I beleive there called fin extentions, I have a 20ft bow rider with a 140 mercruiser runs great, with 3 people on board and a lot gear I can get to 39 mph. How would these extensions make a difference, speed, stability? Any input would be great. thanks

That's about right for a boat of that size and power.

If you are asking what will a fin do? Well...... not much if it is not needed so save your money
