If tighter, it depowers the sail. Remember that 'port' and 'left' both have four letters, and that drinkable port is red, and so is the colour used to indicate a port rounding. There is no such thing as a 'rope' on a dinghy - they all have different names depending on what they do. A halyard pulls a sail up, a sheet controls a sail, a lanyard ties something on. The slowest point of sailing.
Asymmetric spinnakers are much simpler and more powerful.
A boat on starboard tack is sailing with the wind coming over the starboard side, i.e. the sails out to port. This tack has priority over port tack. The trapeze usually takes the form of a ring attached to a wire on the mast, and the crew wears a harness which hooks on to this ring. Trapeze boats are usually very powerful, hence the need for extra righting force. The slow but safe alternative is to turn the boat by tacking instead, which means going a long way round but increases the odds of staying up.
