I'm not an engineer but I do re-engineer many systems they dream up. I think the fixed windows do add strength and without them the structure has to be weaker. They help support the coachroof which does create an arch between the flatter deck sections.
Also, floorboards. You might stiffen up an old design by changing from wooden plywood to an aluminum honeycomb sandwich. But would the cost be worth it? Probably not unless you needed to replace them. ----- Original Message ----- From: "Frederick G Street via CnC-List" <cnc-list@cnc-list.com> To: "dwight" <dwight...@gmail.com>, cnc-list@cnc-list.com Sent: Thursday, February 12, 2015 2:53:25 PM Subject: Re: Stus-List Window Installation - 1985 41 Dwight — if I might jump in here, my understanding is that the glued-in acrylic ports became a unified part of the cabintop structure, and stiffened the structure; NOT that they made the boat stiffer in terms of sailing characteristics.
