Good morning, guys!
The very first vessel of the Peruvian Navy (which predates to the formal independent nation) was the schooner Sacramento, an armed royal (Spanish) mail ship with regular service between Panama and Callao. She was captured by the pilot and the rest of the crew off- Paita in 1821. Shown here with the first pattern of the Peruvian flag. Cheers.
NB: Despite having a model in the Naval Museum at Callao, there are no specs other than the displacement and the number and weight of the anchors. I followed the description of the sail rig given by the captors (with the exception of the square sail in the fore mast, which is lacking in all the representations of a Spanish schooner of late XVIII and early XIX, only fore and aft sails; in fact, the only schooner with a square sail and not topsails was an american revenue cutter of the first decade of the XIX century
), but for the hull form and mast colocation, I followed closelly the lines of a Spanish schooner of early XIX century. My appologies for the expected inaccuracies.
