Is there a good book focused on the disaster and itβs ramifications for English history? I looked but am unable to find one.
The short answer to your question is that I know of no book specifically devoted to he disaster β and perhaps that's not too surprising; the only information that we have about it comes from several brief chroniclers' accounts (notably those of Eadmer, Orderic Vitalis, William of Malmesbury and Henry of Huntingdon, each less than two pages long), and the ramifications, while very important, are relatively straightforward to trace.
Probably the most complete account you're going to find of the latter come in Warren Hollister's Yale bio of Henry I (pp.276-82, 458-60 in my 2001 paperback edition). Hollister gives excerpts from the 300-strong passenger list (an eminent one), which included
The most important person not to board was Stephen of Blois, the future King Stephen, whose succession to the English throne 15 years later was in large part a product of the death of William Adelin, which left Henry with only one legitimate child, a daughter, the Empress Matilda (never to be confused, of course, with Stephen's wife Matilda of Boulogne). Stephen was due to cross on the ship but came down with a stomach complaint before it left port; Hollister comments that "his diarrhoea probably determined the history of England between 1135 and 1154."
Other consequences of "the most catastrophic maritime disaster of the Middle ages" noted by Hollister were:
Hollister goes further, though, in suggesting that the disaster prompted in Henry the works of "his most serious and productive years", which included the administrative reforms that began to produce the famous pipe rolls β royal accounts that offer us unparalleled insights into the finances of England from 1130.
