Ship types
Im glad you posted that picture, the issue i have with the galleon is that its not at all a galleon, which have fore aft mizzen rigs it is in fact a: fully rigged 6th rate and you could call it a Frigate, though with noting to compare too it may or may not be particularly fast, also it bothers me that there is no jib sails or stay sails either these would greatly help when sailing into the wind on top of just bracing the yards. To prove my point, this is a full rigged 6th rate the HMS hyacinth which is a sloop i find to be most comparable to the so called "Galleon" http://collections.rmg.co.uk/mediaLib/541/media-541105/large.jpg
in comparison these are galleon, please note that every single non fictional vessel have fore and aft mizzen masts and are far larger. https://www.google.com/search?q=galleon&safe=off&rlz=1C1CHFX_enUS699US699&source=lnms&tbm=isch&sa=X&ved=0ahUKEwjq8LCKsOPZAhUQw1kKHUIkADgQ_AUICigB&biw=1920&bih=974
