With over two years of in depth research and decades of experience to draw from, the 27 Shadow has emerged as the premier big lake tunnel boat. The 27 Shadow stands alone with its unique styling and stunning attention to detail. The hull is a double-stepped, ventilating air-entrapment design that thrives on big lakes. With Ultra Custom Boat’s renowned cutting edge design you will be amazed at how the 27 Shadow handles heavy lake chop, yet remains responsive when a slower pace is called for.
When we undertook the design of the 27 Shadow, we had one goal in mind, the ultimate big lake family tunnel boat. From the well-appointed functional cockpits, to the stunning performance of an amazing hull design, the 27 Shadow is without a doubt an amazing fusion of design and function.
