If you spend most of your time cruising in calm waters, there are no special needs for your choice of frame other than remembering that the frame should ideally be a ‘wrap fit’ to minimise the amount of UV light that enters the eyes. Without a wrap fit, UV and visible light reflected from the water surface will always find a way in, even if you are seated at the helm inside the bridge.
As you are unlikely to be suffering from significant spray and sudden jolts, the leash and necklace of the Surge and Typhoon would be surplus to requirements, so the most suitable model for this kind of boating is the FLO. It’s a lightweight 8-base wrap frame which has the added bonus of being floatable. If they are accidentally knocked overboard, they will be simple to retrieve from the water.
For those that spend a good deal of their time indoors looking at digital navigation instruments, you may want to consider a non polarised lens or a lens which is ‘screen friendly’. See below for details of our Zeiss multilayer red lenses for the FLO. If you’re spending more time outside and on the deck and especially in bright and sunny locations, you’ll be more comfortable with a polarised lens with a VLT rate of around 10-12%. A blue mirror coating would also be well suited to blue ocean environments.
