How To Install Boat Hatch Actuator

Boat Hatches: What Actuator Should You Use

Installed WindyNation actuators on my Taylor SS jet boat’s motor hatch with custom override system

Boat hatch actuators serve a critical role on marine vessels as they keep the environment from reaching sensitive areas, be it the living quarters or mechanical and electronic equipment. These hatches tend to be heavy due to the nature of their function and as such, it is often difficult to open them by hand when required, especially in choppy waters. This article will explore how to automate the boat hatch with a linear actuator and what factors you should consider when making your actuator purchase decision, ensuring quick and easy access to any area on the boat that is separated by a hatch.

Special Relay For Engine Hatch Actuator

chuckyarusMy engine hatch actuator has never been strong enough to get the hatch up in the closed position. I ran wires straight off one battery with me in the engine bay with the hatch shut and it went right up with no problem. So how can I get the voltage up with the factory switch? I don’t see how I can a relay up because the positive and negitive wire is going to switch back in forth depending on which way you work the switch. I don’t really want one switch to go up and one to go down. Is there a special relay for this?

    Super Lift Electro Mechanical Linear Hatch Actuator

    Hardin Marine’s Super lift Hatch Actuators use a time proven design while blending significant construction and performance advantages These units use severe duty 12V DC motors to provide a 20% faster actuation than the competitors Each of these units uses a beautifully polished stainless and black coating offering a stunning appearance with supreme corrosion resistance With a 400 LB maximum load capacity you can be assured your getting the best you can buy.”

    Notes:

    • A 30 amp, type AGC fuse must be installed between the power source and actuator switch to protect against overcurrent.
    • Actuator “on time” must not exceed 25%. Example: If “on time” is 25 seconds, then the actuator must remain off for 75 seconds before being operated again. Exceeding a 25% duty cycle can lead to overheating and may result in hazardous conditions.
    • Actuator is factory lubricated for life and no additional lubrication is required for maintenance.
    • The actuator incorporates a slip clutch to protect against overloading. The clutch is preset at the factory to slip if the load exceeds the rated load.

    *Static loading refers to the load on an actuator when it is in a fixed or stationary condition. The static load capacity of an actuator refers to how much weight the actuator can safely hold without back driving or causing damage.Dynamic load is the load the actuator sees when it is powered and extending or retracting. The dynamic load capacity of an actuator refers to how much the actuator can push or pull. Placing an actuator closer to the hatch hinge point will require the actuator to work harder than installing it further out.

    Calculating The Force Of The Actuator

    Once all the above factors have been determined, the force of the actuator for your boat hatch can be estimated. In order to determine what size actuator is required, the maximum force must be calculated. This can be done by drawing a simple free body diagram to visualize all the forces acting on the actuator.

    To simplify the calculation, only the worst-case scenario is considered, i.e. when the hatch is in its closed position. This is because as the hatch opens, its weight is increasingly taken up by the hinge and therefore the actuator requires less force to push the hatch open.

    Assuming the door is in the closed position the actuator force Fc can be determined by calculating the moments around point B. The free-body diagram for the closed hatch position is shown below.

    Simplified the y-component of the actuator force is equal to the weight of the lid multiplied by the length ratio between the applied force and the gravitational force.

    In order to calculate the required actuator force, Fc, the y-component and angle, theta, must be used as per the force triangle below.

    The equation for Fc below can be used to determine the actuator force required to open a boat hatch with an initial angle theta and mounting location of L1.

    For a more in-depth analysis on calculating the actuator force, follow the link.

    From Back Breaking To Back Saving: Actuators

    Engine hatches are inherently heavy and awkward to handle while the boat is on the trailer let alone on rough water. So any knowledgeable boater will tell you that if you dont have one, installing a hatch actuator will be the smartest, easiest, and one of best bank-for-your-buck upgrades;you can make to your boat.

    There are two factors involved when picking out an actuator. What size do you need to accommodate the weight of your engine hatch? And what type of actuator is best suited for your needs.

    Hardin Marine is where we found several high quality actuators which can be found here. With various options you need to first determine what kind of actuator you need. There are electric, mechanical, pneumatic, and hydraulic actuators, all with their different advantages and disadvantages.

    Electric actuators use an electric motor that can be either internally or externally connected to the unit. These are the most popular because they are easy to install and dont require oil or gas, making them cleaner than other options. However, they tend to be less powerful than the other options so take that into account before choosing.

    Mechanical actuators operate similar to electric actuators except that they use gears, screws, and chains, etc, resulting in more power and higher torque.

    So if youre in the market, take the time to assess your needs and choose the right actuator for you! And let the great team and Hardin Marine help you through the process today!

Kept it maintained, but broke internally. My first choice for a replacement was from CP Performance part# 620-920018 for $223.99, but was backordered. Not wanting to wait, I purchased a Livorsi HA18 which is a little nicer and colors to match the boat for around $280 + shipping. Used existing mounting hardware and it works great and fast, even with existing wiring on a 2001 380 Avenger. Hope this helps.
