Re: Full or Shoal Keel on New Oyster 575?
Some of the issue may also depend upon the how hard one ones to think/work at getting into a given marina, haul out etc. If one wants to go there at any time, one needs a draft that equals the lowest range. If one does not have an issue with thinking, planning etc, then one can go with a deeper draft! Then get the sailing benifits of the deeper draft boat.
If one wanted BOTH options, then one has to figure out how to have a CB or lifting daggerboard as some LARGER boat manufactures are offering. If the OP has this option, I personally would go that route, then deep draft, last after exhausting ALL OTHER options would be a shoal draft. Assuming one is going to have draft issues everywhere they go. I would have a hard time assuming EVERYWHERE there will be draft issues with the drafts mentioned.
