Sorsogon City’s note – Based on my interest on history, I knew that Magallanes was a frontrunner in terms of Galleon construction during the Spanish occupation. Information can be read or obtained easily from the net. However, drilling it down to the detail of the Galleon construction is really challenging. But here are a couple of articles about Bagatao, one mentioned about the ship’s king.
Isle Bagatao – This island has its southern port a sand bank of considerable extent with 12 to 14 fathoms good holding ground, so that a vessel overtaken by a bad weather, and unable to make a port, may find some refuge here, taking care to observe that the said sandy bottom on nearing the mouth of the port is not good, being mingled with stones. 1
Bulan where the ship called Incaranation was cast away returning from New Spain in 1649. Sorfocon2, or Bagatao, where the king’s3 ships are built; and Albai, a large bay without the streight, where there is a high burning mountain4 seen at a great distance by the ships coming in from New Spain: in this mountain there are some springs of hot water.5

4Author’s note – obviously this is the Mayon volcano. A couple of decades forward, these hot springs are being used by the Tiwi Geothermal Plant.
