I have many j30 parts for sale including a custom stern rail arch and bimini. It is only slightly heavier than original rail and does not interfere with backstay or boom but gives a place to mount items and gives good amount of shade. Bimini cloth not included. Many othe parts including a great running yanmar with trans. Ask about any parts you may need. will email pictures. email jmirschel@msn.com or 9044763373
