The Summer Twins 25 is arguably the model-which should have taken precedence over it's older cousin the Heavenly Twins 26, when the ST 25 design was Introduced. For all it's 25' length, the Summer Twins boasts at least 1.8m headroom throughout, three double berths, huge heads and great galley. With a wide beam she can take a good amount of sail area, and with good bridge deck clearance (no nacelle) and tiller steering she sails unusually well for a boat with this much accommodation!
