Searching for a theme that supports boats tournaments management

I need an existing Wordpress theme on the market, that let me manage boats races, where users can log in, and register (with money) to existing race, register their own boat, and team.

Is there any such theme, or even a theme about other subject, but that as all or some of this functionality?

Sounds far too niche to be available on a stock marketplace plus envato do not allow items related to gambling
