Bolger's Japanese Beach Cruiser

Phil Bolger's Japanese Beach Cruiser (JBC) is a 12.5' (3.8 m) seven panel sail boat.  

The JBC has a transom bow. Ross Lillistone's Whimbrel, Matt Layden's Sandflea and John Welsford's Scamp are three other examples of transom bow boats. Ross wrote a post about transom bows which incorporates some of Bolger's views. They make a case a for transom bows if there is a design constraint of LOA. 


The plans from Bolger's Boats with an Open Mind (pg. 127)


Using those plans, I built a 12:1 scale model pictured in the two photos below.

Specifications:

Length: 12.5' (3.8 m)
Beam: 5.5' (1.8 m)
Mainsail Sail Area: 89 Sq. Ft. (8.3 Sq. m)
Mizzen Sail Area: 24 Sq. Ft. (2.25 Sq. m)

The success of John Welsford's Scamp, which is similar to Bolger's Japanese Beach Cruiser, is a testimony to how successful a transom bow boat can be. Key is that we get a lot of boat for a short LOA.
