Ronan Donovan contributed this list of what you should bring to practice. Thanks, Ronan.

Sailing Packing List:

Lifejacket
Helmet
Swimsuit
Water Shoes
Water Bottle
Sunglasses
Rash-shirt
Sunscreen
Whistle
Bailer
Sailing Gloves

I would note a few things:

(1)  REI lists a whitewater helmet for under $30.00 that would be suitable.
(2)  They have a nice compact life jacket for about $100.00. Please pick a bright color.
(3)  Get “croakies” for your sunglasses or some type that stay with you.
(4)  Attach your whistle to your life jacket with a lanyard.
(5)  You can make a suitable bailer by cutting the top off of a plastic bleach or detergent bottle, keep the handle intact so you can “scoop” water out of your boat.
