Newly rescued DS1...and the cockpit drain

I picked up a Spindrift DS1 last summer and finally got it in the water today.
Upon splashing I immediately noticed water rushing in from the drain hole in the back of the cockpit. it settled down a bit when it got level with the water and not angled from launching off the trailer.
With one person in the cockpit, there's probably about a gallon a minute flow into the cockpit. If there's no weight in the boat it kind of drains back out if you're lucky. Most of the water accumulates near the low spot at the centerboard trunk.
From all the reading, it seems like some of the DS's have self bailing cockpits. No drain plugs came with the boat, and there's only one drain, there's no bilge drain, just a cockpit drain. And in fact, no access to any kind of bilge at all.
Edit: I just found the Spindrift manual and this classic line tells the story:
"Make sure the drain plug is closed prior to sailing". But the question remains, if this can be made better.
Here's me, in the back of the boat after a good scrubbing:

Here's the drain hole. Didn't completely scrub it squeaky clean yet... good enough for government work!

Also,
Obviously the main block and cam cleat is for the jib... what's the second smaller block and cam cleat for (the smaller one is towards the stern... traveler?)
Right now the traveler is just a line tied between two through-holes in the transom with no cleats, blocks or other adjustment points.

This is the logo/model to maybe help you guys ID this boat. (pre power-wash.. it looks much nicer now!)

Also, what the heck is this thing? Jib downhaul? Some say it might be a jib halyard tensioner (Also pre-powerwash... that top deck is clean enough to eat on now!)
Harken magic box
The working end is connected to a wire and a shackle. There's already a cunningham internal to the mast, so it's not one of those.

So... I found this... the go-to self bailer

Where does this get mounted? Is the hull thin enough to put this right in the middle of the boat near the centerboard, since the water pools here? The design of the bottom would require a bath tub amount of water to fill the cockpit before it will REALLY self drain.
What kind of drain plug is this? Is there such thing as a self-bailing drain that's horizontal instead? At least it'll let water out in a worst case flooding event, and will keep the water from coming in.
I would have left the images as img tags, but I uploaded original images at 2218x4656 and this board doesn't auto-resize...
