RE: Severne Glide weight
Unfortunately, I don't have the weight of the Glide as the USDOT impounded my truck and trailer on Friday nite, Saturday was spent getting the truck back and up to Lakes Bay (NJ).
Sunday was a very rainy and cold day, so you'll have to wait a couple of more days until I get to Worthington and can weigh the sail.
As far as the masts, I don't have a mast testing machine (yet), so I don't know for sure if the 460 Itallica masts are all the same, but I will check my Lightstick 460 againat the Redline 460 and see if they are at least similar.
Hope this helps,
