Although I had some bad luck with it this summer in the form of a hard grounding and bent rudder post; overall I have been delighted. One factor that influenced my choice was the knowledge of how production boat builders cut cost and streamline production. One practice is to use the same size hardware and scantlings in 3 different boat sizes. The result is having the smallest boat being overbuilt and the largest cutting it a bit close. The Catalina has the same standing rigging, chainplates, and shrouds of boats over 35 feet and uses the same size keelbolts as their 42 footer. This saved my boat and butt last summer when I ran aground. While I did bend the rudder post, their was no damage to the hull/keel joint other than some cracking of the barrier coat.The 310 is on my short list of candidates for our next/last sailboat. Please let me know if you're on or near Lake Michigan and thinking about selling yours.
