keel the messenger
The HOW specs page shows that your model was made with either 4'-6" draft or 3'-3" draft. I'm not real familiar with your model but it looks to me like it was offered in fin keel or wing keel options (both are pretty self-explanatory, if yours has wings on the bottom then that's it) A shoal draft keel is a shallow draft keel, sometimes retractable, made for shallow water sailing. One of the advantages of a wing keel is its shallower draft.
