I have found what we think is a 1980, 19' haskal tunnel hull with a hin of ....HMNT1336M801. The owner thinks it is an 83 but is not sure. It has a AT pump and has been converted to a BBC with a 512 block and Iron heads. The owner thinks it is a 427 but I imagine it is probably a 454. It has a very flat keel wich looks like a very long delta pad. The shoe sets lower than the keel. Any one know anything about the Haskals and if so how good of a hull is it and what is the good and bad. I thought I could add a dropped keel and set the pump back this winter if I bought it. Thanks in advance.
