He says the boat owner made death threats.
The man from Torquay, who asked to remain anonymous, said the incident happened when he and a friend were using their skis to splash each other in Brixham harbour.
They say a boat owner objected to what they were doing and shouted and swore at them, so they left the area and the skier returned to Torquay Marina.
But as a result of a complaint, the man has lost the use of his ski storage pod at Torquay.
The jet-skier says he was called to a meeting with Torbay Harbour officials where he was shown video footage of the incident at Brixham in March.
He said he apologised but was then told he was banned for a year from Torbay waters for dangerous driving.
He believes no action was taken against the boat owner, who the jet-skiers say was abusive and threatened to kill them.
Details of the incident emerged at a meeting of Torbay Council’s harbour committee.
Councillors were told the ban meant the skier avoided being prosecuted under harbour by-laws.
The man said he accepted the splashing incident was not acceptable, but had learned his lesson.
He pointed out he and other experienced jet-skiers had volunteered to assist the authorities with emergencies at sea.
He had towed a stranded yacht back to harbour and on one occasion rescued a swimmer who had got into difficulties.
The jet-skier said: “It has had a big effect on my life. I feel like they are banning me to make a point to every other jet-skier.”
Another Torquay-based jet-skier said: “I believe he has been made an example of.”
Councillors were told the voluntary ban meant the skier avoided a criminal record and the action had sent “shockwaves” through the jet-ski community.
The jet-skier said he was unaware he had the option of prosecution instead of a ban, which he would have preferred if it meant he could return to the water sooner.
He said he was hoping to clarify the situation in a further meeting with harbour officials.
