Heavy pilot - what glider to opt for?

One source of confusion on cockpit loads is that the airworthiness
requirement for certification under JAR 22 was (and I think still is
under
the current regulations) that, with basic instrumentation, the minimum
cockpit load must be not more than 70 Kg/154 lbs and the maximum not less
than 110 Kg/ 242 lbs. Most gliders, if weighed and weight and balance
calculations done, will have limits wider than this, in some cases much
wider. Some time back, the major German manufacturers developed the
practice of sending new gliders out of the factory placarded with the
70/110 kg limits, checking their weight and balance and calculating
cockpit loads on delivery usually enabled the re-placarding of wider
limits. This was a common practice in the UK, not sure if it was much
done
in the USA.

I think you will find that the upper cockpit seat limit is fixed by the
certification of the harness/attachment points which is why most gliders
have 110kg (242lbs) as the seat limit.
