colvosview":2twv3wp7 said:I have used one for several years. It is not maintenance free - I have to get in the water every year and pull all the mussels off, or it gets very heavy. Where I am, I can catch a low tide and do it with waders. Also, I've had the PVC framework come apart a couple of times. I think the constant movement is not typical for PVC joints, so the glue doesn't always hold so well. On the whole I am happy to have it keep my boat high and dry.
