1986 Dickerson 37

Hingham, Massachusetts


There's little not to like about the Dickerson 37.  She's well built, gorgeous to look at, roomy and attractive below, and she sails beautifully.  Her modified full keel with skeg-hung rudder helps make her well-mannered under sail, and her 4' 6" draft allows her to get places other boats are unable to go.

SIENA has had excellent care. Recent upgrades include rewiring, new electronics, and a fuel polishing system that runs whenever the engine is running. Her exterior teak has been nicely varnished.

SIENA is equally comfortable as a family cruiser or trophy collector.  In 2018 she earned the huge distinction of winning Division D and overall winner of the FIGAWI race from Hyannis, MA to Nantucket.

The owners' growing family has has decided to switch to power for awhile.  Here is a tremendous opportunity to acquire a desirable boat.  She's been priced to sell and is currently stored at her owner's house in Hingham, MA, covered with a custom winter cover, but easily seen.

 Owner notes: "I've done a lot of work to this engine. Inherited a few issues which have now been rectified and engine runs perfectly. Idles and runs with zero issues, no smoke, no bad behavior. I could talk about what I have done with this engine for a week. Engine room is very clean and thoughtfully laid out. This isn't one of those nightmare engine rooms where everything is rusty and hasn't seen light of day. I appreciate a clean engine space, new hose clamps, everything loomed, chafe free, no drips or weirdness going on here. I am very particular about how things are maintained."
