Was used on a 2004 Mainship 400 trawler. All the parts are there but a few aluminum backing plates and 1-2 S/S bolts are missing. See the system at their website https://seawisemarine.com/
I bought this used for my mainship 400 from another owner but decided on a dingy bigger than I wanted to use it on. So it's back for sale. New about $4500.
Asking $1200 and first $1000 buys it. Buyer pays shipping.
Can be picked up at 77565 zip code also.
Happy to send pictures.
