Arrrgggh. I get it . it was a good job thatwe were at the start of
the lake rather that 60 kms north at the end of the lake. At that end
the water basically flooded out of the lake floor and poisoned a big
area of saltbush grazing land. I was told it looked like a series of
mini tidal waves rolling across a paddock.

And then there's the water depth. What you're describing is how the wave
gains energy. The height comes when the rolling pin of energy moving thru
the water is thrust above the surface by the bottom.

For real waves, check out the south end of Lake Michigan when a north wind
has been blowing for a while. The skippers that come in thru the St.
Lawrence seaway claim it's worse than the Atlantic.

Wave size is determined by how hard the wind blows, how long it
blows, and the distance over which it blow (fetch).

A gale blowing for a day across a pond will not develop the same size
waves as a 20 knot wind blowing for a week across 1000 miles of open
ocean.

I was once crossing a lake that had a hard salt crust under 12" of
water. The vessel was an ARGO 6wheel drive amphib banana splits job.
On the way home we had to cross a deep channel (18") and got caught
in a storm front. the waves were high and steep enough to break over
the bow and low enough that we would slam onto bare salt, only to
have the next wave dump on us. we had no control at all and were
pushed onto a leeshore of sharp talus under a 6' cliff that the argo
couldnt climb.
Damage bill was half the cost of the Argo and it had been bent . It
was scrapped soon after. The Geologist and I got some lacerations and
bruises. The Geo was knocked overboard once, and between the bleeding
and the pain of laughing too hard, it took some effort to get back
aboard. No-one believed our explanation for the damage and our injury
report was faxed around the minesite as people thought it was a joke.
All this was before I ever owned a boat.

Your question's rhetorical, eh? We only got Moriarty, our Chinese Gaff Micro
launched at the tail end of last season, but we've been out under sail in
conditions ranging from 'lazy drifting' to 'over hull speed fully reefed'.

Derek
[looking forward to a much longer season this year]
Is it true that Alert is the only example
of a Chinese Gaff rig that has been sailed?

Has Oink been sailed yet?

Micro Navigator, with a mizzen seems
likely to be much a much different experience
than than the mainsail only version on Alert.

Within limits, of course. A vertical rock wall is would not be a
good place.

Typical power for a sailboat is 2 hp per ton. You need to round up a
bit for very small boats because the very small, high rpm propellors
on little engines provide push, but not shove, i.e. don't get you
started from a stoppped condition very well. A 5hp good enough for
my 1 ton Capri 22. The PB&F recommendation of 5hp seems very
adequate to me.

In fairness, Bolger tries to take the best of both ends when
discussing Alert. He brags about her exploits (miles sailed, oceans
crossed, etc) while noting that she is down 9 inches (or whatever)
from her designed lines, and has a permanent house that he would
have liked to veto. But he tends to put the burden of complaints on
the crew.

Melcher likewise seems to put the blame for various problems on
Bolger even though he started with a coastwise cruiser and took her
where she was not designed to go, and parted with Bolger's advice
when and whereever he took mind to.

Two indepentent spirits.

Peter
I think that the closer you are to dry land when you hit the bottom the
better your odds are of walking away from it. I know of a lot of spots where
the water is only a 5 or 6 feet deep 1500 feet offshore. When you destroy a
boat in deeper water there are a lot of pieces in the water with you that
will beat the hell out of you before you (perhaps) drift into shallow water.
All the best;

Any blow that would drive a boat upon a lee shore against its
skipper's wishes would also cause waves on said lee shore that would
likely destroy the boat and deposit its remains in knee deep water.
Any body of water that lacked sufficient fetch to develop such wave
wouldn't be any danger in any case.

I certainly concur with using a yuloh and that is true with shallow
draft boats. However if there are reefs and rocky shorelines around,
and a big surf - it may be safer for the boat to have the option of a
motor. It also gives one that ability to find shelter in "the calm
before the storm"... which often happens. So it depends a lot on
where you sail and how a good a sailer you are.

Susanne Altenburger recommends the 5hp 4 stroke Honda engine which
weighs 61 pounds. I believe it is about the smallest motor that
offers remote controls and an alternator.

Jason tells about that in mesg #35485, which I have kept a copy of.
With a LONG MICRO one can probably use the Yamaha T9.9 which has a
12 amp alternator and weighs 80 pounds - very heavy - but uses about
the same head as the 15.

