It was very wise of you to ask those questions. Do not spend a dime until you take a formal boating course. You will then need to take the NH Safety Course
if you plan on boating up here in the lakes region. I say that only because the navigation on lakes is very different than on salt water, This fact is critical!
Many of our lakes are very rocky, Winny is one perfect example, and is not at all forgiving!
Renting a boat on any lake is fine but the boat needs to be returned exactly as delivered. If you hit a rock and damage the boat and/or lower unit in any way, you could expect to be charged for any and all damages. Most marinas do not offer insurance so beware.
