k4man- If you never swam under the direction of a coach, some basic tips.
Learn the freestyle, stroke/breathe method. When you reach for a stroke/S-T--R---E--T---c-----hhhh every inch you get out of that pull is one you do not have to do on the next one.
Stay streamline, do not get sloppy with on your strokes with your arms all over the place like some eight year old running from a sea monster.
USe a TiGHT powerful Kick turn, you can gain several yards with every turn if you are tall.
You can get very good instruction at the Y - or you can look for a highschool (college) swim student looking to make $50.00 in a weekend... which as a matter of fact sounds like such a good idea I might see what is new in the compeition swimming world since 1987.
The local college is a nationally ranked team.. I am sure some of them need $$ for books (beer) and stuff.
