I've been using my iPad a lot in my pilothouse. It has been really nice in many ways. It's particularly nice to use it as a screen
with alternate content - like weather
continuously being updated. I've been on the Chesapeake since September and it's nice to watch the weather radar
coming from various sites overlaid on maps - those Chesapeake storms can whip up so fast. Add to that some wind
display pages and it provides a lot of utility.
I've had almost no issues with sunlight readability but mainly because my helm
is so protected. I can understand why some people might not like it out-in-the-open because of sunlight and spray issues.
times, the device is wonderful. I've especially gotten into Flipboard to catch up on personal/social media and areas of interest. It turns some blogs/websites into a magazine and allows you to flip through to find things of interest to dig deeper. I use it almost every day.
I think the uses for an iPad onboard are just starting to appear. It can surely be a backup chartplotter
but I have a feeling it's going to fit into a lot of other accessory cruising areas (semi-navigational) much better for me for a while.
