I am a novice sailor who got chased away from my motorcycle by an overprotective wife. Traded my motorcycle dollars for a neglected 74 O'Day 20 (centerboard) that is a fun project but still months away from getting wet. While looking for a suitable outboard, I bought a Suzuki DT4, with an 87 Catalina Capri 18 (shallow draft keel) attached to it. The Catalina is pristine and ready to sail. One boat stays, one boat goes to e-bay or craigslist. I will be doing (1)lake sailing, (2)solo often, (3)considering a marina slip for easy access (4) have suitable trailers for each. Not in a hurry.Which is the keeper and which is the throwback?
