Swimming in December

Wish I had a picture of this.  On the way in to Newport Beach, we ran through a patch of "something".  That "something" wrapped around our prop shaft, slowing us down and making noise.  We were able to get parked in a slip provided by the Harbor Patrol.  Yesterday I took the plunge in 64 degree water, found seaweed and a palm frond wrapped around the prop shaft.  I got that cut away. I then briefly inspected prop shaft (we need to replace the zincs)  the hull (good shape), cleared the knot meter, then got myself out of the water and into a hot shower.  I ended up with a few barks on my knuckles and knees from the barnacles, but no real harm done.
