High You All . As to the question about stability of a power trimaran--four years ago I rode on a 50 foot Tri from Naimo BC to Alaska  during a predicted log race.  The boat was unique, home built, powered by a GM 350 Gas V-8.  It did have one  big drawback--When an Ama caught  a wave the boat would turn and then  the other ama would catch a wave, etc, etc,.  The autopilot could not keep a coarse within 10 degrees!  Dave sends.

Hi Georgs,

Happy New Year to you and it was great to know that you will be manning
the chat page again, especially Power Catamaran World

It is thru your chat page that many naval archtects have revised there
ideas,
as a builder I have seen these ideas come through strongly over the past
years,
as they have also had a lot to add.

I firmly believe that the power catamaran market is ready to make big in
roads
over the next year especailly when the designers start designing a proper
power
catamarans and not a tradeoff from a sailing version.

Two reason, value for money and strong economics.

It is great to learn, as a boat builder, that building in the Far East and
Asia
is not going to be so cost affective as led to believe by many, and that
gives us all
a far chance.

Our project this last year was to rival the upper end of the semi-rigid
market, which no builder has attempted to do, and so being,we developed a
17ft  assymmeterical hull wet deck powered catamaran.
After serious cutting, slicing here and there and other major surgery we
finally
found the right formula, a Cat that can go at great speed with 2 x 40hp
motors, (1 gal per
hour per motor at 18kts) carry a large load, as in dive bottles, fish,
coolbox, 40gals of fuel,
and other supplies.
She is 65% foam filled, but still able to have huge dry lockers under the
deck as we have
used the flush wet deck high freeboard configuration with low side gunnels,
this allows us
to beach launch through the surf in most cruicial areas, without any danger
of being swamped.
She is stable, virtually turns on her own axis and surfs the waves easily.
Cat C offshore rating, 15 miles offshore.
As a Trailable cat weighing only 1600 lbs and priced all up with trailer and
motors at
$32.00 we are certainly going to give the Ribs a go for their money and we
think it
about time.

best regards
Tim  Aventure PowerCatamarans

Bill's reply to me the other day took me (reasonably enough) to the PDQ
website and while there I saw a picturesque scene of a 34-footer beached on
a lovely warm beach.  After momentary thought of wishing I was there (OK . .
. OK, it was many moments), I wondered about damage to the gelcoat to the
bows that doing such a thing might cause.    My father routinely beached his
25 and 28 foot Bertrams with no apparent problems, but I wondered if doing
the same thing with a 34 or a 41 power cat would be a good idea.

Assuming that we don't play LST (Landing Ship Tank) driver when we do it and
that we faithfully avoid rocks and coral, is there a practical upper limit
on the size of a boat when it comes to beaching?

John

I occasionally beached my 28 ft cat, and here in Alaska we don't have the
silky white sand you see in the sales brochures.  My boat was aluminum, but
in either case you're more worried about scraping off your antifouling paint
than damaging the hull.

Bottom line - very possible provided you exercise reasonable caution.  You
don't want waves grinding the boat on the beach, etc.  And my cat had
outboards which I could raise - with the PDQ's shafts you'd have to find a
pretty steep beach that prevented your props and rudders from damage.

But in reality, beaching a big boat is a pain.  You constantly worry about
getting stuck due to tides or waves or wind.  You're appropriately nervous
about other damage occurring and will be constantly fussing with it, but
none of the rest of the beach party will share your concerns and will find
you annoying.  Boarding the boat from the bow isn't practical w/o a ladder,
and you won't want to bring it in stern/prop-first.  Hauling the cooler of
beer and umbrella and lawn chairs to the beach means you have to hump them
around to the bow on the narrow side decks.  You won't find it nearly as
relaxing as it looks in the brochures...

Of course, there are places where people just wade to the beach I guess, so
'close' is good enough.  We don't do that up here in our 45 degree water.

Better to just get a very capable tender with a convenient launching system.
Then anchor your big boat in front of the beach and enjoy the view of it
floating in the water where it was meant to be.

We have beached our Endeavour 44 Trawler Cat on occasion to clean the bottom
of barnacles and change the zincs on shafts and rudders. Did this is in calm
water. I wouldn't recommend beaching any boat on the beach if there were
swells or waves coming in from behind.  We put out a stern anchor just prior
to beaching.  After beaching we buried an anchor on the beach.  This practice
stopped us from swinging around while beached. It kept the stern stable and in
deeper water for maintenance.
CAUTION!!!  Be very, very carelfull and avoid getting underneath the boat
while your beached. Your First Mate or Admiral should be standing by when
cleaning your boat in shallow water. You could get yourself trapped underneath
and get crushed or drowned.

Taking the dinghy onto the beach is not a bad idea!  For recreational purposes
this is what we do. Our dinghy launching procedure is very simplistic.

Have a great day at sea or anchorage.  Enjoy the day.
