1986 Silver Anniversary NY Boat Show edition Bertram 31 FBC

Excerpt from the Bertram 31 website;

Nothing in power boating has equaled the continued world wide popularity of the Bertram 31. One of several Bertram 31 models, more than 1,000 Flybridge Cruisers were built over the years. While they have been out of production for many years, used models are continually in demand regardless of age or condition.

Unquestionably, the chief attribute of any Bertram 31 is her legendary deep-V bull design. In addition to her superb sea keeping characteristics, the 31 FBC has a large fishing cockpit and comfortable (if Spartan) cabin accommodations with berths for four.

Regular production ended in 1983, but 23 "Silver Anniversary" models were built in 1986 with oak interiors and custom hull stripping. Twin 330-hp Mercruiser gas engines powered the majority of the Bertram 31s with several GM, Cat, or Cummins diesels offered as options. The Mercs would cruise around 23 knots with a top speed of 32+ knots.
Perhaps the best features of the 31 are it's low center of gravity, large cockpit, deep-v hull, and hard chine, all of which make this boat one of the best fishing platforms on the water today. It is obvious that the 31 is designed essentially as a fishing boat and creature comforts were considered as secondary considerations. The 31 also makes an excellent dive boat.
