A lightning flash can happen in half a second. In that instant, the lightning flash superheats the surrounding air to a temperature five times hotter than that on the surface of the sun. Nearby air expands and vibrates, forming sound that we hear as thunder. Sound travels more slowly than light, so it seems that thunder occurs later.
The cloud bottom carries a negative charge. Positive charges may collect on the ground, buildings, boat masts, people, flagpoles, mountaintops, or trees.
A stepped leader—a negative electrical charge made of zig-zagging segments, or steps—comes partway down from the cloud. The steps are invisible; each one is about 150 feet long.
When the stepped leader gets within 150 feet of a positive charge, a streamer (surge of positive electricity) rises to meet it. The leader and the streamer make a channel.
An electrical current from an object on the ground surges upward through the channel. It touches off a bright display called a return stroke

Depending on how tall and close the trees are, the chances are fairly low; lightning would probably strike a tree before the house boat. There's a chance for a secondary strike though.

Pretty slim. Lightning 'likes' (but doesn't always) tall objects - especially trees. At such a high voltage, trees are good conductors and in a likelihood, they will be hit first.
The reality is, unless that particular area is known for a disproportionate number of lightning strikes, you're probably very safe.

If you are around water, the probability is pretty high, however, if the elevation of the area is somewhat low, then the probability drops. Elevation, and enviornment are the two things that affect the probability of being struck by lightning.

Not sure of the question, but lighting will strike water and it will hit boats.
