Zipper is a 225 Class Hydroplane by John L Hacker.

This 18 footer was specifically design by Hacker as a racing craft.

It features all original sizes and dual cockpits. These plans are faithful to the original designs and using todays building methods should provide good speeds with added safety if built properly.

A building jig is also included in this design for ease of set-up.

All plans are full scale and in Adobe PDF format as a worldwide standard.
