I want to introduce myself to the forum. I am a new sailor (power boater for 30+ years) and purchased my first sailboat a Hunter 240. I put her in the water this weekend and brought her to her new home in a marina but have not sailed her yet. Hoping to this week weather permitting. I came across an article that stated you should never sail with a swing keel partly lowered because it is too dangerous. I looked for information on this and find it conflicting. Where I live in Florida outside of the channel most of the Lagoon is under 5 feet deep so being able to raise it while sailing seems to advantageous. The previous owner stated he use to lower it about half way down most of the time when sailing. Any other 240 owners have some input and how raising it and lowering it will change the performance of sailing. Thanks.
