Funnel in starboard berth
The funnel you are looking at is for the drain tube on the movable galley sink. The 22 had a galley box that slides aft under the cockpit. The sink has a drain tube that, when you slid the galley out, dropped into the funnel and drained through a Y valve connected to the cockpit drain and out the bottom. Most, like myself, got rid of the galley so the funnel use isn't obvious anymore. Bye the way, make sure this funnel isn't connected to the drains if you're not going to use it. My bottom got fouled one time and the hole in the bottom for the cockpit drains got plugged. The cockpit filled up with water during a torrential rain and backed up through this funnel and into the cabin because the funnel is lower than the cockpit floor. You can see the drain connections by removing the step cover just inside the hatchway.
