Operational history

In a review Michael McGoldrick wrote, "The Tanzer 10.5 (a 34 footer) was designed with a number of very interesting and innovative features. It has a retractable ballasted keel. Unlike many boats with a swing keel arrangement, the Tanzer 10.5's keel fills-in the entire keel house opening when it is in its lowered position. This means its performance should come very close to that of a true fixed keel. (While conceived as a boat with a retractable keel, it was possible to order it with a standard fin keel or fixed shoal draft keel.) Although the Tanzer 10.5 looks very much like a sleek sailboat, it actually has a pilot house with an interior steering station. Likewise, although the Tanzer 10.5 looks like it is an aft-cockpit boat, it is really a quasi mid-cockpit sailboat. It has a cabin located aft of the cockpit, which is connected to the main cabin by a small passage way. The innovative design of the Tanzer 10.5 does have a few drawbacks. For example, it has a small cockpit for a 34 footer, and because of the complexities of the keel lifting mechanism, this part of the boat is prone to problems."
