Solid advice. I would add one thing - listen to Jules:
Use correct English in your ad. "Lose" is not equivalent to "loose."
"To" "too" and "two" all have different meanings. As do "there" "they're" and "their."
Frankly, if you can't be bothered to use decent grammar and have mispelled words in this day and age, it tells me that perhaps you are not the most detail oriented individual and that attitude likely carried over to other areas in your life - like boat maintenance.
