Okay, here we go... I'm starting with the three-deckers and the two-decker 80s. (As the last two 80s were grown from Ildefonso 74's by splicing in a 10' plug in the QD area, I have elected to "promote" that entire family tree despite Ildefonso being some of the weakest-armed Spanish 74's.)

Note that unlike British/French practice, Spanish measures at "lowest planked deck"--the length of this deck is called "eslora", we're using a length here that includes the stem and stern overhangs beyond that. Typically the Spanish approach to "adding a deck" appears to have been just building up the bulwarks and waist to "bridge" the existing QD and forecastle into a spar-deck. Guns listed here are design/"war load;" in practice the fleet usually had to make do with whatever smaller guns they could get.

THREE-DECKERS
We need a larger sculpt. Purisima Concepcion and Meregildos, despite being two different "design systems," are close enough in size and shape I would be comfortable using either as the other. "These two de facto prototypes (PC/SJ) were followed by eight improved three-deckers (Meregildos) designed to the same general pattern, but modified by Landa...") The problem is the older ships...

Landa/Retamosa school - Retamosa's Neptuno 80 was a simple stretch of Montanes, a minor tuneup of Landa's Ildefonso 74 so I'm treating the ancestral 74's as under this heading

Preliminary thought: If I had the chance to do an Ildefonso sculpt, I would slipstream the two 80's onto it and juice their stats accordingly. We have potential for one British and two French reflag packs.

Still working on the 74's, will post them when ready, then the small SOL's, then the frigates and smaller--frigates get nasty, as there were several cases of inter-related designs differing in longer or shorter upperworks.
