Using a wireless client as a bridge has some caveats because the 802.11 standard isn't designed for it. The full details are here, but as a practical matter you basically have two options:
1: Configure the Groove for station-pseudobridge, and connect it directly to your laptop only, no switch or other devices involved. You'll have to do this when connecting to a non-Mikrotik AP. You'll also have to do this when connecting to a Mikrotik AP that has not been configured to enable the client bridging protocol extension.
2: Configure the Groove for station-bridge, and connect it to the switch as intended. This only works when connecting to an appropriate configured Mikrotik AP.
The Wireless Scanner tool (Scanner button on WiFi Interfaces in Winbox, or command) on the Groove can show you the remote AP capabilities; the details for any it finds will indicate whether it is a Mikrotik device and has the bridge extension enabled. Of course this would only be useful when you're in range of the buoy, so probably not much help at the moment.
If it's a hard requirement that you connect through the switch, and you only need IP connectivity, then another option is to ditch bridging entirely. Instead configure the Groove with separate IP networks on each interface and have it function as a router. You'd need to add a static route on the laptop (and any other relevant devices) for the buoy's network, using the Groove IP as the gateway.
Edit: I mean router + NAT in this scenario, as if the buoy is Internet. Plain router is only technically feasible if a default route on the buoy is already set up.
I believe station-pseudo ridge mode is limited to l2 bridging to a single client. So having a switch in between probably won’t work. I think best solution is station bridge mode with nv2 between two grooves to have a seamless extremely low latency connection.
