Hull Drain Plug – For Efficient Water Drainage During Planing

This genuine hull drain plug allows you to easily drain water from inside the ship while planing.
The ball inside the plug moves due to the inertial force of the hull, and the water pressure shifts the ball during acceleration and deceleration to prevent water from entering the ship.

Key Features:

  • Inertial Ball Movement: The ball moves based on hull movement to drain water effectively.
  • Prevents Water Intrusion: Water pressure moves the ball to prevent flooding during acceleration and deceleration.
  • Easy Drainage While Planing: The plug drains water as the vessel moves at speed.

Caution:

  • Do not stop the vessel for long periods.
    The plug relies on inertial force to drain water, which will not work when the vessel is stationary (e.g., anchored).

All around helpful---worth the money!
Format: Paperback
This guide has been most helpful for all the folks I help prepare for the iTEP test! It gives insight into what each section of the test is looking for along with examples and great tips about actually TAKING the test. In the Writing and Speaking sections, it also gives sample scores and comments from the Master Grader which is very helpful too.

Comprehensive, clear and coherent!
Format: Paperback
The iTEP Practice Guide combines a no-nonsense approach to the specific iTEP tests and at the same time offers exercises that task the student with what they need to know. Exercises not only serve the purpose of scoring well, but the overall approach is communicative competence. We use the text in our group and one-to-one classes with very positive--and lasting--results.
