Pirate ship modification costs (Skulls and Shackles question)

[Sensten]

Are the costs for ship modifications presented in the player's guide reduced if the player makes them, as they are with crafting magical items? Or is the cost the same regardless of whether you do it yourself or get it done at Rickety Squibbs?

[Sam Sturkie]

In our game we ran with 50% cost if the party does it them selves. Though finding a suitable location for an extended period of time can be tough
