I think I’d be concerned in two primary areas with a GB on such a crossing, and both are water intrusion based.
I think you need to assume you will experience weather a good bit more that forecast, and you need to be comfortable that your boat can handle it. I had a 47 GB, and based on that I’d be most worried about windows getting knocked out, and water in the cockpit with subsequent loss of stability and down flooding.
The GB is a pretty low profile boat, so I think you need to be comfortable that it can take a slug of water on any window and not have it get blown out. If a window get knocked out then you are in really deep short. I just have no idea how thick the glass is, size, and what ABS or other rating it achieves. So I’d want to understand that, and reinforce as necessary as others have described.
The other thing is down flooding, especially if you have a cockpit than can be turned into a swimming pool. But if you have a GB classic layout, this might be less of an issue. Either way, I’d really carefully evaluate down flooding opportunities assuming the boat is completely awash for extended time.
