I say is mostly a CD25D since it has an internal diesel ('Beake 13)... But the vessel is missing other CD25D features...
The aluminum 20 gallon (!) fuel tank is up under the v-berth, as it the water tank.
The large laz in the stern has the transom cutout in the cockpit bulkhead for an outboard, but the through-hull well for the lower unit never existed.
No kitchenette feature, just the tiny sink with the faucet w/the bicycle hand pump to move liquid from the tank to the sink. (Thats one of my next projects.)
Not really a CD25, but not quite a real bona fide 25D either. Poor hybrid child.
So - to the meat of my question/problem/issue- That fuel tank. Gah.
Original equipment as far as I can tell... Manufactured by JTR Enterprises in Gulfport FL. (right down the road?!)
It doesn't look like its ever been removed or really checked out. It was held in with long-ago broken metal strapping.

Anyway - was on my first really long trip - originally planned a trip from St Pete to the Keys, hopefully the Tortugas, but this became more of a shakedown cruise.
Got beat up pretty bad coming out of Tampa Bay - that Skyway bridge is a beast.
The diesel started running really rough. We pulled up in Manatee River and I checked the Racor Water/Fuel separator.
Diesel bug. Bad.
Ew. Over the course of the week, motoring down the West ICW the engine would run OK for about 3 hours before it started losing revs, 2 hours if it was choppy.
When that would happen, I'd pull the collector cup and dump out the water and diesel bug oatmeal... after 2 dumps, the filter was clogged.
I bought 4 NAPA Gold R12T filters... Every morning I dumped the oatmeal from end of the previous day and changed the filter.
After 3 days it was unbearable.
We had gotten the diesel level down to a workable level - I sourced some containers and we pumped all the fuel out that we could, but that still wasn't enough...
I put in about 8 gallons of fresh diesel, new filter... still had fouling issues.
Got back to Tampa (Skyway beating me to death again- Motoring into 15 kt wind, 4-6' waves and an outgoing tide. I was moving at about 1 kt.)
So... I decide to pull the tank... I knew the straps needed to be replaced anyway and to do that I needed to get the tank out.
Jeebus Pete! The condition of the tank.. One good hole, tons of pitting where the tank sat on wooden slats.
Local aluminum welder I contacted about repairing the tank and sent pics - told me I should just replace it.
Not exactly an item I can get on Amazon... And the odd shape of the space precludes most poly fuel cells of reasonable size.
