Thanks for your comments. Unfortunately you miss-read what I wrote there, and on reading it again now I can see why, and that it is my fault and I should write things more clearly on this forum.
Anyhow, what I said (or meant to say) was that the davits cost us approximately 25% less than if I had ordered similar davits to be welded up and made for our boat by an Australian davit maker. Twice before I have had davits made here in Australia (once for an Island Packet 40, and the other for a South Coast 36 design) and each time we spent approximately $15,000 AUD on these. However neither were as well made and as large as the ones from Turkey so I assume such a set would be a fair bit more for an Amel 53, possibly around $20,000 AUD. Therefore Emerek's price was 25% cheaper even after all the duty etc.
Although Australia is a beautiful country to cruise in and visit, unfortunately it is a very expensive place for boating works and equipment and this is why we took the opportunity to add many many things onto our Amel such as a new 100 l/hr 240v/24v duo watermaker, a second full auto-pilot with quick change over switch, new radios, GPS, AIS, Sails,.......etc etc when we had our boat in the Canary Islands in 2011 as it was so very cheap there compared to doing all this work back here in Australia.
Also the solar panels and controllers were very reasonably priced - we got two 260w panels (total 540w) plus a Tracer MPPT controller with MT50 display all of which did not cost much at all (purchased new on E-Bay) and which we installed ourselves. So I would think that Kent's proposed budget of US$18,000 is actually a very realistic figure to have all this equipment added. I would be surprised if it cost him more that that.
Please don't think that you disturb me with your questions at all. Quite to the contrary questions from very experienced members such you on this site is of great benefit to us all especially since you have now more that 20 years experience sailing an Amel. This is what actually makes this site so valuable in my view.
