After we learn to sail in only 3 days, we'll probably need repair parts for the Sunfish :) I like using Yankee Boating Center, they answer the phone and also have a nice online store at sunfish sailboats.com. I have also ordered from Laser Performance and have a local Sunfish dealer, Key Sailing, who keeps some parts in stock. Other parts we have found on Craigslist and Ebay, but do some homework before paying too much. Two other good resources are the yahoo Sunfish Sailor group and Sunfish Forum. I have found parts there and also helpful advice to tackle most repairs or upgrades. Those two groups also have Files, Links and Photos, so budget some time when you go to visit.
