At least Bede used the aft seat, which is a bit wider than almost all other gliders. The 2-32 is certified to carry 3 people, pilot in front, with two (up to 300# total) in that back seat. The type was used for rides/aerobatic rides at a lot of American glider companies. The sole Canadian one used to be at York soaring, & used for rides & spin training, but is now privately registered.
