SeaWinds (and most RC
yachts) do not have any positive bouyancy. If enough water gets
into the hull the ballast at the bottom of the keel will pull the
boat under water and it will be gone in seconds, never to be seen
It's quite easy to
make your boat survive such an accident by adding bouyancy.
From the mast to the
bow there is a large void space inside the hull. If you work
carefully you can fill this space with Styrofoam. Get an empty
plastic bag of about 30cm. The bag that a loaf of bread comes in
will work well. It's very important to punch a lot of holes
through the bag with a pencil to allow any water that gets inside
it to drain out easily. Working through the hatch and around the
internal components, push the bag into the bow space. Then break
up some Styrofoam into grape-sized pieces and push them into the
plastic bag until it is filled and then close the neck of the bag
with a cable tie. The bag of Styrofoam will stay there for the
life of the boat and won't interfere with any of the functions of
the boat or its speed or balance.
The bag adds virtually
no weight to your boat but adds the peace of mind that if your
pride and joy gets flooded it will float stern down with its bow
facing up out of the water making it easier to see and be rescued.
