Hi Mike,

While speculating, you may not have considered a setup such as I have. I
believe it may allay some of your fears. My single Lugger drives a 165A Balmar and
a hydraulic pump for the steering gear. The Yanmar pony engine has an
identical alternator, and I will be retrofitting a second alternator to it soon. The
Yanmar is used, once a day, when at anchor to make and heat water and to
charge the batteries. This useage assures the pony is well-loaded and isn't
neglected.

In the finest tradition of PNW fishing boats, it's a very simple setup. There
is no genset. Everything is DC, except the nav computer and the microwave.
Naturally, there is no AC, which is patently silly anyway. Before anyone flames
me for that, consider that despite living most of my life in Vermont, I
adapted easily, years ago at the tender age of 50, to sailing in the tropics for 3-5
month per year without AC. Funny how humans lived in the tropics for
centuries without it, and how it's such an expensive and PITA  "must" for trawler
owners.

What would you propose as an alternative to the pony engine and its "fragile"
stern gear? My boat sailed in the Bahamas, Central America, Canadian
Maritimes, the US East coast, the PNW, Alaska, the entire West coast of the Americas,
the Chilean canals, around the Horn, the Falklands, Brazil, and Caribbean over
the 10 years the PO had her and never had a problem with the pony's stern
gear. I'd say that's a pretty good record.

Regards,

Small engines with small shafts outboard of the centerline are vulnerable
and weak. I am sympathetic to the get home concept, but would rather have
the main working than any wing engine filling in.
I am suspicious that the wing engine leads to complacency about maintenance
of the main engine. This complacency is subtle and may be a problem even
for owners who are nominally pretty rigorous about maintenance.

You can buy a heck of a lot of spare parts, spares kits, tools and pre
installed parts for the price of a wing engine with shaft, transmission,
propeller, strut and all of it's combined maintenance. The wing engine
requires less thought and experience and in a sense is a no brainer.
But...well, you've heard by observations.

I think many of you have misinterpreted my comments. But, here is some
clarification. I do not think that any single configuration of engine,
wing, etc. is the solution in all cases. Every single decision has it's
advantages and disadvantages.

If you put in a wing engine and don't maintain the main because of
complacency and the main fails, you will have been confirmed in your
conclusion to have put in the wing in the first place. It is difficult to
tell whether the wing engine is more or less to susceptible to damage, than
the main is to a catastrophic failure.

I have 40 years of professional experience with all of this. My conclusions
are that a single main may be preferable to a main and a wing. At the very
least, those who have less experience are less in a position to make the
argument one way or the other. But, they are entitled to their opinion. I
consider my role in all this to challenge the assumptions that a wing
engine is the solution in all cases.

Since I have the experience to back up my argument and since I believe in
that experience, it would be intellectually dishonest on my part to argue
otherwise. What anyone else does with the information and my opinion is
their affair. But, I make it a point to be frank. By the way, I use my own
advise. This is not one of those cases where you should do as I say, rather
than what I do in practice. After all, I end up with single screw boats
that almost never have wing engines or any get home device.

Regards,
Mike
