The "classic" E-38 came out in about 1979 - it had a dinette to port and an entertainment center (a table with opposing seats) to starboard, plus a forward head. A variation on the 38, the 381, was also produced - it used the same hull and deck, but had port & starboard settees and a shorter rig. A few other permutations were also built: 38 short rig, 381 tall rig, settee plus dinette ... It could get pretty confusing!
The 38-200 Series came out in the mid 80's. It used the same hull, keel and rudder as the 38, but had a different deck and interior. It had an aft head and a large aft cabin. IIRC, the first few 38-200's had the engine under the galley, but on later boats the engine was moved aft under the companionway steps and the galley was modified. The 38-200 can be identified on the exterior by an additional opening port aft of the large fixed ports on each side.
The 38-200 with the "Euro-style" interior was popular when it was introduced and probably out-sold the classic 38, but there was some overlap when both models were offered.
