Laser Stratos Fin keel
Last update: 3rd April 2020
The Laser Stratos is a 16’2” (4.94m) double handed sport keel boat designed by Phil Morrisson (United Kingdom). She was built between 1998 and 2008 by Laser Performance (United States). The Fin keel version features an L-shaped keel providing a good performance/price trade-off.
iThe CE design category indicates the ability to cope with certain weather conditions (the sailboat is designed for these conditions)
A: Wind < force 9, Waves < 10m B: Wind < force 8, Waves < 8m C: Wind < force 6, Waves < 4m D: Wind < force 4, Waves < 0,5m

Laser Stratos's performances
PY (Portsmouth Yardstick) rating
iPortsmouth Yardstick is an empirical rating system allowing small sailboats (dinghies included), of different sizes and designs, to race each other fairly. Therefore, by comparing these values, we can have an indication of the relative speed of 2 boats.
iDPN is a variation of Portsmouth Yardstick used in the United States.
Upwind sail area to displacement
iThe ratio sail area to displacement is obtained by dividing the sail area by the boat's displaced volume to the power two-thirds.
The ratio sail area to displacement can be used to compare the relative sail plan of different sailboats no matter what their size.
Upwind: under 18 the ratio indicates a cruise oriented sailboat with limited performances especially in light wind, while over 25 it indicates a fast sailboat.

iThe Ballast ratio is an indicator of stability; it is obtained by dividing the boat's displacement by the mass of the ballast. Since the stability depends also of the hull shapes and the position of the center of gravity, only the boats with similar ballast arrangements and hull shapes should be compared.
The higher the ballast ratio is, the greater is the stability.
