Paul: Yeah I know what you mean by warping solid teak hatchboards. I had a beautiful set made by JOWoodworks for my M17. I also had a set made of marine plywood. The plywood were for when 'boat in storage'. I used the teak when cruising. During my 10+ week liveaboard stretch in 2018 the boards slowly warped from the occasional rain, morning dew and constant humidity. I was constantly sanding the board's ends fit behind the companionway's grove. If I had kept SWEET PEA my plan was to but some stainless steel bars (stringers) on the back side of the boards to keep them from warping. SWALLOW, my boat/home also has solid wood companionway boards. One of the two warps with the temperature: warmer it is more warping. :: Dave Scobie :: M6'8" #650 :: SV SWALLOW - sv-swallow.com :: former owner M17 #375 SWEET PEA - m17-375.com :: former owner M15 #288 SCRED - m15namedscred.wordpress.com <<-- new site!

The reason I need to make new boards is because I tossed the original ones after making beautiful solid teak boards. They warped, even after I glued them up properly according to the grain. Plywood is generally more stable than solid. You guys got lucky. Paul

I agree with Mark on using solid wood. I used mahogany to make my hatches for Seaweeble. I just routered the edges and they’re still sliding easily after several years. If you don’t want to spring for teak or mahogany you could try ipe ( yes, i-p-e). It’s very dense and cheaper than teak and very strong. It should work well also. Ian M-17 Seaweeble M-15 Judi B

I used solid lumber rather than plywood for the hatch boards on my M23. I'm very pleased with them. The boat lives in a slip on the Oregon coast for 3/4 of the year in all kinds of weather. I made the hatch boards at least 10 years ago. I simply routered the edges sufficiently for them to slide easily behind the companionway cleats. The nominal thickness of the material was 1". I pretty sure the wood is mahogany, but I don't remember for certain. Mark Dvorscak M23 Faith M15 BC
