I have a Seafarer 26 and my 'slip neighbor' has a Pearson 26.
See Sloanfiske's info. In addition to the skeg hung rudder and
encapsulated keel (no keel bolts to worry about) one major
enhancement the Seafarer has over the Pearson is where the
chainplates connect to the sidestays. The Pearson connects on
deck...eventually, unless you are maintenance meticulous, that
is where your soft spots will begin. The Seafarer's chainplates
are on the side of the boat...no soft spots or costly deck repair
Both are solid and neither will win a race...but I'd take the Seafarer26
over the Pearson26 every time.
