We've installed gutters from Essential Products on IBIS (NP43 #24). It's a sticky-back, off-white marine gutter 44-M01 at $1.95 foot for custom orders. We ordered 10 feet, but ended up short on wrapping the gutter all the way around the front windows and side doors. You'll need some 12 feet of gutter material to cover the windows and doors. The off-white matched our NP43 white nicely and we placed the gutters above the pilothouse sliding doors. The product works well but may need aa small holding screw when rounding tight corners.
