Just For Fun Watercraft Rental on Lake Travis in Austin, TX, has been Central Texas' best boat rentals company for over 30 years. We are Austin's original boat rental at Emerald Point Marina on the best part of the lake. Spend a day on a pontoon boat or party barge. Just For Fun created the original party barge, fitting up to 50 people for the best parties on the lake. We know the boat business. We are family owned and operated for over three decades. Our friendly, trained staff know how to create a memorable experience for you and your family. Our competitors' marketing strategy is to wait until we book all our boats - there's a reason we're the leader.
