The 2005 Post 50 Convertible "Backlash" is a clean, fully updated sportfishing yacht designed for both serious offshore angling and luxury cruising. Built on Post's respected hull design, she delivers confident handling, solid performance, and timeless aesthetics. Powered by twin MTU/Detroit Diesel Series 60 engines (825 HP each), she reaches top speeds of 34 knots with a comfortable cruising speed of 25 knots.

The interior showcases Post’s signature high-gloss handcrafted teak woodwork and modern laminate wood flooring throughout. Natural light floods the main salon through large windows, leading into a fully equipped galley and leather dinette area. Below deck, a 3-stateroom, 2-head layout offers comfortable accommodation for owners and guests during extended stays.
