I am trying to decide on whether to opt for the rear cockpit glass that started as an option in 2015 (if memory serves me correctly). I can see the advantages in bad weather or stormy days at sea, plus not having to deal with isinglass. Also I hear it cuts down on engine noise under cruise. On the other hand I like the open feel without it, especially on a day out with friends and family. I am coming from smaller PCs and it?s nice to be able to be at the helm while still feeling connected with the aft lounge. The door seems to splits the aft in half. I am also wondering if the isinglass provides enough insulation when using the 30k BTU A/C in either hot or cold weather. If anybody who has experience either way could share their experience it would be greatly appreciated. I am finding this to be a tough decision! Thank you!
