This attraction was met with unscheduled refurbishing and mechanical problems in the early part of the 1990's, that eventually led to it's demise in 1994. Prior to 1994, the submarines in this attraction were all removed, the water drained, and the "tank" cleaned out and re-painted. The subs were also re-painted to a bright red color. After all of this work, they eventually decided to pull the plug and officially announce the discontinuing of this attraction in 1994. With that in mind, one must assume they had big plans for this ride, still involving submarines, and some unexpected problem must have surfaced (no pun intended) preventing this ride from returning to full capacity. People have speculated that the reasons for discontinuing this attraction have been slow loading and unloading, long lines, limited or no wheel chair access, and above all, high maintenance costs.
