"And on another
matter, I was reading in Cruising Helmsman magazine about looking out for
floating submerged logs around PNG/Indo.
This would be a worry on harrys. Perhaps an extra foot of bow that angles up to take the hit and ride up over the top of the log?"

In the PNW (USA) and in the big channels and
rivers everywhere it seems that submerged logs are a
problem. You hear of boats hitting logs squarely, riding over,
and losing daggerboard or rudder or prop or
everything.
So is an angled bow an advantage or
maybe not? And how much of that depends on the angle of the
log?
I've hit a few logs myself and most of the
time the boat moves over a little and the log also moves over and what you
have is just a sudden stop and big scrapes down the sides of the hull.
The sudden stop can be worse than the scrapes. The only time I had any damage
other than scrapes was when I hit a log almost squarely while motoring in
my small tri and it took off the prop and bent the shaft as we rode over.
My own preference is for a straight bow with the
forward foot or two being made to crush and easily replaced. That puts the
actual structural hull a foot or two behind the crush bow.
Obviously there's an advantage
if pieces protruding beneath the hull are able to pivot. If that
can't happen, I'd prefer things to break away cleanly in a manner of
my choosing. Makes repairs easier.
