Kevin, i'd have to say that most production boats would not be considered light.
, woven rovings, polyester resin and gelcoat
does not make a light boat in my opinion.
Light and go fast would be more a semi- production or an amateur build out of epoxy
resins and stitched fabrics, minimal bog and two pack paint
Just because a boat is production built is no gaurantee that is better made, quite the opposite in a lot of instances.
What makes a boat strong? Would a 4 x 2 hardwood beam be considered strong?
I was able to witness a "Drop Test" performed by a respected designer
and Dept. of transport reps. in relation to getting a composite laminate approved for survey
. I was there because I had made one of the test panels
As you are all probably aware solid fiberglass
construction has for years been considered to be the way to go and the survey
guys like it, but on this boat it would have actually made it dangerous due to the weight.
The test was at least 15 years ago, so my memory is not picture perfect, but I can remember my layup
4X2 hard wood was the benchmark just to see what happened when a 15kg weight with approx 90mm diameter is dropped down a tube from 2 meters.
The weight shattered the hardwood.
Next was my sample of 10mm western red cedar with 400gsm double bias glass either side using epoxy
The weight penetrated the top skin and left the other skin undamaged. Infact it took 2 more drops to compramise the other skin and another 2 to punch through.
This actually stood up better than some of the production builders panels
that were foam csm, woven rovins csm combinations. The glass on these was around 4mm thick with around 3mm of gelcoat
...... and heavy.
I honestly can't remember what the other panels were, but needless to say that the panel for the boat beeing built to survey got through with flying colours. It also was a Cedar core
boat with a triaxial glass and epoxy layup
, but more like 16mm and 1200gsm triaxial but not 100% sure.
Got to do a bit of research
on what i'd ultimetly want to be on in the big one, but i'm thinking not production as they seem to be built to a price
and a market, but at this stage i'd say a well built Simpson, Crowther , Tennant, Chamberlain or Schionning around the 40 + size
