It s a laser radial.
Laser full rig optimum weight.
It was the first attempt at making a smaller.
The laser m rig is no longer in production.
A radial is 130 155lbs an the 4 7 is 105 125lbs.
A laser is an olympic class single handed boat.
The laser 4 7 uses a short pre bent lower mast to maintain a balanced helm and a sail area that is 35 smaller than the laser standard.
From what i remember optimal weight for a radial is 160 lbs while optimal weight for a full rig is 190 lbs.
It is ideal for learning to sail or for the lighter weight sailor graduating from optimist.
Range but club sailors do well weighing in over 200 lbs.
The target weight range for the full rig is very roughly 165 185 pounds.
The optimal weight for this rig is 110 145 lb 50 65 kg thus becoming an ideal boat for young sailors moving from the optimist rs tera who are still too light for a normal laser.
Full or standard rig used as the men s olympic class and designed for sailors 165 lbs 75 kg olympic sailors are in the 180 lbs.
In how the rigs are used remember the laser has three total spar pieces.
The different sail sizes roughly correspond to the weight of the sailor but can also be used to compensate for different wind conditions.
The hull weighs a mere 130lbs.
The international laser association recommend s the 4 7 for crew weights between 35 to 55 kg.
But the sail area on the full rig laser is so huge that you cannot successfully sail it if you weigh under 175lbs 175 being the minimum to sail this with any success.
The most apparent difference between a radial and full rig is the size.
The difference doesn t just stop at sail area though.
