You can add a cooler to keep your drinks cold. KULA make the perfect round coolers that attach to the Bote SUPs, and they even double up as a seat. 

You can add coffee cups or drink bottles. Some SUPs come with magnets to hold cups, and some have attachments where you can attach a cup holder to the SUP.
