The IGC voted in 2005 to reinstate a modern Two Seater Class with a span limitation of 20 metres and maximum all-up weight of 800 kg. This class has no relationship to the 'old' two-seater class, as it targets the high performance trainers that have been steadily gaining in popularity. Their smaller size sets them apart from the Open Class two-seaters which are very expensive and require experienced crews. The 20 metre two-seaters handle and fly more like Standard Class single-seaters and cost little more than half the price of an Open Class glider.
