Is this thickness what you'd class as substantial?

Is that a C flex lay up?

Our boat suffers a similar problem. The layup was, to put it mildly, excessive. We have an extra ton of resin and glass on top of the already generous original layup. That's a whole ton of pretty useless weight. A pity really, it just wasn't necessary, but the guy who had the hull built in '78 didn't trust this new-fangled fibreglass stuff.
Still, provided it was laid up properly you won't lose a lot of sleep over osmosis.  And most other boats will bounce off you without leaving a mark.

P.S. Any chance of posting a bigger picture? I am seeing a lot of colour variation on the layers there. I am no expert, but that is a bit odd, and may indicate layup issues. I've never seen such colour variation before.

Not sure Cadence, but I hope so, C-Flex I've learnt is very,very Strong,
being a 1978 built hull its quite possible as I read it was used quite abit in that era...

The plug looks as if it is C flex. You can see it with glass laminated on both sides. One good product for a one off hull. Just to put it in prospective what was the dia. of the plug?

I don't know, I will ask the Owner, he has the plug, thinking it was where
a Raw water skin fitting for the 50hp Yanmar was installed, if that helps.

If it is like ours, that was right on the curve from the hull to the keel. From Minaret's response it sounds like that keel is going to stay nicely attached.

Re: Motor Sailor or Sailboat?
Hi,
I'm new to the forum and am about to ask opinions on the age old question: Does a motorsailor sail okay? I am about to buy a Cheoy lee 53 motorsailor and I have sailed on one before. Much to my surprise they sail remarkably well. They are no Mumm 30 but they point and reach quite well. The added bonus of 2 motors (allthough twice the maint) and a 3200 litre fuel carrying capacity. My only concern is they are a bit of a dog downhill. Otherwise I think they make a great bluewater passage maker. Any comments?
