The base cost for that design of frame is around $1800. It's 4 1/2 bays and is the longest frame you can put on that boat, 91". The mini bay fits two rockets perfectly and we extended the floor for them to sit on it. Depending on what cross bars you want adjustable, how many cut outs, rigid floor or floating, hatches or tables etc will determine the total cost. Look at the website for other frames he's made which start around $1000.
As to weight we never weighed it so I'm not sure about that, but two people were able to lift it onto the boat on it's trailer without much fuss. It's trailered and lives there so I will only have to lift it once or twice a year to clean the boat.
