My point is that you can read too much into a biblical allegory, especially when trying to read back from the allegorical interpretation to build up details about the OT passage it is drawn from. You can't claim that Hagar and Sarah were particularly tall because Paul said they were allegorically mountains, or that the passover lamb must have been particularly skilled at carpentry, for a sheep anyway. You simply can't say "This adds to the allegorical picture therefore it must have been so."
Now the water in the Red Sea must have been pretty deep normally, the Egyptians drowned in it, but you can't say it must have been deep to symbolize immersion, you can't even say it was that deep from the passages quoted. It says in Heb 11:29 By faith they passed through the Red sea. The same word translated passed through is used in Paul's vision of the man from Macedonia telling him Act 16:9 "Come over to Macedonia and help us." In 1Cor 10:1 'through the sea' uses the same preposition 'dia' as Matt 12:1 At that time Jesus went through the grainfields on the Sabbath.
Even if they were below the normal sea level crossing the Red Sea, it does not mean the waves must have been higher than the ark because it makes such a nice symbolism. It simply does not follow.
You are using absurd examples to make your point. No one would think that because Sarah and Hagar were compared to mountains that they must have been tall. Same with the passover lamb/carpenter thing. This is borderline strawman.
But the bible does liken the other events to baptism (I presented the supporting scriptures). My idea of the ark being submerged at some point is based on my belief that the ark was very heavy and barely floated. This would enable it to handle any large swells without damaging the craft or seriously upsetting the critters on board, and by the way
also fulfill the baptism type.
The Red Sea crossing is just too perfect a type of immersion baptism.
Truth is there are lots of blanks to fill in, lot's of space between the lines. As long as we don't change anything we can enrich the stories with assumptions and conclusions that clearly make sense while retaining the integrity of the stories.
For example, the bible doesn't give much detail about the construction of the ark save the materials, size, and a few other details. But if we construct a picture of what probably happened a whole city of workers appears, complete with dwellings, markets, roads, etc. Supply lines both by land and water, a bustling landscape of activity surrounding the project. At the center is Noah and his sons as general contractor and foremen directing the great work. But the bible is silent concerning this saying only that God instructed
Noah alone to build the ark; a task impossible for lone person.
It was only recently discovered that a whole city like I have just described was uncovered surrounding the great pyramid at Giza. Prior to it's discovery no one imagined what the site
must have looked like during it's construction; a workers village that permanently housed at least 5000 workers believed to be just the artisans and stonecutters. Many more thousands of laborers would have lived in tents in the nearby desert.
You can enrich the stories, give them deeper meaning, without mistranslating or misinterpreting them.
