Mr Steel Boat Brent is VERY fond of putting quotes from one theme forum's and single interest websites on here, as well as unsubstantiated claims, which, when challenged on, he cannot link to.
In that vein, a little story re GRP. Nicholson built a very good GRP yacht, the 32. They then built 26 55's.
Our Ministry of Defence purchased twelve for Adventurous Sail Training, giving our armed services the chance to experience sailing all around the world at modest cost. IIRC, all were delivered in the 1970's. They were made of GRP, designed by a good designer and built by craftsmen.
They gave superb service and no doubt a number cruncher could calculate the total mileage sailed by the fleet, but certainly more than most steel boats used by long term cruising liveaboards.
When they got tired-as all hard used boats do-replacement was considered. And rejected, as NOTHING available would fit the requirements, at any price.
So, they were re-fitted and continued in service. A couple might be still in service for all I know-a few years ago they were.
So, 40 years of being sailed on all Oceans, in all weathers by hairy arsed gung ho squaddies, airmen and matelots with a pro qualified skipper in charge. The boats were still in fair nick, still floating, untold thousands of sea miles under their keels. Not one sunk through hitting a container, another vessel or a whale while in this particularly arduous useage. I suspect another poster can add better info on the Nic 55's than me!
It really is an unsuitable material to build a boat from, isn't it?
Surely all 12 of them have been sunk after hitting a sandbar in mid-ocean or grounding on a coral reef and getting pounded in the surf.
