This awesome Rock Diving with a Tunnel has 4 diving platforms. The 2 highest platforms are the same height as are the 2 lowest platforms. (26 1/2' and 14 1/2' respectively.) This was created for my Ocean Breeze room but was also created for my "4 Pose High Dive" (PID 42577115) that works perfectly on the top 2 diving platforms. There are also 2 standing nodes on the top of the rock to help you add your favorite Hang gliders or Hot air balloon. The tunnel was made for my jet skis to go through and works perfectly! Please try before you buy.. No refunds will be given.
