PROBLEM TO BE SOLVED: To enable training of starting for boats at a unique timing regardless of action of a major timepiece. ;SOLUTION: An apparatus 10 for training of starting has a resetting part 13 to be operated by an operator of a boat 17 at the training of starting, a timepiece 14 to indicate the residual time to the operator up to the starting time when receiving a starting signal, an arithmetic part 12 which resets and starts an internal timer 18 when the resetting part 13 is operated while applying the starting signal to the timepiece 14 and a photodetecting section 11 to receive laser light 6, 7 and 8 when the boat 17 approaches a start line 1 on an approach water way. The arithmetic part 12 learns the time of receiving the laser light 6, 7 and 8 with the photodetecting part 11 referring the internal timer 18 and calculates the speed and acceleration of the boat 17 from the time obtained to forecast the arrival time at the start line 1. When a flying is forecast, an alarm generation part 16 is actuated to generate an alarm.;COPYRIGHT: (C)1997,JPO
