Replying to Water ramps and skis breaking?

I have some ninthwards that are in pretty good condition. bases are really good and they're overall in pretty nice condition except the topsheets. they also have some good condition scratch bindings.

i was wondering if i should take them to water ramps. i was planning on using them as urban skis for the 09/10 season. will using them on water ramps (6 days) be really bad for the ski? like make them waterlogged or break them? or when i'm done will they still be all good?

thanks
