Saving for them isn't very hard, there isn't much to spend gold on besides ships really.

The frigate was the last on my list not because it was the most expensive, but because I prefer the sloop and the galleon over it.

Sailing a lot against high level ships and getting Royal Treasures is a great way to make money... For me War Lords are the best loot to difficulty ratio. Juggernaughts are still tough and I don't notice a huge difference in loot.
