What to expect in a sea trial
I usually try to do a series of things during a sea trial. I try to run the engine under load for at least 20 minutes to a half hour. I watch for signs of overheating, smoking or leaks. Most surveyors have miniature tachometers and temperature guages that they use to sort things out. If I am not familiar with the model, I will steer while motoring, and do a series of trials. Using a crab trap or other floating marker to help see how things go. I will approach the marker and than back down the engine to look at prop walk and braking. I will then back for a distance up and down wind at varying speeds to see how easily the boat backs. I will swerve with rudder to feel for play or slop under load. I will motor at cruising speeds and motor at idle. I will let the engine push the boat at idle and then watch the exhaust when I power up.
Under sail I try to test a boat in a range of conditions. It you go out on a windy day you can often get a sense of how the boat behaves in a breeze. You cna often find a lee to see how the boat behaves in lighter air. I try the boat on all points of sail and will also try each function on the boat. I raise the sails myself to get a sense of the friction in the sheeaves and adequacy of the winches. I also tack and jibe trying each of the positions on the boat. Since I single hand a lot, I also will typically singlehand a tack and jibe to see how well the boat is laid out for that purpose. Under sail I check each sail for shape and ease of changing lead. I operate the outhaul, reeflines and vang under load. I will try to knock the boat down by adjusting the sails for a beat and then bearing off sharply to a beam reach. I am trying to see is the boat will want to round up and if it can be controlled if it does. I will send someone to the bow and gently try that again.
While the boat is heeled (both tacks) I walk through the cabin and try each function down there. I flush the head (some boats can''t get intake water when heeled over on one tack). I look at the sinks and Icebox to see if they have taken in water when heeled. I lie in the bunks.
You should come off of the water with a basic understanding of the boat and its problems or merits.

Jeff
