I might know how to contact one of the glass guys that worked for Tom Stolarz laying up the Team Warlock's 25 years ago. I will try and reach out to him and see if he has any cloudy memories (smoked a lot of glass) that could shed light on your left hand leaning issue. Stolarz tooled the molds for the 23 and 28 Offshores from scratch. The 28's were a brand new design at the time.
I know of the guy who has the first production 28 Offshore ever built. It is a 1987 HIN and located in Washington state. It has twins so no help for your leaning issue, but given his is a 1987 and yours is a 1989 any tweeks to the hulls bottom would have been sorted out two years later. His is the only 1987 28 I have ever seen.
