Fast Galleons don't have the mast on the bowsprit. What they have is about five times the crew and much more firepower than the Golden Hind - even the merchant one has 38 guns of 9lb compared to the fewer, smaller guns of the Golden Hind. If you retexture one of the fluyts and remove its bowsprit mast, plus raise its crew from 60 to 85, that ought to do the job.
