Suitability of a Laser dinghy for learning
If you are not interested in competing and racing then why are you looking to buy a "race-car" dinghy?
Lasers are not comfortable, adaptable to various conditions or versatile in their uses. They are stricktly and simply a one-design-racer.
Why not find something that has some comfort and lets you maybe drop a fishing line over the side or get good enough that you can steer with one foot and read a novel as you scoot across the bay (glancing up to make sure you are not about to smack into a ship, of course).
You can take any "old tub" dinghy and work and concentrate really hard at yanking every last erg of speed and performance out of it when you are feeling in the mood (and this is satisgying as long as you are competing against no-one but yourself and your past times across a certain distance/conditions. But in laser you will never have the option of NOT being fully keyed up and aware and struggling for every last erg of performance...or the boat will dump you out on your bruised and waterlogged butt. A laser does not offer the option of "relaxation" until after you have loaded it back on its trailer and are towing it home.
Great if you have the competitive urge and want to do club racing or something...but if that is not your thing, then why punish yourself with a dedicated race sled?
