Charter yacht MV Last Call, which cruises from Alaska to Mexico, needed a modular, multi-season sundeck enclosure so guests could enjoy the hot tub no matter the latitude. To properly outfit the 40.3-meter (132-foot) luxury vessel, the planning and fabrication had to be meticulous.
What began as a three-sided enclosure with four panels on each side grew to later include the aft section of the sundeck.

“The outermost panels remained fixed, while the adjacent inner panels could slide behind them,” say the notes for the winning International Achievement Award entry, written by Derek Newcombe, MFC, of SALTY BUOY Marine Canvas Inc., of Vancouver, B.C., Canada. “The enclosure initially spanned 16 feet per side and 18 feet across the front, with a height of approximately 3.5 feet from the hard top to the surrounding railing.”

Chief among challenges was developing a fastening system. “The polished stainless-steel railing, enhanced with smoked acrylic panels, eliminated conventional installation methods. To overcome this, a keder-to-zipper mechanism was devised,” Newcombe writes. The brackets were designed to align so perfectly with the canvas that they would seem original to the boat.
It was essential to guests and staff alike that the enclosure be able to be opened with one hand, so the system has a hockey-stick zippered path. A second rail allows the width of the opening to vary.

In the end, “the entire enclosure encompassed nearly 80 linear feet,” and work on it included prototype scale modeling, testing how to bond PVC to clear acrylic, and creating and sourcing custom components.
The enclosure was one part of a multimillion renovation of the boat, completed in 2025, that took several years.
