Having won five of the six races in Greenock and Milford Haven, Harvey has a resounding 39 point lead over second-placed Tim Batte with only the meeting in Torquay to go.
A clean sweep of victories in Scotland was followed by consecutive wins on Welsh waters before being knocked off top spot for the first time this year in the final race of the weekend by Batte.
“I’ve had a cracking season so far across the British and European Championships and have won a possible eight out of nine races so I feel like I'm coming into the final round strong and with a positive attitude,” the 27-year-old explained.
“Currently in the British Championship, I've got a 39 point lead that does help take the pressure off slightly, however anything can happen after all it's racing. Mechanical issues and the likes of it.”
While Harvey may not be taking anything for granted, his great form has lifted him to within touching distance of the title and he can now secure the series success on familiar water.
“I'm really looking forward to racing in Torquay next weekend, it's a perfect venue for jet ski riding and racing,” Harvey added.
“I spend a lot of time there and it's where I do all my Aquax training. I've been coming down here and getting out on the water since I was a young boy so for me it's really home from home.
“The bay itself is a haven for water sports and I have no doubt in my mind that the racing is going to be superb. The conditions are usually a little tricky especially when the wind is blowing easterly. If that's the case we can expect some big swells and some quality viewing for the spectators.”
