I recently purchased a 1989 Ericson 38-200 and have a question about the waste and water tank location. The waste tank is located in the forward part of the lazarette next to the bulkhead. The water tank is located under the lazarette floor, which can be removed by removing the screws that hold it down. The hot water heater is located on the lazarette floor. To access the water tank it would be necessary to remove the hot water heater. (see the attached photos). Is this the way it came from the builder or has a previous owner done some re-engineering?
