Conch Cruisers
Read this first!  The information below is a compilation of suggested equipment that is recommended. How did we come up with this list?  Well, mostly through past experiences, times when we were caught saying, "I wish I had ___"  They are simply good ideas. To find the source of some of these ideas would require a proctologist with a flashlight.  Nonetheless, this is what works.
Now that the list is posted, you must realize that if you are the skipper of your boat, it is solely your responsibility to outfit your boat and take care of your crew. Do not be caught in a situation where you are saying, "I did not think I would need ______."  You may find that there are items left off of the list that you think need to go. Good. Take them with you.  Do not be caught short.
If you have any questions, put them on the forum. The odds are that someone else has the same question. If you want to e-mail me, feel free.
