With photoshop, this is about what the roofline would look like extended.
The structure needs to start at the hull. Down at the bottom. The lower stateroom bulkheads support the deck, supports the aft bulkhead supports the roof.....
Just build it make a reverse mold and it then will be exactly what you want I did this for a customer. It was made so that you can support the hard bottom raft also.
Right. I think Mario is going to do this right, and consider all of those points. I'm very interested to see how he does it. He's got little kids, so I'm guessing he's not going to do it unless it can be done right. Naval architect? Draw plans up and execute the construction yourself? That's how I may approach it if I were doing this. I can tell you my upper deck is supported pretty robustly by the enclosure around the aft deck. I think you can bring that load down pretty low in the hull leveraging the structure. I'm actually always amazed that the Davit supports the whaler, as it just goes through the deck and mounts to the lower deck I the "back porch". Definitely more complicated than Dans great work but really interesting to watch.
How far over is the cantilever going to be? Is anything heavy (people, dingy, etc) going to be on the cantilevered section?
Or did I mis-understand, and it's going to be fully supported from below. Putting supports up and just making a raised floor is pretty simple. Making a solid cantilevered structure, not so much.
You know me...spend the $47,000 and get it done right the first time. Besides, what will you do with the rest of the salvage boat when you are done? Hey. It's a legit question.
Hi guys came into this thread late but had to say that we did this extension on our 58YF and use the top as a lounge. We closed off the fly bridge with canvas and extended the hard top of the aft deck which is canter levered about three and a half feet and also placed a hard top on the fly bridge. It is amazing how much space this creates. I will try to send some pictures tomorrow so you can take a look at what we have done.
I will take some shots closer up and from inside for you to see. We brought the rail out to the edge so that we get use of the full width of the top and changed the steps leading up to the fly bridge by building a teak stair that starts from the stb side of the aft deck. We are able to seat three or four on a dock box that backs the fly bridge and we have three lounge chairs along the back rail so a total of six can relax up on the sky lounge as my daughter and her friends call it.
