If you have more than 12 people, you can choose to add a tandem boat to carry the extra guests and when stationary, the group can choose to be together on the main boat. In addition, sometimes it is possible for the tandem boat to offer water sports such as waterskiing, wakeboarding and other inflatables – an ideal solution and a lot of extra fun. This can be a cost effective option for groups 13 – 18 people.
