Instead of adding a screacher, why don't you find your crew another P16 and both of you sail solo? You'll find the P16 easy to handle, easy to right if capsized and MUCH, MUCH faster than with crew (especially 225!). You should be able to match or beat all but the best of Hobie 16 crews as well. More fun solo, too (crew = "Get off the jib blocks, you idiot!")
