What causes my boat to porpoise?
What Causes Porpoising? Porpoising is the result of the motor’s outdrive pushing the boat upwards, essentially boosting it out of the water – albeit for a short period of time. This cycle will continue to repeat until either the boat’s speed is reduced or the trim is fixed.
Will a jackplate help with porpoising?
A jack plate does not help with porpoise, only somewhat makes it worse, but with the right prop and setup, it will work. Never had this issue with aluminum boats and motor and kicker mounted on transom, also most new glass boats now have stepped hulls, which is a jack plate in its self.
Will trim tabs stop porpoising?
Yes, trim tabs will knock down the porpoising issue and you can still adjust motor trim as well.
Are Contender Boats unsinkable?
Likelihood of a leak or sinking Review after review will confirm that the contender boats for sale are virtually unsinkable. The design is solid and even when there are cracks and bore holes in the wood, the vessels tend to hold up to the elements.
How do you fix a boat Porpoising?
Resolutions to an existing porpoising problem:
- Reduce Trim Angle.
- Change Static Weight Locations.
- Change Dynamic Forces location.
- Clean up Hull bottom condition.
- Optimize Propeller Selection.
- Design with Higher Deadrise (bottom surfaces)
- Trim Tabs.
How do you stop a boat from Porpoising?
Adjust Engine Trim Settings to Avoid Porpoising
- While the engine is in neutral, utilize the trim switch to tilt drive down all the way.
- Place the motor into forward gear and apply throttle until you reach cruising speed.
- Tilt the engine up with the trim switch.
Will a hydrofoil stop Porpoising?
Hydrofoils are the plates that bolt on your outboard cavitation plate, which increase the surface area of the plate. They work by lifting the boat out of the water as the boat gathers speed, creating less drag. Plus, they can stop a boat porpoising – i.e. bouncing up and down at high speeds.
Are Contender boats good?

Is it dangerous to ride a boat Porpoise?
The severity of boat porpoising can range from a mildly uncomfortable ride to downright dangerous, depending on the conditions. When the lift is generated at a high trim angle or low dead rise, it leads to an unstable load on all of the lifting surfaces. Plus, when boats porpoise, there are many dangers to consider.
How can I prevent my boat from porpoising?
Known as porpoising, this phenomenon typically occurs when a boat is traveling at a high rate of space with the incorrect trim setting. Normally, porpoising is prevented by making the necessary trim adjustments.
Why does the weight of a boat affect porpoising?
Altering the dead weights in your boat (fuel, battery, payloads, etc) can affect the speed and trim angle at which porpoising will initiate. Weight distribution changes can also have a positive effect on “where” the “hump zone” will occur.
What causes the hull of a ship to Porpoise?
A trigger to initiate porpoising – When a hull experiences a significant change in Dynamic balance of Forces, it will encounter some longitudinal instability, and if the hull is one that is already susceptible to porpoising at this velocity, then the dynamic instability usually triggers the onset of porpoising.
