John here is what I did added this piece of unistrut from Menards to the front of the boat, mounted on wench stand ,everything bolted in place ,no welding or drilling. for the top .1 pcs of unistrut connector 1 u bolt and a garden rake or shovel holder. For back. 3/8 rod 2 clevis pins 1 garden holder 1 wire rope clamp. This might work for you ,I have the same tabernacle on my mast ,everything stays hooked up , It sticks out about 2 feet over the front of the tong and 1 foot over the back. Working on a carrier for the boom . The unistrut comes galvanized also ,they were out.
