I'm pretty sure we couldn't hike a 400 hard enough for long enough and Chew is a fair sized lake.The handicap fleet is quite a mixed bag,including cherubs,fireballs.scorps, 200s,finns a few skiffs but not that many slow handicap boats other than wayfarer,byte, europe and we all start together, so things can get pretty strung out.The only two person fleet is the Flying Fifteens these days.

I think I'd be more likely to tip over in the Ent than the 400!
But horses for courses, who do you have to race against?

Foam sandwch is the key.
A solid GRP Ent which was down to weight would probably be fine racing against wooden ones of similar budget, when I was a lad, we raced a lot of Ents which were seriously overweight.
On flat water at club level, with half decent sails, it might embarass a few people in the right hands, same as a good sailor in something like a Vision can go way too quick for other people's comfort.

I have a good condition plastic Ent in the numbers 16,000 plus, it does not let a thimble full of water in, but I suppose their is bound to be one.

Fab100's list of Ent alternatives is uncannily like my own and I have owned or considered most of these.Lark:used to have one. I quite liked it but my wife/crew has a bit of a nasry,flappy Spinny phobia.ditto Scorp. N12 .I have had three, still got a Crusader. We're way too heavy for it at 24 stone combined and not really agile enough now at 107 years combined,most of that skewed towards me, and this also seems to apply to the Firefly,Grad and probably RS 200.The 400 is a lovely boat but too much of a beast,I fear.GP14? The decent non wood ones are pricey, just like the Ent and they are fiendishly heavy to lug up a slipway.I am not blindly loyal to Ents, but in the conditions that suit them they are still a thoroughly nice and rewarding boat to sail.

I concur that FRP is quite useless as a description.

To evaluate the material and likely capabilities you need to know
what resin system was used
what the predominant fibre type in the layup is
whether the shell is cored or not and what with

eg a modern Cherub or Moth would be epoxy carbon foam sandwich. The old Holt enterprises were polyester/csm/uncored. Between these two run a whole rainbow of construction methods with various pros and cons depending on the job in hand.

The basics are that if its uncored or coremat than its going to be heavier and weaker than plywood, and if its polyester then its going to go soft far far quicker than epoxy.

Think FRP was the late '80's
There certainly weren't any FRP GP's before they the Series 2 'revolution' with the double floor. Think Speeds built them. Though Don Marine did produce 1 or 2 GRP hulls with a double flood which I think they called the MkIV or V. There was in fact an Enterprise prototype produced about the same time with a double floor but it was refused by the CA. The Enterprise is a big class with a small rudder, ie change is very slow, and adoption of anything new takes an age. Having not sailed one for four years, and now sailing a Scorpion I was surprised at how big and lumbering one felt when I jumped in one a few weeks ago. Also compared to the Scorpion the hiking position is terrible. Esp with all the sharp deck parifernalia where the crew is meant to sit out. The GP is a bit more comfortable, only real issue is the weight. 124kg off the top of my head. Still recommend them to any new ish sailors that come to our club.

FRP = Fancy reinforced plastic, leaves scope for sandwich, carbon, Kevlar, boron, graphene etc.  

I think that many realise that the generic GRP largely refers to Bucket and Brush technology mainly using polyester resins, chopped strand mat and woven rovings (if you were lucky).  Boats like this are very strong but not very stiff.

Impossible to put an absolute time frame on the advent of FRP as we know it, since Bungy Taylor was building Finns in epoxy pre-preg in the 70's (going on to build Sauber f1 cars in a similar manner) and Ovi 14's in the early eighties.  And no doubt Jim will tell us that Skiffs were built with Nomex in the nineteenth century.

The Ent question is asked a lot on the Solo board, generally it is accepted that the Winder FRP boats were the step change in performance.
Happily living in the past

Time to move on. An MGB or Triumph Herald Vitesse may have been the best on offer in  1973 too, but were, like the Ent, soon eclipsed. The quality of those early grp Ents was akin to a  red-Robo Morris Marina Friday afternoon special.

At least GPs now have double-bottoms to go with kite, but also go try a Rooster Graduate, a Nat 12, a rs200 and 400,  a Lark, a scorpion,  even a firefly if balletic roll-tacks are your thang, before committing to Ent-brand-loyalty-above-rationality.

Personally, having sailed them all, I'd choose any of those before a good Ent, never mind a clunker Ent.
