A private charter is an option. We've chartered with Charlie many times and he is very reliable and knows the coast as well as anyone you will find. You can reach him at This will be quite an adventure for you. This is an open ocean trip in a panga so the weather can delay or cancel your trip. Really the only significant risk I can think of is being forced to cancel due to weather. Charlie can't refund your money because he can't sell the fuel and Euro is a years pay for many Nicaraguans. You'll have to send Charlie the payment in advance recommend Western Union so he can buy the fuel.
