The factory wiring harness contains color-coded wiring, and the wires are
sufficiently large to handle the current that the factory intended on
having them handle.

The only other advantage of the factory wiring harness in most installations
is that the tube through which they pass the wires protects them from
chafing.

I have rewired a number of (aging) outboards to bypass/get-rid-of the harness
connectors, with no trouble except for the hassle at rigging time.  There's
probably even less reason to keep it when you have an inboard.

Well my particluar usage of boats is to travel to dive sites (normally
ship wrecks). Plus or minus 100 meters (nominal GPS accuracy with SA
turned on) makes a lot of difference in the amount of seabed that

I am looking at a sailboat as a liveaboard.  I have taken a close look
at the Cascade 36, and was impressed with the deck and cabin layout.

Can someone tell me about it's sea handling?  I'm never thrilled by a
fin keel, but I'm reminding myself that it will primarily be my home, and
then a blue water boat when I get restless.

I live on the Columbia River, but would like to feel comfortable going
over the bar, off-shore, and possibly to AK via the inland passage.

You responses would be very appreciated.  I'm making the move to get
equity in something instead of just paying rent, so this is a big financial
move for me.  I can't afford a big mistake.

I wanted to get in on this sooner but was called away from the key

times. the best experince came at the worst times. Heavy wind and a
failed motor. My boat was a CD Typhoon. I used the jib alone method.
This way By holding the jib sheet and tiller i could try (Succefully) to
power and drive as needed. I find that using jib alone means you dont
have to be concerned about a flying boom when you turn into the wind. I
hardest part was not getting into the slip but being able to drop a dock

practicing, but we rather be crusing, and leave the need to know things
untill we are saying to ourselves I wish I practised. more. Opps where

I second the GPS recommendation. Last Saturday, we sailed the last
event of the SF Bay ocean racing series, from Half Moon Bay to
San Francisco. Throughout the 20 mile course, in light winds, we
were in dense fog, with the visibility not more than 200 feet.
We approached the Golden Gate after dark and found, to our
great unease, that the Loran and GPS differed by 60 degress in
giving us headings to avoid Seal Rock, Mile Rock, Point Bonita,
etc. There was a wicked flood, too. We decided to trust our 
Garmin 50 GPS. It took us right to the south tower of the 
bridge, as desired. 

By the way, we won our division, PHRF (heavy), and the season
championship. Next: midwinter racing (sorry, other coast).

Advantages:  More cockpit space, Quieter running, higher top speed (on a
relatively fast boat), more responsive helm at low speeds.

Disadvantages:  Harder to repair motor in water, longer storage space
needed for boat, motor gets wetter, more stress on transom.

The SeaDrives place the engine closer to the transom than a conventional
bracket, so the transom stress is reduced and the motor doesn't get as wet.
On the other hand, the SeaDrives have a higher pivot, so the boat length
increase caused by tilting the motor up is greater.

The "motor gets wet" problem can be fairly serious.  I've seen a couple of
boats where the bracket-mount motor sat so low in the water that it would
frequently suck seawater in through the air intake openings under the
motor cover on the older OMC outboards.  This seawater would get sucked
into the air intakes, wiping out the powerhead.  While this is not a serious
problem with most bracket-mount installations, it it something to watch
out for.

 This topic came up over lunch today.  A bof <brother of a friend> is a
 geologist.  The accuracy that he needs is plus or minus 15 meters (within a
 30 meter diameter).  Establishing the exact position of a site is currently
 done by taking sightings from a benchmark.  Of course if there is no
 benchmark in sight you have to establish an intermediary benchmark and take
 a sighting from the intermediary.   Now picture this in mountainous
 terrain.

    My friend tells me he is considering buying a Rhodes 19.
    I've never sailed one before and I'd like to hear more
    about them.  Mostly, he would use the boat for daysailing
    on the Chesapeake with 1-4 friends.  Occasionally, he
    might overnight with a single friend.  He is an experienced
    sailor with lots of racing experience but he won't want to
    do any racing in this boat.

    This calls for a boat which:

	1. Is fun (and fast) to sail
	2. Moves well in light chesapeake breezes
	3. Has a big enough cockpit for 4-5 folks in a pinch
	4. Has a small enough draft to explore back creeks
	5. Has a small cuddy cabin with room for 2 sleeping bags

    The boat does not need to trailer often...

