The Marine Casualty Investigation Board has recommended that jet skis should be licensed and those using them should have to undergo mandatory training.
The recommendations are made in its report into the death of a jetskier on Lough Beltra, Co Mayo, in 2006.
The Coast Guard, in its report for last year, says that there was a 10% increase in jet ski accidents.
Overall, it had to deal with 154 incidents requiring emergency rescue help, most of which were caused by those involved in marine leisure activities.
The use of jet skis has been the source of controversy, with objections to their noise, speed and perceived dangers.
Reporting on the death of Alan Joyce from Castlebar on Lough Beltra, the Marine Casualty Investigation Board says he was with a companion, trying out a recently-bought jet ski which overturned returning to shore, throwing both men in the water.
They had ignored advice to wear lifejackets, were considered to be poor swimmers and had little or no training in using jet skis.
Because of the increase in jet ski accidents, it has recommended that the Marine Survey Office should explore the introduction of mandatory training for users, that all jet skis should be registered and anyone operating a jet ski should be licensed and complete a training course.
