I am the Owner of Rafiki 37 Hull #1
We have circumnavagated with this boat.There were 55 made and most are on the west coast. They have more storage than 90% of 37 foot boats and have features that are comparable to most 40 footers. They are cored. They do not sail to windward very well, same as most gentlemen. However, they are a very strong and capable cruising boat. The age of these boats means that most have had at least one or two majoor re-fits. The boat you are looking at shoild have newer engine, new wiring, new stainless tanks, new wiring and all new mast, sails and rigging. If not expect to replace soon. They sail best with a monitor windvane. They have weather helm, and to reduce this you must shorten the main boom, increase mast height 5 feet, and add a bow spirit. They will average 100 miles per day in the trades, our daily best was 155 miles.
