hatch
 

Spare, i did not know that one , I'll keep it in mind thanks. But next time i will be using Formica for my mold material so that wont happen again. I just finished gelcoating the hatch this morning and it looks good ! I us a textured roller that is made for applying contact cement,it has a slight stipple to it and lays down a very nice pattern. Ridge i really enjoyed our conversation yesterday as well, thanks again. I will post pics of the finished hatch this weekend.

once again i must ask the v20 gods
 

Ok so here is the finished product, 1st as you can see is the core. then of the mold removing disaster, scratches from the dewalt power planer that i had to use to remove the MDF, then used poly filler to repair, then re gelcoated with stippled roller used for applying contact cement.

Yup!!...that really looks great!!...nice job...:clap:

It turned out great. It should offer more grip and strength than the Starboard.
AND The coring was done right IMO. Leaving the core just shy of the outside edge is a strength multiplier. The glass that gets put over that rounded edge and back up the lip forms a much more robust design. Another advantage is upon screwing the lid down around the perimeter, no screws will be into the core. You just want to make sure the hatch face is thick enough in that area to be able to easily countersink the screw heads. That is where Whaler has screwed up on their lid and hatch design IMO. They run the core to the outside edge and then proceed to fix brass nuts in place to be fancy then the back side of every lid is glassed over and gelcoated. They rely on caulk around the fasteners to keep the water away from the core, same holds true with keeping water away from the foam sandwich construction in all the thru hulls.
It looks nice and foo foo having a slick gelcoated back on all the hatches like the Whaler lids but several lids failed at about the 6 year mark due to their construction techniques. I built my hatches like yours and they are already older than that ,still perfect.

and now i can seal the gap between the hatch and deck and not have water dripping on my gas tank .:time:

The hatch fit like a glove , how funny is it that 3 weeks ago i had no clue how to do this and today i have a costom built hatch . now i start on my helm seat box with tackle storage :head:

can anyone tell me how wellcraft origionaly fastened these gas tank hatches . Was it countersinking the screw heads or using SS finish washers. Thanks
