I bought a 76 E25 this year and have a few questions. Does any one have pictures or sketches of the starboard settee berth sliding out to a double? I need to add this feature. Second, does the gooseneck slide up and down in the luff groove on the mast? I live a days drive from the boat and can't check this. I want to add a foot or so to the hoist of the main by dropping the gooseneck.
