Overview

The Princess 35 is one of Bernard Olesinski’s most respected designs, pairing classic British styling with strong seakeeping and performance. Built in Plymouth by Marine Projects (now Princess Yachts), the Princess 35 quickly earned a reputation for quality construction, practical accommodation, and confidence-inspiring handling.

Katy Em is a superbly presented 1989 example, fully surveyed in November 2024 with every recommendation completed, and extensively upgraded between 2024 and 2025. Powered by the largest engine option, twin Cummins 250 hp diesels, she delivers a brisk 28-knot top speed with effortless and economical cruising.

Benefiting from comprehensive mechanical care, new electrics, a fully refreshed interior, upgraded safety gear, and UK Part 1 registration, this Princess 35 is genuinely turn-key and ready to enjoy.

Owner’s Comment:
“This is a fine boat in excellent condition with all issues from the full survey in November 2024 completed. The largest engine option gives her sparkling performance and very economical cruising.”

Broker's Comment:
Katy Em is a rare find: a Princess 35 that’s been meticulously upgraded to modern standards, mechanically verified, and cosmetically refreshed. She offers a perfect blend of classic Princess pedigree, lively performance, and turnkey readiness, with UK Part 1 registration, recent survey, and comprehensive documentation.

This boat represents an excellent opportunity to acquire a properly cared-for, extensively refitted British cruiser that is genuinely ready to step aboard and go.
