hi, i've been toying with the idea of adding a hard top to my boat ('87 tiara 2700). i am thinking i will probably wait until the current canvas needs to be replaced and then replace it with the hard top. i'm wondering what the ballpark cost would be? i know it's difficult because it depends on a lot of stuff, but i am thinking the 27 albermarle top on your website is what i'd want...and i'm just trying to gauge the price range i'd be looking at. thanks...
