Boat parts
1.Get VIP membership at beedles ship (200 points) for the maximum discount.
2.Buy/Obtain treasures and sell them at the treasure place on mercay island until you have 9999 rupies.
3.Change the date to 1 day ahead (this makes beedle's treasure stock and boat part stock respawn).
4.Find beedle, buy the parts you don't have.
5.Repeat process.
Notes:If you're lucky (like I was) you could get golden parts from him. If your luckier you may find a masked beedle you don't get a discount at his shop, yet go to him anyway he'll have rarer parts on him!
