First the good news: It could be done. You would need to plug in a transceiver that would respond to the remote as well as put the lights on X10 switches. I have no idea if the range would be good enough, however.
Now the bad news: I'm not sure how weather resistant the X10 components are. I'd hesitate to use them for outdoor use unless you had weatherproof covers for the switches and the transceiver module.
I think they may make a non X10 product for this purpose but you would have to check a boating supply store for it.
