Sunny,Pretty sure that the O'DAY 290 is just a retooled CAL 28-2 (early to mid 1980's, Hunt Associates Designed CAL 28, not to be confused with the mid-late 1960's Bill Lapworth-Designed CAL 28). The interior of the O'DAY is the same as the CAL, and you're not the first CAL or O'DAY owner to notice that. Most of the difference is that modified transom.
