Hi Joe,
Finding this an interesting, enjoyable, if somewhat rapid build to follow.
I'm working up ideas for a big (possibly twice size) quick build Springer style tug,
with enough grunt to push loaded barges or me in a canoe/punt around my local lake,
might try a split catamaran style hull to try and avoid the diving problem?
The ABS bulwark (an area where I struggle - trying to steam ply etc) is very interesting,
wondering what glue you have put your faith in to bond the plastic bulwark to the wooden (or varnished wooden) deck?
and how you formed the neat bends in the corners of the ABS bulwarks - possibly heated up around a dowel??
your method would save me hours of old school mucking about, turning SWMBO'S kitchen into a sauna etc !
Looking forward to more posts in the future. Paul
