Forward Hatch
I used an aluminum Bomar 20"x20" (nominal) Low Profile to replace the original equipment Plastic hatch; it was an almost perfect drop in fit on our 1986 28.5.However, when replacing the 10"x10" (nominal)mid bay hatch, I had to use an orbital sander to widen out the opening 1/4 to 3/8" and re-seal the edges with Marinetex. toget a perfect fit.See the hunter 28.5 web site for many projects and discussionsspecific to this model:www.huntertwentyeightfive.com
