Adventure Island bowsprit

IMHO, a bowsprit is one of 3 crucial mods that are needed get the most out of
a jib (or any other head sail) on a Hobie Adventure Island (AI) or Tandem Island (TI).
Of these 3 mods (the other 2 being a mast topper and a rigid "mast" for the jib),
the bowsprit is the most challenging to construct. Here are some details on
my latest version.

First, a couple of pictures of a broken bowsprit, where you can see how
it was attached.

Btw, this did not break under normal use. Instead, it broke when the boat
accidentally slid off the trailer, and the bowsprit hit
the edge of the trailer, taking the entire weight of the fully-loaded boat.

Here is my new bowsprit. Previously, I've always made these out of a single piece
of 1.25" PVC pipe, but for this one, I inserted 1" PVC inside the 1.25" pipe,
which should make it much stronger. Of course, it is a bit heavier, and it could
conceivable be "too strong", in the sense of causing some other part of the
boat to fail in an accident. I'd certainly prefer that the bowsprit break,
rather than some other part that would be far more expensive to repair.
I don't think this will be an issue, but it is not inconceivable.

Closeups showing the various dimensions.

Perhaps the trickiest part is the frontmost connection. Here, I used a large-sized
stainless "rope loop" from Home Depot and bent it to fit. This larger loop makes it
possible to center the 1/4" diameter cross-bolt that passes through the loop,
connecting the loop to the PVC pipe. You can compare this to the closeup
of the broken bowsprit in the first post in this thread, which used a
standard stainless pad eye. That standard pad eye necessitated that the cross-bolt
be much lower, which makes for a weaker spot where the bolt passes through the PCV.

The final result, and a picture of the complete setup.

Looks great! You're really getting the sail rigging dialed!
