Flight from ZZZ to ZZZ1 in an overwater equipped aircraft with a co-pilot that hasn't completed overwater training. We were on a filed route that kept us close to the shoreline but had to deviate around area of heavy thunderstorms which got us farther off shore than authorized by our ops specs. I filed the flight [plan]; but didn't take into account that any deviation further offshore would exceed acceptable distance from the shoreline. Due to COVID-19 my co-pilot's overwater training had been cancelled and that fact I hadn't considered when I filed the flight plan. I will definitely review everyone's quals in the future and be sure the filed route complies with all regulations.
