Let customers speak for us
from 719 reviewsGreat company!! New to boating and this is my go to place for good products.
Hoses seem to be much better quality than ones I’ve had in the past. Received the product in two days which was great.
Quick delivery and was just as advertised.
Looks like great products….. I can’t wait to put them on….. very fast shipping 😅
This is my second time purchasing from Captain's Preferred Products, and once again, I'm impressed! Their boat brush system is top-quality, extremely sturdy, and built to last. I also picked up their brush head organizer, which is a great addition for keeping everything neat, organized, and stored away.
If you're anything like me and love keeping your boat clean and looking its best, I highly recommend checking out their products. Definitely a great investment for any boat owner! Here's a video I did for my YouTube channel: https://www.youtube.com/watch?v=yWhq7nG5ogs
Easy to use website great selection and everything instock
Excellent quality timely delivery
The kit worked great. I used it as soon as we took the boat out of the water and it removed the "film" caused by the salt water and prepped it for waxing.
Good price, quick receipt of goods & reasonable freight fee.
I just received the order. Super excited to try the foam sprayer! I appears to be well made, sturdy and durable!!

Lost one too many fill cap openers... This little tool opens all my caps and serves as a bare bones multitool when I don't want to haul out the toolbox. Nice to have on the boat.
Thanks for the review! We agree - this is a must have tool to keep on any boat. Thank you for your business and feedback!
