MCA COMPLIANCE FOR VESSEL MODIFICATIONS
It is vital to the safe operation and compliance of commercial vessels that stability information and structural assessments are kept up to date. When modifications to a large RHIB together with a change of operations were proposed, Pratt Naval Architecture were commissioned to update stability information and provide technical information which enabled the vessel’s certification to be maintained. Drawings were prepared and the structural modifications analysed. Weight estimates were prepared and enabling the vessel’s stability information to be brought up to date.
HRH THE PRINCESS ROYAL HONOURS EXCELSIOR TRUST
HRH The Princess Royal commissioned the “Excelsior” as a sail training vessel in 1988. She returned on 28th March 2023 to re-commission the Trust’s 1906 Gt Yarmouth Shrimper “Horace & Hannah” at Ipswich. Pratt Naval Architecture were delighted to participate in this special event having worked with the Trust for several years.
STABILITY INFORMATION BOOK
Frosty still weather! ideal for an inclining experiment and lightship survey before we prepare stability information for MCA approval. Our highly accurate datalogging inclinometer did sterling work once again. If you are certifing your vessel for MCA Coding or other commercial use or merely wish the information for peace of mind we can prepare intact stability and damage survivability information. Category 0? Lifting equipment? Towing? Ice accretion? No problem!

PASSENGER VESSEL STABILITY COMPLIANCE
Pratt Naval Architecture were pleased to be tasked to scan, advise on draught marks and carry out an inclining experiment and prepare intact and damage stability information for this 26 m steel vessel. Suitable test weights were also arranged. The scan encompassed both the external and internal parts of the vessel giving an accurate representation for the naval architecture work since drawings were not available.
MOTOR YACHT NEWBUILDING
Pratt Naval Architecture were pleased to be asked to oversee the construction of a new 14m Motor Yacht equipped with twin IPS drives, built by a well known UK builder. Periodic visits were made during construction at strategic stages from moulding to completion, liaising with the production manager and staff to address the issues found.
FROM OUR ARCHIVES 5th January 2021
Adequate stability is an essential safety requirement for pleasure and commercial vessels. We have the knowledge and sensitive equipment needed to safely assess stability of all kinds of floating vessels to modern standards without resorting to the somewhat risky approach adopted in this 1912 photograph!
“COMMUNITY SPIRIT” – OFFICIAL LAUNCH BY HRH THE PRINCESS ROYAL 14th October 2020
Director, James Pratt was privileged to be invited to meet HRH The Princess Royal at the Official launch of “Community Spirit” hosted by her owners, Crusader Community Boating. Pratt Naval Architecture were tasked by the vessel’s builders, Colecraft Boats, to design the vessel to meet the particular requirements of the charity. The design incorporates a hybrid propulsion system making maximum use of the available shore power system and onboard solar panels, with built in features to enable future upgrading. Flexibility of operation is ensured by passenger lifts on both port and starboard sides.
