Hi Frank. No, the 33's did not have an intentional hook designed into the running surface, on any year hull. Over the years, as boats change hands, they are stored & therfore supported in different ways that effect the straightness of the bottom. Trailer bunks, boat lifts & cradles should always have their main support bunks run all the way to the transoms trailing edge, or beyond. Hi & Dry forklifts are known for poor support during lifting & lowering sessions. All this aside, all boat fiberglass post-cures for years & actually strinks with time. The fiberglass shrinks, but the transom wood & stringers don't. This will leave a small(and sometimes not so small) hook at the trailering edge of the bottom of the transom. In the business, the slang term for this is called a hard-spot. Most boats have them. How severe one boats shrink rate is, versus another, depends on the type of gelcoat, resin, catylyst type, strength, & quantity was used during its lamination process. The number of layers & types of glass used, the shops ambient temperature, as well the length of time between laminations, mold cure time, etc., also come into play when designing the amount of shrink time designed into a fiberglass part. There are many other factors as well, which I won't go into.
