Some boaters use electronic chart programs on their tablets and iPads to augment their navigation electronics, but in rough seas, it’s tough to hold these mobile devices while you run the boat. To make a tablet such as the Bak Seal 8 accessible, readable and secure, use a system like the RAM Mounts Universal 7- to 8-Inch Tablet Flat Surface Mount ($56.59, westmarine.com). A special frame grips the sides of the tablet while the adjustable, corrosion-resistant RAM Mount lets you fine-tune the viewing angle and place the touchscreen within easy reach. For larger tablets, use the RAM Mounts 10-Inch Tablet Flat Surface Mount ($58.76, westmarine.com). The RAM quick-release system lets you install or remove the tablet in seconds.
