Hi; I bought an old Reinell 2200 and just took it out on a lake last weekend. I was looking for some advice about the following: 1. The old smoked lexan/plexiglass has all kinds of cracks. Does anyone have a good solution for rebuilding the cabin doors and top hatch? 2. I lost the original rudder and as I remember, it wasn't much more than a 1x10x48" piece of board. I made a new one a little bigger, but I was wondering if other owners had made better rudders, and what size/ shape to do so. 3. Internet sources I have seen say this thing has a displacement of 5800 pounds, is that right? I was thinking 3800# or less, does displacement mean just the weight of the thing unloaded, or the volume, or what? Thanks for any help, brand new sailor here.
