I learned the hard way that a short inlet requires netural tide
Tide is related to the depth of the water, and current is related to velocity of water over the bottom. So the best time to run an inlet is slack or no current. This time may not be the same as the highest or lowest of tides, although logically it might seem to be. It depends on many dynamic factors. Thus it is always good to check the tide and current tables. Look carefully at an inlet--often from inside it may look calmer than it actually is.
Running into an inlet, especially on a ebb tide (water coming out) can be very dangerous. Although our C Dories are very "sea worthy", one has to be cautious. There is a reason that the Coast Guard motor life boats have no real cockpit. They are basically made to survive a capsize. Although a capsize would be unusual, one does not need to tempt fate!
Foggy's comment is very important. Many boats, will have two or more bilge pumps. The way the C Dory sits at level rest, often the water will pool by the foreword end of the cockpit--and that is where the factory bilge pump was put on some boats. Others had the bilge pump placed all of the way aft, right by the drain plug, since that is where water pools when the boat is running at faster speeds, including on a plane.
