I've just acquired a 1999 130 Sport. It has three [through-hull] drains. I understand the one in the stern and the one which drains the storage area in the bow. But what about the one under the helm seat? I'm not sure of the purpose for that. Where does it drain to?

There are no interior bilge spaces, so through-hull drains lead overboard.

Thanks for the reply. I just went outside and looked again. The one I'm talking about is indeed "under the helm seat, and you're right, it goes clean through the hull. If the boat were in the water, removing the plug would cause it to fill up. So I think the purpose is to keep it drained when stored on a trailer.

If the boat is actually a 130, then there is one located directly below the helm seat.

I have a 2001 130 SPORT and it has the extra drain under the seat also.
I have also wondered what its purpose is ?
Another quirk on the 130: some have a brace under the helm seat to the floor, some have it under the console seat,some have none at all like my 2001 130. Both seats should have center braces as both of mine are sagging, and the helm seat has a lot of bounce to it.

I have a 2000 13 Sport and it has the drain under the helm seat, too. It is useful for draining the boat when it's sitting level because the forward cockpit is stepped down from the aft cockpit and ends up being the lowest point in the boat. If I stand in the right spot I can drain my boat completely with this plug out. I think it's actual purpose is for letting the rain drain out when leaving the boat moored. I haven't tried it, but I'm told you get a nice shower if you remove this plug when underway.

I leave the forward plug (the one in the anchor locker) out all of the time and the other two in, except when trailering (in case it rains).

We're talking about what became the 130 Sport in 2001. In the years just prior to that, it was called the "13 Sport", but the hull is unchanged for 2001 through current. So technically, this thread belongs in Post classics.

If you leave the under seat plug out when moored and the boat has no one on it the boat will drain. It's amazing what gravity can do.

When we have a lot of water in the boat for whatever reason and find ourselves swimming at anchor we have our draining trick. We level the boat with just me on board and the water runs out. Then my wife covers the thru-hull from below and I put the plug back in. We can actually get most of it out when we are both on board by plugging that hole really fast. Sure beats maintaining bilge pump wiring.

Correct me if I'm wrong but my impression is, the rear deck on 130 has a downward slope from the stern to a spot just about in line with the front plane of the rear seat.

Isn't this why there is a need for the mid ship through-hull drain & plug?

aubv; you are correct, of course.

From the owner's manual:

"The deck drain provides self-bailing capabilities while
the boat is static in the water and no passengers on
board. This feature prevents the accumulation of water
in the cockpit. The drain must be in place when

I have now stolen the fire extinquisher mounting idea. I have also finally thrown a page up with some pictures. Scroll down to near the bottom.

My 2002 130 sport doesn't have a vertical brace under the main thwart seat, and it doesn't really seem to sag a lot. I mounted my fire extinguisher directly under the port side of the main seat, just ahead of the battery box. Completely out of the way, but instantly available.
I experimented with the center drain last weekend, and with one or two people in the boat, water indeed comes in, not out. At rest with nobody aboard, it does drain the whole boat.
