Greetings:
I solved the "slippery deck" issue in the pilot house of my 2520MV by using some deck tread strips. They are non-skid grit embedded on the top and adhesive coated on the back. Installation is simple; clean the area well and wipe with acetone or someother greaseless solvent, peel off the paper backing from the strip and apply the strip to the deck. Once applied, they remain solidly adhered and don't come off when it's time to scrub the deck. I think that they are a 3M product (found mine at one of the big-box stores.
