Hamlin and Butler Sailstar Boats 1964-1973? 278 sq. ft. portable 20 gal.

Approx. trailering wgt.: 5,750 lbs.

The A/C 25 was originally conceived in 1954 by Maine designers Cy Hamlin and E. Farnham Butler as a lightweight trailerable racer-cruiser, built using glued strip construction. The vessel became available from Sailstar Boats in fiberglass in 1964, with practically no change in layout, either on deck or below, from the wood version shown here. (No drawings of the fiberglass version are available.) She was available as a kit, semi-finished, or fully found and ready to sail. The A/C 25 was the most popular boat in the Controversy series of boats built in wood by E. Farnham Butler's Mt. Desert Yacht Yard in Maine; his boats ranged from 15 to 37 feet on deck. Best features: The "convertible doghouse" is a unique feature, enabling the main cabin to be bathed in sun and fresh air in good weather, and to be fully enclosed in canvas when the weather turns nasty. A well in the lazarette for an outboard engine installation will appeal to those who find inboard engines too hard to deal with. Worst features: Among her comps, the A/C 25 is the lightest boat with the least ballast and close to the highest SA/D ratio, indicating that she will be among the liveliest in light air, but with her relatively low Motion Index, will tend to be jumpy in a seaway. We recall spending some time on one of these boats with another couple, and we found it to be comfortable, light, and airy.
