Re: Just look at the

I have worked on Trawlers where you can see the sea through the glass fibre. It has nothing to do with thickness, it is due to colour of gel coat and types of materials used. Trust me, these boats were a lot stronger than any yachts built of GRP.

Excepting of course super yachts (before some bright spark jumps in)

Yes you can see through

the GRP hull!!

It sounds daft that boat hulls can be so thin that you can see the waves moving up and down outside the hull but its true.

Just look at any modern GRP boat and you will be surprised when looking out from inside at how much is visible - especially on the sunny side.

Re: Yes you can see through

If the glass has been properly wetted by the resin then the resultant GRP is translucent. Get more worried if the GRP is white and you can't see through it; that often means that there are air bubbles resulting from inadequate wetting.
 
Re: Yes you can see through

I shall have to look more carefully. Never seen this effect in any of the boats I've been on.

Re: What happened

I heard something else today, from someone who saw the incident. They gave this report to the police....

As well as the doughnut thingy on the coach roof obscuring the helmsman's view he had thought ahead. He had sat two of his crew on either side of said doughnut to stop it flipping up in the wind. As he left the entrance to Pwllheli he pushed the throttles to full power and both these people were thrown overboard, seconds before collision.

This is probably why there were no human casualties. There is no amount of training in the world that will stop negligence like this, I hope they throw the book at him.

Re: Correction

Although it is an older boat, closer inspection of the layup, which is now exposed, shows somewhat dubious construction. The gel coat is about 2mm thick, and behind this the layup is entirely CSM. Much of the interior CSM is completely dry, it looks like it received no resin at all. There does not appear to be even a single layer of roving.

I doubt many boats are made like this now, CSM is considerably weaker than roving, and without resin has no strength at all.

Re: Correction

I remember, many years ago (early 1970's) when I was working at the Earl's Court Boat Show, having a sneaky look at the boat that was bombed by the IRA with my old man (who is a surveyor).

The bomb blew out part of the side of the boat, exposing the lay-up, and revealing the same thing - ie lots of dry matting on the inside. Obviously a '70's thing along with loon pants and bad acid /forums/images/icons/laugh.gif
