I would cut an access hole and add a hatch. I had to do that for my forward bilge pump drain house. It was pinched when the deck was added. I was not able to access it from the speaker hole. So I cut a circular hole approximately where I thought the pinch was located and added a circular hatch.

I sent a message to Aaron asking what could be done. From our previous discussions the hose runs under the captain's chair. The chair is attached to a metal plate under the chair to distribute the load. I'm concerned that cutting into the deck near the chair might create some issues and weaken the deck near the chair. There is a hole for the galley drain and if I remove the galley I might be able to reach some of the hose and try to dislodge it from the pinch point.
I did check the drainage after my testing and much to my surprise the deck drain did empty. It probably took 1/2 hour, but this is the first time it's ever drained. I'll be happy if it continues to drain regardless of how long it takes as long as it drains and I don't have to put up with stinky messy water and mildew in the center storage deck drain trough.

If it is finally draining, albeit slowly, could it be some kind of clog that maybe you broke up a little by forcing water through it with the hose? I think I'd try capping the sink drain, or maybe even stuffing a hose in it and forcing water down the sink drain and the storage drain at the same time. If it is some kind of clog, maybe you can break it up with the pressure from 2 hoses.

Assuming it’s in your driveway, maybe drain-o or similar?
Not familiar with the SC layout, but can you remove the captains chair for access? Speakers are another easy entry. Anything you can remove anywhere near its routing, I’d be pulling out.

A cleaner solution might be to use an air compressor, connected to the thru hull. If the air pours out one opening, cover that opening with gorilla tape. Move onto the next opening and do the same thing. The air might also dislodge whatever is in there. You can do this alone and not wait for a helper.

I was overconfident. Next trip went back to previous condition..center storage deck drain doesn't drain, and galley sink drain takes about 1/2 to 1 hour to drain. My guess is putting water under pressure through the drain hose temporarily opened it up, but it collapsed again and now won't drain. I asked Aaron in an email what options were available and no answer.
My guess is there isn't anything clogging it (nothing unusual came out when it started to drain). You can see that the drain hose from the center storage drain to where it goes under the captains chair appears pinched. Aaron saved me from removing the chair since he doesn't know if I could ever line up the plate it screws into after removal. Guess I'll just have to live with it unless I really get frustrated and cut the deck behind the chair mount. My concern in doing that is weakening the deck right around where it gets stress regularly in rough water.

I may have some hint here since I just yesterday had the sink drain in my 275 DC all apart to fix what turned out to be a manufacturing defect. The boat probably never drained from the sink from what I can tell, because once I dug into it I could see that there was a severe kink in the drain line, which is 3/4" black rubber automotive heater hose. The kink was in between the sink and a T connection near the through hull fitting. The upper end of that T went to the center locker drain, and the starboard side of the T went about 6 more inches until it was connected to the through hull. In effect, my sink drain snaked from starboard to port and then did a sharp bend back to starboard in order to connect to the T, and that is what got kinked up. Since the prior owner never really used the boat he may not have cared that the sink didn't drain, or maybe the kink happened once the boat got good and hot with sun on the cover to heat it all up and the kink just formed where there was a bending tension on the hose. If the routing of your drain is using similar hose and is bent tightly somewhere, you may also have a bad kink in it. Getting access to it will be the trick however. In my case the whole thing was under the galley console and I had to remove the refidgerator and an access hole cover to get to it all. I fixed it by replacing the sink drain hose entirely and adding a couple of 90 degree elbows in the path right out of the T to route the hose more in-line with the way it needed to go. Hopefully a one and done fix! Attached photo shows the original sink drain hose held in the approximate position it was installed in the boat. The kink is clearly seen and that end was connected to the T on the port side of the T, the storage drain flows into the top of the T, and the starboard side of the T goes to the through hull and overboard.

It won't be soon but, I'll take a better look when time allows. It would be nice to get it fixed or at least working better.v

yes, same with me, not soon, but on the list. Doing auto pilot & radar in about 2 weeks.

Hey Richard, I know are laid up now for a while but I was wondering if you ever figured out your drain issue. My bet is on a kinked hose just like I had. If you have a refrigerator in your galley package and if it's like my 275, it comes out with 4 screws and reveals a small access hatch under the galley. That hatch gave me access to see my kinked galley drain hose at the T which acted a lot like your drain issues...in my case a very slow to no draining galley sink, but adding a pressure hose to the ski locker drain made a lot of water flow out of the same thru hull that the sink was connected through. I would bet you a pain pill that one of your hoses has a severe bend and has kinked.

Pinched line. I drilled and will put a 4" round access in the storage compartment. As the one picture shows you can see the pinched drain line. The drain should have been secured, as the electrical wires are. There is no easy fix for this.

Same black automotive heater hose that Sailfish used in my boat. It is soft especially when warm, and routing correctly is important to prevent kinks and pinch offs. I consider this a manufacturing defect...a bit of care in the workmanship would have prevented an annoying problem! Thanks for the update.
