I think my Ericson 25 full keel would just bump in the surf on the Galveston Gulf of Mexico bottom and not be pushed over in the surf. Often the Gulf is as flat as a table, or small ripples, and the summer calm period is boring. Yes in bad conditions don't take risk but I THINK LOOKING AT THE FORCES most sailboats are NOT in danger on a very sandy and very flattish sea bottom next to Gulf of Mexico. People do this parallel beach cruising in Miami, and we do NOT see many people dying being pushed on the beach. I often am pushed by wind into the muddy shallows of a creek here, and my keel sorta acts like a safety bumper, in small waves and surf it just will not be tipped over or hurt.
That Columbia Carbon 32 in that beach surf accident was a racing boat so delicate, and was in high surf. It did roll over in the surf, and then life vests malfunctioned... . But IMPORTANANTLY it has a retractable keel to allow trailering, so I bet that came up and was flush with the bottom and then the ship rolled, the waves on that accident night seem Medium not large and certainly not Gulf of Mexico calm. This is unlike a Ericson 25 full keel, which is so heavy harder to roll. The Columbia was also tippy with just a small bulb keel, like 1700 out of 5000 pounds.
"""it's NEVER a good idea sailing close to a lee shore""" It is sorta NOT a good idea to EVER go out in boat, can hit a pipe, run aground, fall overboard, hit your head on something metal. Sooooooo, if one is scared of even low 1 in 10,000 risk then logically don't leave the marina. Im not trying to over argue, my only point is given all the factors are we exaggerating in low waves how risky is "being offshore near a beach in sailboat", it seems low risk in LOW wind and waves. I was raised on a river and was always scratching the boat or running aground and would have to power off or swim under and scrape, only at CLEARLY MORE ENERGETIC WATER TIMES LIKE flood times would we REALLY feel a boat could be tipped, and same with little surf on the ocean, again the Gulf of Mexico is usually flat or small ripples in summer...
Motors have also improved and rarely fail, I am amazed by 4 strokes. In the Columbia accident they lost the rudder and even with motor couldn't steer from shore, what a weird accident... Basically, maybe on CALM DAYS LOW WIND AND SURF IT IS SAFE ENOUGH TO PARALLEL THE SHORE..
PS. The 1 good thing about Texas is no rock just sand and mud, that is far less harmful to bump into, can such sand and mud EVER crack open a fiberglass hull no matter the pounding in surf???? California due to geology has hard jagged rock.
