It's been a long time but...
...I spent summers on a lagoon in Waretown in the early 90's, Pebble Beach I think the development was called, and sailed an O'Day 222 up and down that part of the bay, over to the back of Island Beach State Park, etc. The 222 has a 20" fixed keel and a centerboard that drew 4'. Also, the tiller was the kick-up type which drew somewhat less than 4'. Unless you stayed in the main channel where all the thousands of go-fast powerboats were, there were many times that the tiller kicked up. One of the reasons I'm on the Cheaspeake now is that I wanted to go bigger and just couldn't see it being any fun on the Barnegat. On the other hand, if it hasn't changed, go check out the numerous sailboats at Mariner's Marina by the Barnegat City (on the mainland below Waretown) town dock. The people there can probably give you their thoughts. Happy Sailing!
