As an additional thought, if you're thinking about adding an extra set of hand holds on the cabin brow as an assistance when going forward to the bow of the boat, such as to raise anchor, a second pair placed on the top of the trunk on the side and slightly behind the hatch would be another, perhaps even more important addition.
Just get up there on your boat, imagine the whole boat and especially the bow pitching around, and figure out where the two sets of handholds need to be to get you from the long handrail on the top of the cabin to the bow pulpit.
The placement of the one on the brow may influence the placement of the second, but it will become immediately clear that there is a open area between the cabin and the bow pulpit with nothing at all to hold on to.
The only other approach that I can think of would be to use a rope attached between the bow pulpit and brow as a handhold, or pick up the forward "painter" (sailor's term for bow dockline) and hold it during the forward passage.
Rigging a removable line between the brow handhold and the bow would be a smart move it one suspected the weather was going to turn bad, but you can't always anticipate that ahead of time, like the night before when anchoring in calm conditions.
Just something else to think about. And another good reason to add a windlass to raise anchor without going on the foredeck, although a fouled windlass can force you up there just the same!
