Re: Boats in Berths.
Good comment Capt.<br />The Sea Pen was a plastic sheet with heavy rope netting attached/welded to inside. It is in the shape of a boats hull.<br />Around the top was an inflatable bladder, all the way around.<br />You drive in to it (it is sunk), auto inflate the bladder with air, and a pump removes all water between your hull and the "pen". It fits perfectly tightly around your hull and stern drive. You have percectly dry hull.<br />To leave, deflate the bladder, and pump puts water between hull and Pen.<br />Sea Pen attached one side to berth, outer side with bouys, so it settles whatever depth you wish below boat, so you just drive out.<br />Made of very heavt construction.<br />Still can't work on leg and force of water hold Pen against leg.<br />Anyone ever used one.<br />Cheers<br />Phillip
