"So we have a lot of talks about him before the race so everyone knows about him, but it is also how to be safe on the water.
"We are expecting around 100 competitors on Saturday, which is more than last year, and it is looking like it will be a southeasterly, which means we will go from Maketu to Pilot Bay.
"That is the course that James and I did before he died, so it always ideal to go in the direction."
The race is much longer than most other ocean events for outriggers, surf skis and paddle boards, which Roozendaal says is because he wanted it to represent James and how he was always pushing hard.
"A lot of people prefer to do it as a team, as it is too hard, but we want people to try and be like James and go by yourself, and go longer and longer to go better and better.
"We make sure everyone has all the safety gear and letting them get experience of going out on the ocean and being in a safer environment.
"We have a good support crew from Kingfisher Boats and the Maketu Sea Rescue help us as well." The Champions Cup race has grown to be what Roozendaal says is the biggest and most popular of its type in the country.
"It seems to be the people's choice, the favourite, and we get a lot of support from the sponsors here who provide a lot of spot prizes.
"I just set up a race day and everyone turns up - its the people that make the race great."
The Champions Cup is expected to finish at Pilot Bay just after 1pm, with the first surf ski and outrigger canoes due about the same time in what will be a spectacular site for spectators.
There will be other craft in the water this weekend with paddle boards, open double outrigger canoes and double surf skis in action.
On Sunday, there is an intermediate standard race, the Maunganui Beach Relay Race, which is better suited to novice paddlers. Competitors will meet from 9am at the James Moore Memorial seat located up on the shore, looking out over the spot where James drowned to the left side of Leisure Island.
