ideas for a new cover for '92 ski nautique closed bow?

[STPHNSN23]

admittedly, i haven't even opened an overton's catalog yet, but i'm trying to get my dad a new boat cover for father's day. the boat sits on a shore station with a canopy all summer so the cover is mostly just to keep the dirt and dust out. i don't want to install snaps since our current cover doesn't use any. when we trailer the boat to the lake in the spring and home in the fall, we take the cover off so that isn't an issue. it is stored in a barn over the winter and will be covered so that may be a consideration.

any thoughts?
