Hello,Been out of sailing a while and just got a 1973 Oday 22 still in the water. overall pretty good shape. This question may have been posted before so please excuse if it has. I am converting a power boat trailer to put the Oday on. It will have a keel board so what may the specs be for the bunks starting with height form keel board? It does not have to be exact just have to get it a few miles where I can than set it correct. Thanks for any response. Russ
