Vico Plastics Clam Shell Vents
Vico Plastics Clam Shell Vents for Marine Ventilation
Vico Plastics approaches ventilation as an engineering problem. A boat sealed under a cover traps warm, moist air, and that humidity turns into condensation, mildew and musty odors that damage seats, carpet, vinyl and electronics. The company's vents are designed to let that air escape while keeping rain and snow out. This page covers Vico Plastics' offerings in clam shell vents.

The Boat Vent II
The product in this selection is the Boat Vent II (part BV2BLK), a black molded-plastic vent. It is built from durable, UV-protected molded plastic meant to withstand harsh sun, moisture and marine environments. Its compact, low-profile body measures roughly 4.5 inches wide, 4.5 inches deep and 2 inches high. It is also listed as made in the United States.
One practical advantage is how it fits into a cover. The Boat Vent II can be added to any custom or semi-custom marine cover, and it serves as the OEM replacement for commercial sewn covers made with vents. It also gives a support pole a dedicated seat. Compared with sew-in vents, it is intended to resist snow loads and heavy rain without letting the pole rip or tear the cover.
Why Vico's Design Approach Stands Out
Vico Plastics operates its marine line as Vico Marine. Vico Marine is a division of Vico Plastics in Janesville, Wisconsin, and has been a trusted name in the marine industry for more than 30 years. The company says it works directly with boat manufacturers, trim shops and canvas mills. That origin shows in the product's focus on professional fit and easy installation.
Water-shedding airflow is the central idea. Vico Marine vents use water-shedding airflow designs that block rain intrusion while letting trapped moisture escape. That is the job of any good clam shell vent: a hooded or shelled opening that sheds water yet keeps air moving.
What to Consider When Choosing a Cover Vent
- Intended use: The Boat Vent II is made for cover venting during storage, and is a different job from a hull or cabin vent.
- Pole compatibility: It works with Vico Marine boat cover support poles, sold separately, in several lengths.
- Installation: No special tools are required.
- Material durability: UV-inhibited polymers matter for any part left in sun, snow and rain for months.
