should be applied.
If the bow of S is going to hit the side of P then S must
try and avoid the collision.  In the previous example, P's bow
hit S on the side and application of 32.1 is generally inappropriate.

       I stand corrected. I just called a local Mercruiser dealer, and the
price for the complete v6 package (not installation) is $5500. The V8
package is $6000, so in the higher horsepower ranges there clearly is
a big price advantage for the I/O.  When I priced Johnson 140's in
'89 they were $6400, so I guess they're going up fast.

Fact is Bayliners are not a finished or fine piece of machinary.If you
compare them to just about any boat on the market & they don't stand a
screaming chance in heck of being a boat I would ever consider
purchasing.Well at least a 21' open bow type boat.

I did however, after much dilberation purchase a 1992 Four Winns 200

n defense of Bayliners:

I have a 20.5' Bayliner hardtop Trophy ('87).  It is a great little 
boat.  I run it in Puget Sound salt water.  It is economical to run, 
using about 4 gal/hr with two of on board going at 19 knots.  
It looks great.  I have had people ask me if it is a new boat.  It 
handles just fine in 2 foot chop (it may do fine in ruffer seas but I 
am not brave enough to try it out.)  
I love the little boat - for me and my husband and our modest income 
it's great.  When we were looking for boats the Trophy model was way 
ahead of other type boats in price-vs.-benefits.  The next nearest 
boat in benefits we wanted was way beyond our budget and had higher 
running costs.
I am sure it wouldn't do well if we ran it over rocks, beached it, 
rammed it into docks, etc., but we don't want to do that anyway.  We 
use the boat mostly for camping and crabbing.
As far as access, the only item I haven't figured out how to get to is 
the center bilge pump.  (The center bilge pump works fine so I haven't 
been very motivated.)
I suspect Bayliner's are like anything else - it depends on how to 
treat them and take care of them.  Here is what we do:
...We run the boat at a modest RPM, not at maximum.  Bayliner 
   offers Trophy's with bigger engines but all that does is 
   increase your running costs exponentially and 19 to 25 knots 
   is fast enough for our purposes (and our pocket book).
   After each trip we clean out the fresh water cooling lines 
   and scrub the hull top to bottom.
   We keep wax on the boat at all times.
   The boat is kept in dry storage not sitting in salt water.
...Any repairs are taken care of immediately and maintenance is 
   done on schedule.

Happy boat hunting.

I'd like to know if anyone has any ideas on the ill effects of using a
degreaser in the bilge of a boat.  I have purchased some GUNK brand
automotive engine degreaser.  On the label is warns that is can damage
paint and melt petrolem products.  I hesitate to use on on my fiberglass
runabout.  I have a 17' Winner open bow with a Mercruiser 140HP I/O.  The
problem I have is that water in the bilge gets greasy.  Then it runs toward
the bow, through the drains, into the ski locker.  This tends to get my
skis greasy.  I'd like to degrease the ski locker and bottom of the engine
bilge.  Does anyone know if there might be any ill effects from doing this?
I certainly don't want to melt my fiberglass or any seals.  If someone can
reccomend another product that is designed for boats, or otherwise safe to
use, I'd be most appreciative.  Alternately, if anyone could calm my fears
of GUNK degreaser, I'd likewise appreciate it.

If you could send me email, that would be better, as I have a hard time
keeping up with all the newgroups AND getting work done.

Thanks much,
