You will definitely be happier with the 303. Its a bit more 'robust' than the previous Pearson-Shaw designs and not subject to 'hull-flex' as are the P26 and P30.
That stated, its REAL important when blocking any Pearson that the jack stands are ON the bulkheads (put a mark on the waterline so the travel lift operator doesnt have to 'guess') and more importantly that AFT end of the keel is NOT blocked!!!! Only TWO blocks go under the keel when blocking - one at the front of the keel and the second placed directly and vertically
below where the aft of the keel joins the hull. If you put a block under the extreme aft end of just about any Pearson keel ... you will get grotesque hull distortion!
Good Luck and enjoy your fine PEARSON !!!
