I am sorry that I cannot answer your question but I thought I'd offer this comment.
Last summer I bought a 2008 Sea Ray 240 SunDeck for use on the lake.
Last week I bought a 2012 Sea Ray 220 SunDeck...for use in Florida.
Last night I commented to wifey how I feel 22' is adequate for the Gulf of Mexico, Gulf Intracoastal Waterway and Tampa Bay BUT the 24' boat is needed on Lake Wiini.
