Apologies everyone, sent that last message from the wrong account and it caused some confusion. Trying again!
I worked with this group 2 years ago and they are a VERY fun group. Be advised, no shoes are allowed on the boat (found this out the hard way after I arrived), plan accordingly with alternates for your footwear. Because only socks allowed (the pile of shoes is pretty impressive for this group). Ideas include using the overshoes that you sometimes see in cheaper suits (that go over regular shoes to make it look like you are wearing boots). Also I got a whee bit seasick last time, so those without good sea legs may want to pass on this one. They are usually sailing around Lake Washington, and every now and then some other boat will speed along causing a big wake and that rocks their very impressive vessel.
I am only sad that I am already booked at that time or else I would contact them.
