customer testimonials

We are excited to receive our first survey boat, a custom design from the ground up, being road transportable enables us to work in a lot more locations around the country, we already have projects waiting for it when it arrives, a big thanks to the team at PDL Marine for the can do approach and going back and forth until we got the perfect solution for our project requirements.

Custom New Build Road Transportable Survey Boat

PDL Marine's attention to detail and fit out is very good and I am extremely pleased with the finished product. She will join the stables of Bravo Lima and together make an excellent pair of professionally built, well thought-out and very durable craft.
