I’ve had a waquiez gladiateur for 5+ years and can easily recommend the design and build quality. The glass work is excellent, the bulkheads and hull to deck are fully glassed , a very sturdy and quiet boat.The deck is balsa cored but in small squares and all hardware mounting areas are solid glass. The interior joinery and finish quality is very nice , all above waterline interior hull is lined with teak , molded fiberglass headliner with access panels. Check the connection of chain plates to hull under the settees which is bomber but could be affected by leaky deck fittings. The hull on my boat is epoxy coated and no blisters but this is another thing to check. My boat has drive shaft so no saildrive experience.
They have a masthead rig with a high aspect main, old school but balances well. Will sail to hull speed (7+kn) in 15kn wind, but in light air you are looking at a big genoa or asym to get moving. This design was done by Holman & Pye , London , built by Waquiez so good bones. They have a nice motion, carry momentum well and feel solid in heavy weather . The cockpit in this boat is nice and comfy to stretch out or sleep.Headroom is about 6’2”. If you could get this level of quality in a boat built today it would likely be expensive.. Good Luck!
