Using thermals to climb?

You can say that again. Living on a 14nm x 30nm island, you can imagine
just how much marine air we have.

However, I have had some long soaring flights here in the Blanik. I just
bought a share in a Schleicher Ka-8 (which will happilly thermal in a
fairly tight turn at 35 knots), and I expect to be able to do my Silver
duration this summer without too much trouble :-) People often are
attracted to these hot glass ships, but forget how much fun and how good
a wooden glider soars.

Dylan,

Ka-8 and "happily thermal" in the same sentence - wow! ;-)

And what's wrong with that?

I spent too many hours in Ka8s to be one. They are great - if you don't
want to go somewhere.

My idea is to use thermals to climb (much)faster like gliders do.
Is this a stupid idea?
If my idea is not that stupid how do I find thermals and how to use
them properly?

Well, you have had quite a number of good answers already.

I'd just like to point out the safety considerations, collision
avoidance in particular, if we get powered aircraft looking around
for thermals, and perhaps circling in them while there are also
gliders in the area doing the same thing.

The visibility in turns out of your average light power plane
is way inferior to gliders (in your case, with the Rallye
you may be a little better off on this than the Cessnas and
Cherokees but still), your airspeed will be different than
that of the gliders and you might be less maneuverable in
that situation (turning tight and just above stall speed).

Assuming you want to use the thermals to supplement your
engine, as you said, you will be climbing under power, at a
higher climb rate than the gliders and coming at them from
below, where it is more difficult for them to spot you.

So if you plan to use thermals, make sure you are aware of where
the gliding sites are, in what areas gliders are likely to be
flying, and remember to keep a good lookout, even more than usual.

Gliders are much more difficult to spot in the air than power
planes. They will normally see you more easily than you will
see them.

It would also be good to find out what frequencies are used by
the gliders, listen in and let them know where you are.

Not that I'd like to discourage you, but this is something
I thought should definitely be mentioned.

As somebody else alredy said, it is a very good idea to take
some gliding lessons - I agree with that, and would add that
it is good for safety as well.

Where can we get a list of these frequencies? Are they published?

There's a glider area near me (Jean, NV) & I was surprised
to find that they weren't using the frequency of the nearby
airport. But of course I can't remember what that frequency
was....

Great summary, btw. Lots of good stuff to think about...

123.3 and 123.5 are standard for gliders. They're used for
contests, local flying and XC.

only use 123.3 and 123.5 when out on cross country..
we use the local airport freq (0L7, Jean NV 122.9) when staying in the
valley

but not all gliders carry radios...

That's interesting. I presume 122.9's the CTAF freq for
Jean? Around here (Northeast U.S.), gliders will seldom use
CTAF unless they are entering the pattern for landing, so it
would be hard to determine there was any glider flying with
that freq. It's way too crowded a freq. for typical glider
communications, so gliders will go to 123.3. or 123.5 even
when staying within the 10-15 mile local area that keeps
them within glide range of home.

Tony, it's 122.9 and we live on that freq..
