Thank you all. If I understand, HO211 divides the triangle into 2 right triangles. Is that the case with 208 as well? My regular cruising waters are the Great Lakes. Because of the proximity of shores, light pollution from Chicago etc., my initial choice was 229 over 249 as 229 appeared to offer more choice in body selection. There certainly is a case to me made for one small volume. My cruising grounds (Great Lakes) require two 229 volumes. Head south and I need a bookmobile to lug them all;-) With Lake Michigan boats now on the hard, and dinghy sailing/racing about done for the season, I hope to learn more about 208/211 when the snow flies.
