Industry recognized and a long time favorite of sailors! The model 747 Ultimate 12 Volt DC fan is recognized by Practical Sailor magazine as a “Best Buy” in the marine market. It features a patented FingerSafe blade that does not require a protective grill and has a shock-absorbing leading edge that flexes when it is stopped. The resulting maximum airflow makes the 747 Ultimate the top choice for sailors heading to hot, humid climates.
