the Hydrofoil may help a little, but any 13 foot whaler will have issues getting on plane with more than 2-3 adults on board. The weight capacity plate is for how much weight the boat can handle not how much weight the boat can perform well carrying. If you want to carry 4 or more adults than buy a bigger Whaler. Mt 15 foot Dauntless with a 70 H.P will perform well with 4 aboard even though the capacity plate say the boat will hold 6 people.
