Occasional use outdoors or at the beach doesn't compare to a marine  
environment. Heat, salt and humidity in a marine environment are much more  
difficult on electronics. I know of several computers that have crapped out  while 
being used onboard a sailboat. Marinized electronics have special coatings  
on boards and other electrical connections. Personally, I wouldn't rely on 
an  iPad.
My wife takes her Kindle to the beach all the time. She's had to replace  
hers twice (under warranty) after using it on the beach. Stick with  products 
that have been certified to withstand an occasional splash or at the  worst 
a complete submersion to a few feet.

I  believe you can get water resistant cases for the Ipad. Additionally, I
see  people using their Ereaders (specifically Kindles) outside and at the
beach  all the time. I think with reasonable care you will be fine.
Certainly,  people use their laptops on board all the time and I would
suspect an Ipad  would be much more water resistant than a laptop.
