The Itama 45RS is the smallest model in Itama's current production range, with an overall length of 13.82 metres, beam of 3.95 metres and draft of 1.33 metres. Itama's history dates the RS restyling to 2023.

Twin Cummins QSB 6.7 engines rated at 550 hp each drive the yacht through shaft-line transmission. Published performance is 34 knots maximum, 29 knots cruising and 200 nautical miles of range at cruising speed.

The current product material presents alternative lower-deck arrangements rather than one unambiguous single accommodation count, so Luxury Yacht Guide leaves the structured cabin-count field unset while retaining the official configuration information in the source record.
