"I can't see myself ever trying to catch a wave" ==> follow "obijhon" advice
And if transporting and storing a 12'6"+ hard board is too much of a hassle, a good cruising 12'6+ inflatable board by a reputable brand (avoid the "supermarket" ones!), will be night and day compared to your current board.
Have a look at
www.supboardguide.com/best-inflatable-paddle-board-reviews/(this is just an example, the first google hit for "best inflatable SUP chop", there are many others)
Do not pay attention to just the rankings of trusting these reviews for designing a "winner", but look at the details on how the boards
handle chop, the weights that can vary a lot, etc... not inflatable boards are the same.
