Responses are good
The responses are good but if you are new to sailing, I would suggest staying out of the heavy wind sailing until you are more experienced. As for the keel, I found that in the years of selling and sailing those boats, I found the H 23 wng keel is very well balanced to the displacement of the boat. When looking at the hull, may I suggest that you do look at the wings as they are not bent, broken and so forth as it will deter the performance. If rusty, clean the keel, use a wire brush to get the oxidation off, fill in any gaps with a two part epoxy sealer, spray zinc chromate on any of the cast iron to prevent rust and then repaint before putting back into the water. Also check the keel to boat joint and if cracked, simply remove enough portion and put in epoxy sealer(this does not mean water is coming into the boat)Good luck and happy sailingCrazy dave condon
