The weight is almost the same in fact the Getaway seems to weigh slightly more (but it's only 16ft and the 570 is an 18'). I've seen a 570 with a front tramp and it was massive! But still for me I'd rather not have the tramp (or have one that can be removed quickly when not in use) as it hinders the view of your leeward hull.
Best regards!
