How do i make my seat be destroyed WITH my boat?

Currently when im testing in Studio, whenever i shoot at a test-boat to see how it destroys, the seat still continues to function perfectly fine even though everything around it is completely obliterated (i kinda made the power of my test-cannons a pretty high as well...the Force is about... 18,000,000... lol)

Here is the boat script i have:

seat = script.Parent

gyro = seat.BodyGyro

pos = seat.BodyPosition

vel = seat.BodyVelocity


pos.position = seat.Position

gyro.cframe = seat.CFrame

speed = 0

ready = true

wait()

seat.Anchored = false


function move(property)

if property == "Steer" then

	if not ready then

		return

	end

	ready = false

	steer = seat.Steer

	while steer ~= 0 do

		steer = seat.Steer

		if steer == 1 then

			gyro.cframe = gyro.cframe * CFrame.fromEulerAnglesXYZ(0,-.1,0)

		elseif steer == -1 then

			gyro.cframe = gyro.cframe * CFrame.fromEulerAnglesXYZ(0,.1,0)

		end

		wait()

		vel.velocity = seat.CFrame.lookVector * speed

	end

	ready = true

elseif property == "Throttle" then

	throttle = seat.Throttle

	while throttle ~= 0 do

		if throttle == 1 and speed < seat.MaxSpeed then

			speed = speed + 1

		elseif throttle == -1 and speed > 0 then

			speed = speed - 1

		end

		wait()

		vel.velocity = seat.CFrame.lookVector * speed

	end

end

end


seat.Changed:connect(move)

Group the Boat with your seat and then

seat.Parent:Destroy()
