Roberts Ultra 44
Description
The Bruce Roberts Ultra 44 is a 44-foot cruising sloop designed by Bruce Roberts-Goodson, emphasizing a generous sail plan for superior light-air performance and efficient upwind sailing, making it suitable for coastal or offshore passages with a focus on speed and handling. As part of Bruce Roberts' lineup of DIY-friendly plans, it's intended for amateur builders using materials like fiberglass, steel, or aluminum, though specific construction details are sparse in public records—this model appears less common than staples like the Offshore 44, with limited builds documented. The rig supports a large working sail area exceeding 1,200 square feet in genoa configuration, paired with a modern Bermudan sloop setup for balanced power, and while full hull specs (e.g., displacement, ballast) aren't detailed online without plans, it's positioned as a performance-oriented cruiser for families or couples seeking adventure on a moderate budget, with total build costs estimated at $80,000–$150,000 depending on materials.
