The F18 class is a much bigger boat, in length, volume, loads and rig size. It’s rules regarding build material also differ from the F16, so it is inaccurate to compare the skill / weights of building the two boats. More accurate to compare the F18 with the F18HT.
Steve,
Not sure i agree with you comments here.
F18 is 10% longer than F16
F18 has say 25% more volume than F16
F18 has 3-4% extra width over F16
F18 has 12% more mainsail area than F16
F18 has 10% more jib sail area than f16
F18 has 20% more spinn sail area than F16
F18 rig loads are thru rig loads only - crew weights are similar.
But they are over 50% heavier. That's comparing 107kg f16 to 180kg F18.
We all know that the manufacturers could build their boats at 165kg if they really wanted to, but profit margins reign.
Our F18 was well overbuilt & was over weight by 3-4 kgs. The new glass ones will be like the capricorn 5-10kgs under & weighted up to the 180kg max.
