David Marlow, originator of growing line of Marlow Explorer Yachts, shows Capt. Bill Pike his latest and greatest--a proprietary tender design manufactured by Norseman Shipyard in China and called the Marlow Sprite. As with other Marlow vessels, the Sprite has a fit-and-finish second to none. Consisting of a foam core sandwiched between inner and outer moldings (with non-skid decks to perfectly match the mothership), it is also unsinkable, according to Marlow. Pike, a saltwater flycasting aficionado, suspicions the little craft might make an excellent back-country fishing skiff. Marlow wholeheartedly agrees.
