So I have good news and bad news about adding a "T" handle drain. There is a flat spot on the bottom of the hull in the '08 lsv but it is not accesable from the top through the tank. The only thing I could figure out would be to add a drain that you accessed from the underneath the boat. There would be limited drag on the plug as it is located between the tracking fins which would help to divert water around it. The tank is raised about 1" from the bottom of the hull so you would have to be careful when drilling through not to hit your gas tank. This is probably the way I will go, while not convenient it at least allows me to drain the water when i want to without removing the floor and vacuuming it out.

Here is a pic of the gas tank on my '08 LSV. Notice the hole towards the bow in the tank.

The good thing is that the hole is large enough to fit a "T" handle and your hand in to drain the water as this seems to be the lowest accessible point of the hull.

The bad news is that there is also a flat spot on the bottom of the hull, but it does not line up with the hole in the gas tank. It is smack dab in the center of the gas tank were no hole is available.

The spot on the bottom of the hull that lines up with the hole in the gas tank is just to the front of the first tracking fin. The problem here is that this is also the place were the hulls deep "V" shape begins. Not sure if you could put it off to one side of the center line or how it would affect the structural integrity of that part of the hull.
