630 Walkthrough

Blackdog Cats are the trailer boats with more safety features, more stability and more floor space than the others.

Innovatively designed twin aluminium pontoons provide an easier and safer way to enjoy the water. The interior has enough internal floor space for six people plus your food, dive gear and fishing gear.. Superior strength and stability mean the boat handles sea conditions like no other boat of its size.

The 630 Walkthrough allows you to use your whole boat, without compromising the interior space. 18 rod holders allow you to use it wisely.
