Pipistrelle – Wauquiez 48ft Pilot Saloon – Hull No. 27 – built 1999 – launched 2000

Wauquiez

Background

Wauquiez’s yard is in Lille, northern France, and the company was founded by Henri Wauquiez. It “was committed to build fast seaworthy and safe yachts, of durable quality”.

When we purchased Pipistrelle we knew from marine publications she was a well-built yacht, but we did not realise just how good the manufacture actually is.

We understand the yachts were constructed well until 2003 when Beneteau bought the business, to sell it shortly afterwards to an investment company, which then went bankrupt.  The Wauquiez company started trading again in 2013 with friends of the Wauquiez family at the helm, and we understand the quality of build has reverted to that of around the millennium.

Notes

Max Prop 3 bladed propeller

  • Pitch design                20 deg
  • Manufacturer             PYI Inc
  • Engine produces        100 HP at 3,600 rpm

We found shortly after we bought Pipistrelle, that as soon as we increased the engine revs above 2,500, the engine overheated.  We had the engine checked, it was not causing the problem.  Through the Wauquiez Yahoo Group, we learnt that as an engine tires, the pitch of the propeller needs to be reduced.  We contacted PYI in the US, who confirmed that with the Yanmar engine, the pitch should be 20 degrees, but also provided the pitch settings for 18 and 16 degrees.  After discussion with Riccardo in Krabi Boat Lagoon, Thailand, he reset the propeller to 18 degrees.  We then ran the engine at 3,000 rpm, achieved 8 knots, and the engine did not overheat!

PS: Pipistrelle by Wauquiez is not a simple Pilot House (PH), but a superb Pilot Saloon (PS)!
