I agree that a self bailing deck would be an improvement but its not a simple retrofit unless the deck is substantially above the water line at the stern. You have to have a greater distance from the chine to the gunnels for a self bailing deck to drain and not have water back up if people are standing at the rear of the deck. If the scuppers are not well designed there can be problems with them and they will not drain huge amounts of water all that fast. Look at how small some of these drains are.
Also they should improve the whole engine compartment design to keep water out because of the predominance of inboard/outboard designs and raise up the batteries to keep them from getting flooded.

As far as I know, self baling cockpits are an EU (CE certification) requirement since the early 1990s. Sundowners were sold here in the mid to late 1990s ( I had a 1999 one). US ones are bound to be the same as far as floor height above water level. My 1999 one had scuppers connected to hull outlets via the sponsons; to be honest though, the scuppers wouldn't have let an awful lot of water through per second, even if they were not blocked by normal debris.

My 2004 Sundowner has quite big scuppers and outlets so the cockpit would drain a lot quicker than the 1999 ones would. there's no physical reason the later setup wouldn't fit an earlier boat

My 1999 sundowner has them to. They also help in waves.

If people didn't this board would be dead! It gets pretty thin for posts in the winter...
