I would like to buy a Laser Radial to sail in the the Caribbean, where the winds in the winter are most often 8-15 MPH. I'm an experienced centerboard sailor and recreational racer, about 60 years old, and am concerned that the Laser Radial would be too much work just to keep upright when day sailing, although I would like to do a little racing as well. I have two questions: 1) How would you describe the difference between the Standard Laser and the Radial regarding how tender and difficult it is to sail in 8-15 MPH? 2) Would it be possible to put a 4.7 sail on a Radial rig just for daysailing in higher winds? Any help would be appreciated P.S. I am 5'8" and weigh 165 lbs.
