Hi everybody.
Just wondering what the difference is (if any) between Fibreglass and Glass re-enforced plastic?
Are Norman boats a fibreglass boat or a G.R.P. boat or a combination of the two?
Thank you

Fibreglass or GRP , tupperware , splitter etc etc

"Fibreglass" - trade name for GRP which is Glass Reinforced Plastic.
Composition is glass fibres, laid random - CSM or chopped Strand Mat, wetted out with a polyester resin which hardens in the presence of a catalyst.
Gel Coat - a thickened, usually coloured, resin applied to a mould first to give a smooth finish, then overlaid with layers of resin and CSM.
In a large production the glass fibres are continuous, chopped and sprayed with the resin to speed things up.
Various other types of glass fibre cloth are used, woven in various ways, such as bi-axial, roving etc. Stiffness imparted by incorporating steel tube, timbers or even paper rope to form ribs or strengthening pieces. Weights are calculated in terms or grams per square meter, so you get 40gram, 60 gram, 80 gram mat and so on.
The cost of boating is insignificant compared to costs of a young wife and two teenage kids! |

Thanks for clearing that one up adi-n-chez and cliveshep. The old man was right again so! Are dad's always right or is it just mine?
Thanks again, I think I'll keep my mouth shut in future until after I've asked the question on the Norman Forum! |

Sorry, I dont mean this to sound 'fawning' but, its going to!
Is it just me in awe at the quality of answers that Cliveshep provides to a whole range of questions? Ive been meaning to ask this for a while following his in depth answerings to the lad rebuilding the norman 17 in Irelands questions. Thanks Clive I've learnt stuff I never new I was going to ask! |

I'll get conceited Ken but thank you very much for the compliment.
I have been a "boat-nut" from childhood - that's a long time ago now of course, and like many on here and on the DC forum where I also do quite a bit (have a look at their technical section) I had to learn to DIY and make-do-and-mend because money was always tight. Learning the how-to's came from asking a thousand questions, reading every book I could lay my hands on, haunting boatyards (I was a pest I suspect)and just trying. Being in Construction with a father who was a cabinet maker and joiner in his own youth helped no end, as did being allowed free rein in his workshop/garden shed as a child.
Like the Chinese journey of a thousand miles, it starts with a single step, followed by another, and another and so on. Those who are afraid to take that first step will never get to the end!
I'm still taking steps!

Fibreglass and G.R.P.-The same or different?
