Yes, that is a bit different. If I remember correctly, the well on the 336 (I don't have a picture and I'm not on the boat) has that shelf, but definitely not the extended area to use as a mounting base. I've seen one of those low profile Lewmar windlasses installed on that shelf in a 336, and they had to cut a circular hole in the locker lid to let the top of the gypsy protrude. It didn't look bad actually, sort of like it was a custom install. Ours also has a flat bottom with an installed drain, rather than that deeper dropoff toward the bow. Also, our water fill is outside the locker on the starboard toerail just aft of the bow roller assembly. I know there are a lot of other subtle differences as well, some of which were inprovements based on things they decided weren't quite right on the 336, and others that were definitely cost cutting to continue to meet a price point during a time of moderate inflation. I'd think I'd like to have an arch, but I really don't care for those support rods at the lower mast. Ducking under the lower shroud as you go forward isn't that onerous, and I use our forward handrails to tie the dingy down on the bow.