LESTAT has had a 20 hp Merc with 6 people on board. This was only in
a river setting. However it does show how conservative PCB&F are in
their recommendations. They are considering more or les the worse
case scenario and are very responsibile for the safety of their
flock:-)

? that dang aluminum pipe of mine is not minimizing the weight in my
bow :)

I have a little 2hp honda, i hope that will do the trick. It'll be
hard pressed to fight a tide, here's hoping. I also am going to have
to shorten the shaft on my yuloh, not sure if the companionway is
going to wide enough to scull from the sole. I want to keep that
opening as tight on center line as possible. However i made the
yuloh long enough so as a little motion on the end provides quite a
bit on the blade, Just not sure till i try it out, may have to skull
from the deck. Sure glad the boat will have life lines. The micro's
configuration works real well for the yuloh, I have arched my
transom about 2 inches and the motor pivits under it and the yuloh
pivit centers over the outboard and just perfectly clears the long
shafted raised prop and is plenty clear of the prospective mizzen
placement.......if i had a larger motor say more than 5hp i would
have to raise the pivit point considerably.

Plus, I recall Bolger writing that with shallow draft boats [was it
Storm Petrel?] it would be a hard chance to find a lee shore
that, upon grounding, you wouldn't be able to walk away in
knee deep water

Bolger was supportive of my thoughts of using a yuloh for
auxilary power, versus an outboard motor, and he has not
recommended a large motor for Micro, rather he recommends
a small one. ...With the reason being that he wants to
minimize weight in the bow and stern of the boat.

Hi Bruce,

Thank you for sharing your response from PCB&F. The article confirms
what seems to happen with what must be annoying frequency for them.
Somebody makes design changes and then complains about the
performance afterwards as if the design was faulty!

And often do it after conferring with the designer who is against it.
Of course "junk rigging" his designs is one area of great annoyance
and the other is changing the configuration for preventing leeway -
like a MICRO with leeboards or something, not realizing the entire
design is a total sum of all the parts, each one very painstakingly
thought out.

"Of course, no boat the size of Micro can keep going against a gale,
if only because the drift of the surface water will take her to
leeward more or less. But I would expect her to hang on better than
most."

Nice words to hear, and also a confirmation for having a strong
relaible motor in case you end getting too close to that lee shore.

Cheers, Nels
I mailed a copy of this article on Alert to Phil Bolger and this is
the letter that he sent back to me:

[PCB's reference to 'mizzen' is obviously to the MicroNav rig, as
Alert does not have a mizzen. In essence, I think, Bolger is
explaining that in a gale at sea, the MicroNav could be headed up
into the blow, where the Alert could not.]

============PCB quoted below=====================
"Dear Bruce,

Sorry to be so slow answering yours of April 10. Things have been
hectic here in various ways.

As to Melcher's problems, he rig was a makeshift in the first
place. (to use as much of the existing gear and structure as
possible and he also did not make the most of it in several ways.
We did not at all like his sheeting arrangements when he was here,
and thinks at least part of his trouble would have been avoidable
with more thought.

We made the mizzen quite large since there have been complaints on
other designs that they are not powerful enough to keep the bow to
the wind, whereas it can be feathered (luffed) or furled if there's
too heavy a helm.

Of course, no boat the size of Micro can keep going against a gale,
if only because the drift of the surface water will take her to
leeward more or less. But I would expect her to hang on better than
most.

We will look forward to hearing of your trials and seeing pics of
her in action!

Sincerely,
Phil Bolger"

I don't think he had a mizzen as there was was some sort of autohelm
installed and the rig received a lot of damage through "accidental"
jibes. Sailing downwind with what is essentially a big cat rig is
pretty tricky at the best of times, let alone with gale force winds.

Having a mizzen and a storm jib would probably have saved a lot of
damage and "frayed" nerves. Perhaps the docility of the Bolger rig
makes one careless?

Cheers, Ne;s
Thanks for pointing us to this article John.
Has there been any reports about the conversion and results of
Alert's conversion to true Chinese rig?
I can see that for continuous offshore sailing, chaff would be a
major problem with the Navigator rig.
I imagine that the more docile rig would be better for cruising,
where speed is less important than ease of handling.

There's simply not enough info to understand the

Quoted here:

"To handle the strong winds, we reefed and then scandalized the main
by lowering the gaff's peak halyard," Jim said. "Even using a working
jib, we had excessive weather helm. When a lazy jack broke, it dumped
the whole works – boom, gaff, and sail – into the sea. It's turned
out a rather poor rig for offshore. I'm ready to convert it to

I wonder if anybody knows of PB&F's acknowledgement
and/or rebuttal to this criticism?

I suppose dropping the mizzein and main sails
entirely, and raising a small storm 'tri' sail
might be called for in that circumstance?

Or, dropping just the main and riding it
out with a sea anchor from the bow?
Good article with photos about Jim Melcher and ALERT. I found particularly
interesting Melcher's observations on his chinese gaff rig, and it's
suitability for offshore work.
