This is a Seitech sailboat rack for a trailer that carries two boats up to 58" max beam. IT DOES NOT INCLUDE THE TRAILER! I bought it to carry my Laser and Sunfish, and don't need it any more. It attaches to a Karavan/Shorelander trailer with three "U" bolts (included) and allows you to carry two Lasers, Sunfish or other small dinghys with ease and utmost security. It is made of structural grade anodized aluminum and hardened plastic joints which are connected with stainless steel bolts and lock nuts making EXTREMELY durable and strong. It assembles easily with a phillips head screw driver. There are a few superficial scratches and tape marks on it but it is in very good shape overall. This exact rack sells on Seitech.com for $745. Used ones do not come up very often. I am asking $500. Please contact me at 847-226-1109 for additional information.
