How can I make this boat have a max speed?

local re = game.ReplicatedStorage:WaitForChild("re")
local boat = script.Parent
local bounce = false


function goForward(move, speed)
	move.Parent = boat.basepart1
	move.MaxForce = Vector3.new(math.huge,0,math.huge)
	move.Velocity = speed
	boat.basepart1.Velocity = speed
	boat.stats.acceleration.Value = 1
	bounce = true
	while boat.stats.forward.Value == true do
		wait(0.5)
		move.Velocity = boat.basepart1.CFrame.lookVector*(move.Velocity.magnitude+boat.stats.acceleration.Value)
		if boat.stats.acceleration.Value <= 4.6 and boat.basepart1.Velocity.magnitude < 36 then
			boat.stats.acceleration.Value = boat.stats.acceleration.Value + 0.3
		end
	end
	bounce = false
	boat.stats.acceleration.Value = 1
	while boat.stats.forward.Value == false and boat.basepart1.Velocity.magnitude > 2.9 do
		wait(0.5)
		print(boat.basepart1.Velocity.magnitude," ",boat.stats.acceleration.Value)
		move.Velocity = move.Velocity - Vector3.new(boat.basepart1.CFrame.lookVector.x, 0, boat.basepart1.CFrame.lookVector.z)*boat.stats.acceleration.Value
		if boat.stats.acceleration.Value <=5 then
			boat.stats.acceleration.Value = boat.stats.acceleration.Value + 1
		end
	end
	if boat.basepart1.Velocity.magnitude < 4.6 then
	move.Velocity = Vector3.new(0,0,0)
	end
end


function turn(move, direction)
	if direction == "a" then
		while direction == "a" and boat.stats.turning.Value == true do
			wait()
			boat:SetPrimaryPartCFrame(boat.PrimaryPart.CFrame * CFrame.Angles(0,0.004,0))
		end
	elseif direction == "d" then
		while direction == "d" and boat.stats.turning.Value == true do
			wait()
			boat:SetPrimaryPartCFrame(boat.PrimaryPart.CFrame * CFrame.Angles(0,-0.004,0))
		end		
	end
end

re.OnServerEvent:connect(function(player, input, stroke)
	if boat.stats.driver.Value == "" then
		boat.stats.driver.Value = tostring(player)
	end
	if (tostring(player)) == boat.stats.driver.Value then
		if input and stroke then
			if input == "w" and stroke == "press" and bounce == false then
				bounce = true
				boat.stats.lastSpeed.Value = boat.basepart1.BodyVelocity.Velocity
				boat.stats.forward.Value = true
				goForward(boat.basepart1.BodyVelocity, boat.basepart1.BodyVelocity.Velocity)
			elseif input == "w" and stroke == "release" then
				boat.stats.lastSpeed.Value = boat.basepart1.BodyVelocity.Velocity
				boat.stats.forward.Value = false
			elseif input == "a" and stroke == "press" then
				boat.stats.turning.Value = true
				turn(boat.basepart1.turn, "a")
			elseif input == "d" and stroke == "press" then
				boat.stats.turning.Value = true
				turn(boat.basepart1.turn, "d")
			elseif input == "a" and stroke == "release" then
				boat.stats.turning.Value = false
				--stopTurn(boat.basepart1.turn)
			elseif input == "d" and stroke == "release" then
				boat.stats.turning.Value = false
				--stopTurn(boat.basepart1.turn)
			end
		end
	end
end)

You really only need to focus on the goForward function, since that's what makes the boat move forward. I've got it so that you can turn the boat and it will move in the direction that it's turning, and I also have acceleration and de-acceleration down. However, I just can't seem to figure out a way to make this boat have a max speed. I want it so that the boat cannot go over a certain speed. Can anyone help me out?

Set your own maximum speed, rather than setting Positive Infinity as maximum speed .

 move.MaxForce = Vector3.new(UR MAXIMUM SPEED,0,UR MAXIMUM SPEED)
