Handling appears to be similar to other boats that size, no apparent quirks. Heels ok, the shallow draft is a plus, don't forget there is some 2500 pounds of lead in that winged keel and you have a 10 foot beam. I have a 155% genny and on a broad reach in 12kt wind there was a slight heel. I had the boat surveyed by a competent surveyor and the only problems were a blister on the rudder and the cutlass bearing had to be replaced. Did it myself over the winter, got tips and ideas on the O'Day e-mail list which you can sign onto at this web site under resources - e-mail list, great group of people who are always willing to help. Had some nicks on the gelcoat which I sanded and epoxied for now and the chainplate connections were all good. Have the boat surveyed, it is well worth the money. Post on the e-mail list for a surveyor in your area. Also if you don't mind me asking how much is the boat and what comes with it. I think an O'Day 302 starts around $33000.Check out Oday sailboats Owners Web for Oday Sailboats and O'Day Daysailers

Hope I was of some help
