Hi,I am curently looking to buy a Cat 30 with a wing keel, to sail in Florida &Bahamas waters in the winter,and Georgian bay in the summers. Do I need a tall rig or is standard rig OK .Question # 2, I looked at an 1988 and the owner told me he had to have the hull shaved & reglassed because of severe blistering. Was this an isolated insident or are there specific years I should avoid. Any feed back on these questions would be greatly appreciated Terry
