Attach velcro with self stick glue and 1/4 inch screws every 12 inches around the inside of your companionway. Attach the mate velcro to a piece of screening cut to the same size as your companionway. Simply press the velcro screen to the companionway to install. Pull to remove. With the forward hatches open (and screens pulled) you have a nice flow of air below while at anchor or tied up dockside, and no bugs!!!
