If you are building to a standard, you need to choose hatches that meet or exceed the standard. For instance, a yacht built to European standards would meet an appropriate design category and be approved and documented under ISO 12216. Category A is ocean. An example is here (for Vetus)...
If you are building an offshore boat and you expect the hatch to be as strong as the deck, you have to pick an appropriate hatch. Most are nowhere near equivalent to the deck. For most yachty purposes this is an acceptable compromise. Just not for all yachty purposes.
Most hatches on pleasure...

The windows on the GB are not "protecting access to spaces below" and not an issue at all. The damage to the companionway was important...
Turn of the month max sig wave ht at that buoy I referenced was only 4.4 meters.Max winds 17 gusting 20 m/s.
I have no doubt yuo'd go offshore in a GB 55. That's not what I'm asking--nor what many others are asking. We are wondering would you go offshore in the WINTER? Because that is not the...
On the 2nd Feb the at South Hatteras sea buoy (NOAA) sustained winds peaked at 18 m/s (gust to 22 m/s) and sig wave height topped out at 6 m. The gale on the 5/6 Feb was less than that. on the 11th the storm was 23/28 m/s and 10.4 m sig wave height...again this is to be expected in those...
I just thought of something. It would be interesting to know whether that Crowley ship had a recording anemometer, and what it said...not that it would be definitive but still, it might be indicative...
