The first project I tackled when I bought my 1998 H310 in 2004 was to replace the hatch boards with doors. I made a template from scrap cedar I had around the shop for fit and then made the final doors with mahogany. My only regret is that I didn't design them to be able to interchange screens with the plexiglass panels. Overall I am pleased with the results. I could have purchased commercial made doors but there is more satisfaction in making your own. If you have the tools and ability, go for it as I did. I have had several positive comments on my handiwork.
