Hi folks. I bought my 2001 240 sundeck last year after living in my area for a few years, learning the canals, seeing the sizes of neighbors' boats, etc. Now the water is up over a foot, the highest in nearly 20 years, and the highest bridge out of my canal is within inches of the searay clearance. I've kept busy with my pontoon (obviously no hard top), which A. Sits a smidge lower and B. Is cheap should I misjudge or get waked into smashing a bridge. My new boat is not something I want to risk like that. Plus a wind change can seriously affect water levels, so while I can measure exactly on my trip out, I have no great way to tell on the way in. Sneaking out with 3 inches to spare is one thing, but a wind shift could result in a broken windshield. All summer I joked about filling a bladder with water to slip under and my family laughed at my crazy idea. Turns out such a product already exists, albeit with a different goal in mind. Has anyone used a ballast bladder for such a purpose? If so, since I won't be needing to maneuver much, how far past recommended capacity should I be able to push things, as I really just need the windshield to be lower? Anyone have an idea of what kind of weight would drop the boat an inch? Thanks everyone.
