"Astragale" is a Mason 33s designed by Al Mason in the late 50’s.

Professionally built in 1974 by Paul Mailloux of Mailloux Leclerc shipyard in Île-aux-Coudres, Charlevoix QC, using mild steel. Deck and hull plates are 1/8 of an inch, keel plates are 3/16 of an inch.

In 2004 ASTRAGALE was transported from Ontario to Quebec city were she underwent a complete and thorough refit.

A thorough inspection of the hull was conducted and a section of the bow, chain locker location, was replated with 3/16 of an inch by the son of M. Mailloux, who works as a professionnal ship welder.

A dog house was added, 1/8 of an inch plate, to have an inside watch area with a collapsible seat. Portholes made of lexan 3/8.

"Astragale" was back in the water in 2015 and navigated St-Lawrence river and the Maritimes.

The interior finish is to yacht standards; a great opportunity for a couple looking for a strong pocket cruiser to explore remote coves and bays.

Fully equipped for cruising with recent survey available on request.

The boat is currently located at South Shore Marine in Chester Basin, NS. 

There is a 2021 survey available for serious buyers.
