Original in Power Boating, Completely Refurbished!

Perhaps no boat in power boating history has equaled the worldwide popularity of the original deep-V - the Bertram 31. Key to the continued popularity of the Bertram 31 on the used boat market is her legendary rough water sea keeping ability and her rugged construction. The last Bertram 31 was built in 1986, yet the iconic design remains popular and many continue to be refurbished.  The Double Deacon was completely restored in 2010 and re-powered with Yanmar diesels - just over 500 hours. Engines have just been serviced.

The boat was taken down to her bare hull and was re-wired and re-plumbed.  A new fuel tank was installed and she features a fiberglass cockpit deck and a transom fish box. Further, the Double Deacon features a custom teak interior, custom flybridge with single lever controls, and a diesel generator. She has air-conditioning and heat. She was fully painted and has a half-tower and hardtop.  Also, spray rails were added to her bottom and she is much drier than the traditional Bertram 31.

The Double Deacon is a must see!  Save yourself time and money - buy one that has already been refurbished.


The Bertram 31 went into production in 1961.  Over 2,000 31's were built in her two decades of production.  The Double Deacon is a flybridge cruiser model - meaning she has the cabin bulkhead aft and a stand-up head.

Known for their large and spacious cockpit, the Double Deacon has a highly functional cabin as well. Her diesel generator  provides for air-conditioning while on the water, along with other 120v systems on board.  

While known for their great sea-keeping ability, the Bertram 31 also has a reputation as being a wet boat.  However, the Double Deacon had spray rails added during her refurbishment and she is a much dryer Bertram 31!
