Re: [bolger] Re: Plywood Again???
- Pricing I've gotten for "signal MDO" is higher than Okoume ply. I'm sure
it's very good but regular MDO is where the savings is. There may be
voids to fill and it is heavy but I've had some outside for a year and
nothing is apparent. I sided my boat shed 3/8,10ft sheets but didn't get
around to painting, and it makes a not unattractive building with green
ondura roof. Clyde PS I think I mentioned earlier, that 8ft long, 10 ft
high wall sections are all I and a friend wanted to lift to stand up.

- That's exactly what I did. I don't know how thick their skins are; but If I
were in a position to order a boat build that way I'd insist on a filling of
the slots at leats with more foam.
I really don't claim or want to argue my point beyond the fact that I looked
at it in a very amateurish way; but decided I didn't trust this method; or
voids and gaps between skin sheets in a composite.
Now no matter how wrong I might be; I'm never going to be particular happy
in a boat that has this issue; so I avoid it.
