Was looking at the Feb/March 2021 issue and on page 75 is an advertisement for BoatU.S. In the upper left quadrant is a picture of three tow boats, two of which are Shamrocks. A 20 ft Pilot House and a 26' Hardtop! These model boats haven't been produced for 25-30 years at least and are still workhorses today! Both are George Boynton (plus Nay and Richard S) boats. Couldn't find the picture online to link it but while looking noticed quite a few Shamrocks are still in service as tow boats. Makes me proud!
