: in some places it
: looks like small ripples of glass with the peaks floating off of the wood
: and the troughs lying on the wood. No air bubbles, but the glass does not
: look like it is sitting flat on the woood.

I got this in a coule of places on my first boat. It was caused by over-
enthusiastic squeegeeing of the resin (perhaps I had let it cure a little
too long). As the squeegee is run down the glass, the weave gets stretched
in the direction of the pull, and will no longer lie flat.

: Is this a problem or will this "effect" be
: covered up with the fill coat that I am about to apply ?

Yes, it is a problem, the amount of fill coat required would be enormous.
However, it is not a problem you should worry much about, as it will only
be noticeable if you actually point it out to someone. Possibly if the waves are on the hull, and such as to cause extra friction, you might get a bit
of extra drag, or that part of the hull might be more susceptible to abrasion
during beach launches/landings.

: How could I try
: and avoid this in the future ?

I avoided it entirely on my second boat by doing very little squeegeeing
after the glass was wet out. There might be some weight penalty here, but
my second boat is lighter than the first, despite being longer, so I don't
think there was much penalty. I simply applied the resin with a brush and
made sure that the resin was moved along smartly after the glass was wet out.
I did a little gentle squeegeeing only where it was clear that a run was
starting. I got fewer runs than on the first boat, so my guess is that I
managed to wet out the glass using less resin in the first place.

If you feel that the ridges are going to be visible or add too much drag,
it would probably be best to remove the glass from that area, and then glass
it again, feathering the edges, as Nick's book describes for doing repairs.
But you may find that this is more visible than the original fault. I would
just live with it - its a good excuse to try to do better on your next boat :-)
