Hi Mark,

I have made a home-made sea achor that
works pretty well - if not perfect -
I'll do it better next time!

I started by using a home made drag chute 
(which I had made for my little model 
airplane winch) that I attached to a ring 
(some toy that you've supposed to throw like
frisbee). At the top of the ring I attached
a little float of styrofoam, or EPP, and at
the bottom of the ring I attached a little weight
(a huge washer), so that it would sink propperly 
when launched.

The problem is that the chute is a little bigger than
the ring, so it isn't a perfect fit (see photo
- taken today so the chute a little wrinkled:

The drag chute I had made from ripstop nylon,
four triangular pieces with their tops cut of,
so that the chute in reality was a pyramid
with the top cut off.  The top must be open or
you'll have an unstable design! 

Kite shops sometimes sell small drag chutes 
to be used with parafoils!

A four-line bridle I used, but a three-line would 
work as well - I reused the one that I had made
for winch use (no plastic ring then, as in the air
it opens very well by itself, not that easy in water!).

Another possibility would be a defunct umbrella -
save the fabric, make a big centre hole, and adjust the
size to the ring you find!

I'll change the ring in a few days time, to one properly sized - using
a similar toy called Aerobie Pro - bought in the kite shop in Seattle!
