Economical hatch screens can be got at most "Dollar"-type stores. Two per package. Held in place by a suction cup & string. On my 1997, H376 it takes two for large forward hatch, & one each on midship hatches. They also reduce sun glare, so I use four across the long topside window. One could use them on side windows too. Let's see, for me, that's a total of 8 screens at 2 for $1. Sure beats the $37 apiece the French & other Europeans are paying. N'est pas !!??!! C'est domage !! : o I also use them on my car door window to reduce sun heat & glare. They work great ! AND, the price is right !! ; } :dance: Hope this helps. Fair Winds.... MRF
