Best advice you got so far was to weigh the boat to see if the foam is
waterlogged.

I don't know if you remember Jim, but I found out that my Ranger bay
boat is about 870 lbs over published weight putting the whole rig
right on the edge of trailer capacity - 4,980 lbs for a 5,000 lb
trailer.

The foam isn't waterlogged. I called Ranger about it and they didn't
have an explanation either.

I got to thinking about it. A gallon of water weighs 8 lbs. To have
870 lbs of extra water weight, the boat would have to hold 109 gals of
water.

That's a lot of cubic feet of water to have in foam on a 20 foot boat.

I've seen where some weigh their new boat and find it a couple hundred
pounds over. The manufacturers always claim it's because different
workers lay glass differently than others, especially in how much resin.
And that makes sense if you're talking 10% weight or so.

Funny you should mention that. Back when I was in the market for a
32' CC I thought about a custom designed CC from Blue Fin over in
Bristol, RI. We took a trip over there, met the design crew, took the
manufacturing plant tour (which was really interesting) and just
generally got comfortable with them - great folks by the way.

Anyhow, I asked about weight (because of the Ranger) and the design
guy told me the weight spec could be off as much as 10/12% to the plus
side and never on the other side. For exactly that reason - extra
layer of glass, little more mat in strength areas, density of the core
material and how it absorbed the resin under vacuum - he listed a
bunch of things that would cause the extra weight.

So you're right on that score.

Just as a side note, I would have bought the boat they planned for me
if the Grady dealer hadn't come up with an acceptable price. :)

I guess it suits my point which was if they are going to err, they will
always err on the lower side based on a perfectly constructed hull and
well.... Not really complaining, just sayin' that like buying a tent,
if it says it can comfortably ride 10, you can figure on a nice boat for
4-5
