I have a !974 E-25 center board model & there is an icebox next to the sink on the starboard side. It is fairlly deep & I have not used it for any extended cruise. we keep a small icechest for drinks on the cabin floor under where the table mounts & it doesn't slide around much.
good luck

we recently purchased a 1974 E 25 shoaldraft & are gradually cleaning it up. The hatch cover needs to be replaced. I am looking for a source to purchase a new one or find out about materials & Ideas of anyone that has encountered this problem.
