ur
• Currently working with Yella Dog guide
service in order to make economic
improvements
• Yella Dog is limited to ferrying (“1”) shuttle of
clients consisting of (“4”) persons daily.
• By raising the operational speed of the
watercraft the customer will be able to run
(“2”) shuttles daily, essentially doubling
revenue. The potential increase in revenue
throughout the season has been estimated at
$40,000.
• $5000 Budget
• End-of Project Deliverable a boat and motor
capable of traveling at 30mph carrying 800lbs
