Interesting - my experience of Wayfarers was the old non SD versions. Our club had several - mostly used for training Safety Boat Coxswains. As you say, there were reasonably stable after a capsize - unless you got the water in them sloshing about. As a schoolboy at school, it was the GP14 that we used. At home, my family had an old Heron. So I like to think that I came up through the classes. And eventually ended up as Commodore of a large inland sailing club.It is. I own a MK2 SD. It is self draining, other models are not self draining.
It was designed to sit on a mooring and rain and water splashing in would drain out through Anderson type bailers. Unlike other Wayfarers of this age, the floor of the SD was moulded in GRP which created a sealed void underneath the floor. The floor is above water line. The Anderson type self bailers sit in a floor recesses, in the normal position in the hull. When left on a mooring, the Anderson style bailers are left open and rain water, spray from waves, drains out. That was the whole objective of the SD, which was aimed at dinghy sailing schools that kept their boats on moorings.
The problem with the SD, is when righted, from a capsize, the water level is higher in the boat and the void space below the floor continues to provide buoyancy, as it is sealed. This means that the boat is very unstable when righted, unlike a standard floor Wayfarer where the water sits both below and above the floors and the hull is not that unstable when flooded. To address this, many sailing schools (that capsize a lot), added the tunnels from above the sealed floor, through the aft buoyancy chamber and out the stern, sloping downwards. This meant that water in the hull after capsizing could be dumped out the stern quickly. Without this feature, bailing had to be done by hand, with a high risk of tipping the boat over as the water sloshed to one side.
I taught dinghy sailing in both the standard Wayfarer and SD, and later bought an SD from a sailing centre and cruised on it, I still own it.
The Wayfarer Association used to have a pdf leaflet that could be downloaded that described all the model variants and their features, but I can't find it on the Web Site.
