As requested by member Canoyar.
These are taken from my 91 model 210 Walkaround.
A little history:
In 91, the cabin model Aquas were labeled as "Walkarounds". Two models, the 210 and the 230. Both had bolt on anchor pulpits. In the 92 model year, it appears Genmar renamed them "Explorers" and that name stayed with them the reminder of their lives.
In 94, both the 210 and the 230 were built with the "Euro Transom" and relabeled as the 225 and 245/250.
The Explorer and the Osprey share the same hull with different caps.
Do not confuse the EX 250 with the Delta Conic hull with the 245/250 Explorers. Manufactured in the mid 90s, it is an entirely different hull than any other Aquasport and is not the model we are discussing.
All model Explorers share the same dimensions from the bow though the cockpit. Their overall length (LOA) changes as does their weight and options so...
The cabin is about 100" wide at its entry. A V birth, it narrows down to about 20" at its "nose". It's about 84" in length down the center. "Sleepable" space is roughly 75" at its widest and about 60" in length. Usually fitted with 3 cushions, one on each side with a middle cushion with a plywood base that supports it over the "step down" area of the cabin. There is often a small "port-a-potti located in this step down area.
The cockpit is roughly 70" long by 84" wide. This is inside of hull side to side and from the back of the "ice cooler"/live well to the transom. The 225 with the Euro hull will lose several inches in length due to its design.
I've slept both in the cabin berth as well as up on deck in the cockpit area.
Having owned 4 Aquas, I feel that the EX/Ospreys of the Genmar era were the most comfortable riding hulls. I'm a big fan of CCPs having owned both at the same time. Both can be wet with the right sea conditions and the 225 is a great all round family hull.
Good luck with the hunt.
