I've never had water over the sides or the stern. I get less spray over in the bow and on the windshield than a Supra Launch 21 I've ridden in many times. I've never had water over the bow in storms or normal driving but I have had some over when I've not paid attention going by a cruiser wake. I've driven in a Tige 21V and know it takes bow water in more easily than my 215. That's my personal knowledge.
The VLX looks higher in the water than the 215 but I don't have any personal knowledge of which is better for shipping water. They're both good boats. I'd choose the Sanger for the handling but when you test drive them you'll find which you like better. Get the Bennett plate when you order your new V215.
