My day job involves overseas circuit and device design/manufacture. From the Alibaba listing, the maker mentions an inhouse design staff and that they own the IP. I suggest you contact the maker and suggest a 5-10 Hz update rate to best address the marine market. You may get samples by mentioning the specific size of the OpenPlotter user market and your open source efforts on this forum. The update rate could be a very minor change.
