Opacmare hydraulic davit system. 24v 250kg capacity fully extended. This was NEVER USED. It was removed from a brand new yacht in 2007 and put into storage. Extended dimensions of the boom are 8ft long and around 7 ft high. It swings 90 degrees to one side. I have a video of its operation available to anyone who is interested. I can assist with loading but buyer is responsible for shipping. Any questions feel free to ask!
