$ 450 is pretty steep
Your shroud can be bought directly from Catalina and it doesn't take that long to mount and tune the boat. I had no background in rigging and I took my 380 completely apart in Flordia, shipped it to California and recommissioned and tuned it myself in a day!!! I learned a lot in doing so. One shroud would be pretty easy AND you would be learning about your boat. You can get all the info you need from Catalina OR right here on this web site (and feel good about doing it yourself).............. Good luck, Gary
