OK this is for hard-boiled modelers but there is yet another carrack model: the Conquistador, made by Heller, scale 1/90. Supposed to be one of Cortez`ships of around 1519 and Heller claims that the model is based on the documents "Consolate del Mar" in Barcelona.
While that may be true it is more obvious that it is actually based on the "shoe-shape"-Santa Maria. What you get is a complete Santa Maria in 1/75 plus LOTS of parts for altering almost the entire ship. The whole hull sides get add-ons to make it higher, a massive, two-level front castle is added and an equally big stern structure with side-balconies and all is topped by several wooden supports for big awnings.
While Heller has made a big effort to alter the Santa maria appearance, there are still some issues that make me shake my head. Okay, you get higher hull sides, but the main deck stays the same, so you end up with a "railing" height of around 3 meters! Everything from the bottom to the shelter deck is unchanged Santa Maria stuff and therefore 1/75 in scale, everything upwards from there is 1/90 - you can actually see that the ladders get finer and smaller as you climb upwards. Some of the masts need more length so you are supposed to add a plastic rod to the existing mast. How is that supposed to provide any stability?? A strange hybrid ship kit indeed. The base kit is one of Hellers first efforts and is a bit heavy and rough in the details while the add-on-parts are much finer in wood grain and detail.
I have that thing and one day I might start by building a completey new, raised main deck, raise the waterline, replace all those stringers on the outside of the hull, discard the (far too big) guns, build new ladders etc. . The strange thing is that the model does indeed look great and I´m pretty sure with a lot of work could be made into something that resembles a scale model.
There is even a big wooden kit of the very same ship, called a "Carracca Atlantica". Even the colours are identical to the Heller instructions. That might be something of a prove that the design is not a fictional Heller "escapade", but, unfortunately, there are many occasions where the (European) manufacturers have based an expensive wooden kit on an existing plastic kit with no further research. Nevertheless, here is a link to a pic.:

This is the wooden one, the Heller kit is OOP but it pops up on eBay every now and then. At least the wooden kit seems to have the main deck on the correct level as you can see on the guns which are in a higher position than on the Heller ship. And the Heller one has only 4 guns due to the Santa Maria Origin, otherwise both kits look almost identical. The Heller boxart looks similar to the Zvezda San Gabriel reissue, but remember, it is a different kit.
