Interceptor style trim control would not be a bad idea and for the the pockets have to go and if i should need to install trim control on a boat without i would choose Interceptor style over trim tabs. What i believe that two hulls, one with and one without pockets will not happen as it would be a build nightmare for GW, so i expect that they probably just build the hull without pockets and install Interceptors what is ok. If they choose the SK Ride system it's most likely a commercial decision as some more experienced and more detailed in to boating buyers know the Seakeeper company and for who don't know Seakeeper nor Interceptors it don't really matter what brand is installed.
New boat prices rocketed to stellar prices and one reason is that builder include more and more expensive gadgets not everyone wants and needs, but thats probably because here boats are usually sold bare and new owner chooses what to install, including outboard brand.
Some boats come as a Package Deal with factory installed outboards, but in this case there is a substantial discount over buying bare boat and engines and have them rigged.
Other countries, other habits...