    How does the Rhodes stack up against this situation?  What
    other boats should he look at?

     Thanks!

Yes, they do produce lift, but not in the conventional sense.  They do
not attempt to `lift' the boat (this would actually negate the effect
of the lead being low in the boat).  What they do, when the keel is
loaded up with a large side load (especially true upwind), the keel
has a pretty healthy angle of attack (sailors call this `leeway').
This leeway angle makes the downward droop (dihedral) of the wings
produce lift on one side and down force on the other.  The net effect
is to produce a vortex in the water _opposite_ to that coming off of
the tip of the keel.  The two cancel out and the total effect is less
energy left in the water as a wake from the tip of the keel.

The aerodynamic theory involved is pretty complicated.  But if you
have noticed the little tip fins on the ends of 747 wings lately (the
747-400, the newest model), it is exactly the same idea.  The wing is
producing lift and the tip fin (winglet) is opposing the swirling air
from the wing.  total result is less drag.

As always, more span (more draft) is better.  Rules, moorings (channel
depth) and other considerations may make winged keels more common.

The rotation of the propeller. It's true of airplanes as well as
with boats. On one hand, you have the forces of the propellor trying
to drag the stern one way, and the rotating slipstream acting on
the rudder. Trying to fight this, are the forces generated on the
rudder via the boat's motion through the water. As you use more power,
the propellor's effect, relative to the motion of the boat, gets the
upper hand. A the boat speeds up, the motion of water on the rudder
starts to win.
 
Unfortunately, it seems like all the factors which favor the boat
getting on towards effective steering going forward seem to work 
against it in reverse. 
 
Most marinas will ask you your preference for slips, based on which 
way your boat backs down.
 
And a number of sailboats will not back down straight at all.
 
It all depends on the underwater shape of the hull, and where the  
propellor sits, as well as on the propeller itself. It seems, though,
that good backing is not often made a high priority in yacht design.
 
I suggest you learn how your boat behaves, and make the most of it. You really 
have to learn how to work with it, rather than fighting it.

Polyester was invented by ICI (Imperial Chemical Industries) in
England and marketed under the name Terrilene (maybe it was spelled
with a "y").  They licensed it to an American company (Dow I think)
who marketed it as Dacron.  

After WWII when the American ocean racers started showing up in

best material for sails: Dacron or Terylene (I think that is the
correct spelling).  It went on for some years until finally someone
wrote in to one of the magazines pointing out that they were the same
material.  At that point, the argument went the way of the great
"black decks" controversy of the 70's-80's.

Right, but sometimes it can be too accurate. We bought an Interphase Starpilot
a few months ago. It only used 4 satellites and the newer models were going for
6 so we got a good deal. I love it! We were anchored in Quarry Cove off Angel
Island. There's a pretty good current running here and this night the wind
didn't quit. We set out plenty of scope after watching 2 other boats drag, then
give up and go home. We set the alarm for the minimum. About 2 a.m. the tides
gone out and we're swinging a little wider and the alarm goes off. After making
sure we're not dragging, we set the alarm for more drift allowance. This
happens twice more until Richard decides if we set it any higher we'd be on the
rocks anyway. We called Interphase and they said there have been anchor alarm
problems with the 4 satellite model and it shouldnt happen with the 6. If we
send it back they will upgrade for $50 dollars and we should have no more
problems. This is where we found out that Starpilots are made by Trimble. It
was upgraded and back to us within the week. Great service! We haven't had a
chance to try it but I have faith.

You mentioned one reason, the cost of the fuel.  This is compounded by the
low capacity of CNG tanks and the lack of places to get them filled.   Most of
the problem is really one of market existence but when I did a stove conversion
I could see little benefit to a system that needed frequent fill at large expense
and difficulty.  It's even worse if you like to cruise.  Try finding CNG out
in the boondocks of Maine.

OTOH, CNG is supposedly much safer.  It is true that the stuff is lighter than air
and will disperse better.  However propane has a pretty good track record both
on boats and in shoreside installations.  I suspect that CNG isn't really that much
safer anyhow.  If the boat is closed up when a leak develops you could still get
hich gas concentrations.
