I bought the Boat Vent II with support pole at the same time I bought a new cover for my boat. Unfortunately, the vent comes with no instructions on its use. iboat.com customer service could offer no assistance on how to install it. (very disappointing they don't understand the products they sell.) Looking at Taylor Made's web site, it looks like I'm supposed to cut a hole in my brand new cover. There's no real instructions on the site on how to do this (the video is pretty useless). I assume there would be some reinforcement installed to avoid creating tear points where the hole has been cut, but none was provided with the vent. In summary, the Boat Vent II sits on the shelf, because I'm not cutting a hole in my brand new $500 cover without any assurance that I'm not destroying it.
