Re: Purchased Boat Wanting More
I have not been on this site for some months because of a very busy travel schedule, but the thing I find interesting is a constant search for improved performance (not just speed) from the power boaters. The search includes everything from faster and easier time to plane, to correcting a list and eliminating porpoising. There are literally thousands of threads on these topics.
It is also interesting to note that most often trim tabs are viewed as a device to get the boat to plane faster, and or correct a list, and not any of the other benefits. This limited view is unfortunate because they do so much more.
There are two main aspects to overall boat performance, one is the engine and the other is largely ignored the boat hull shape.
Under the category of "engine" comes:
Horse power and type
Propellers (pitch, number of blades, stainless etc.)
Hydrofoils (since they mount to the motor)
Tilt and Trim
Under the category of Hull shape or design comes:
Design -For Skiing
Design - For Fishing (Expel: Bass Boats)
Design For - hauling loads (barge)
Design For - Cruising
Most often the focus for the improving boat performance is centered around the engine with specific focus on props, additional HP, tilt trim, transom wedge, and Hydrofoils.
This represents only 1/2 of the characteristics which dictate the overall boat performance.
The hull design is the other 1/2.
Trim tabs become an extension of the hull and change the design on demand. The results are exceptional. Buy putting a hook in the hull (deploying the tabs) when accelerating to plane the stern is lifted at nearly the same angle as the bow which eliminates the "HOLE" so there is No Hole Shot ( No hole - no Hole shot.) The boat accelerates nearly level. All of the energy previously used to climb up hill (hole shot) is now directed forward only.
Now you accelerate to plane with less throttle and less fuel - every time!
Once on plane you can adjust the hull shape (trim tabs) to maximize the hull performance in concert with the conditions that are occurring when they occur. Compensate for a list to port, weight balance, increase or decrease in speed, wind, waves, pay load, etc.
Focusing on both the hull and the engine creates a significantly better and more economical boating experience.
The hull dictates the performance of the boat more than the engine.
