Sailed Both
Our Sailing Club charters out many Hunters, including the 30's and 310's. The newer Hunters are lighter and must be reefed earlier in order to preserve stability. Additionally, they have no backstay (if you are inclined to ever add a backstay adjuster). In addition to being lighter, I did not like the 310, due to:1. Lack of a real navigation table2. Battery switch at the back of the aft stateroom (crawl over the bed to turn the battery on).Also, you may want to get ahold of the Practical Sailor test reports. I saw a caption in their advertisment which stated "Rigging Problems with the Hunter 310"We ended up purchasing a used 1991 Hunter 28, which is a slightly smaller version of the 30. My personal preference is stability...mainly because we sail on San Francisco Bay.If you can "test drive" both of them-do it.Gary Scheiers/v "Serenisea"
