I’ve tested the Seacat 510 before, and as soon as I arrived at the Durban Ski-Boat Club I noticed some of the changes Yamaha have made to the craft. The first thing I spotted was that the gunnels have been lifted and some of her lines have been changed.
As with the whole Seacat range and all the boats that are manufactured by Grant Reed, the Seacat Blasts are of extremely high quality. Grant takes great pride in all the boats that he manufactures and on every boat test that I’ve done Grant has added his personal touch to it by accompanying us on the test to answer any questions that may arise.
Although the Seacat Blast 510 is essentially the same boat as the previous Seacat 510, she looks different and bigger when she is out on the trailer.
TRAILERING AND LAUNCHING
The Seacat Blast 510 FC and CC both fit on single-axle galvanised breakneck trailers — they are so light that you don’t need a double axle.
Getting the boats onto the beach was simple and without any hassle. We had a tractor to push them into the water, but I’m sure that with the help of boat pushers it would be very easy to launch her in the surf from the beach even without the tractor.
Loading her back onto the trailer is such an easy task that it could easily be done by one person, but two sets of hands make it that much easier.
MOTORS AND PERFORMANCE
The Seacat Blast 510 CC I tested was rigged with twin 40hp Yamaha 2-stroke motors, while the Blast 510 FC was fitted with two 60hp Yamaha 2-stroke motors. Although there is a vast difference between the 40hp and 60hp Yamaha motors, both these boats performed extremely well.
Both boats were fitted with side-mount controls and went into and out of gear very smoothly. From stationary they were also both very fast out the hole, although the forward console boat was a little faster because of the difference in horse power.
There were no signs of broaching when running with the swell and when I turned into the swell it seemed that the ride was smoother and softer than on most other boats. I could certainly feel the difference between the old Seacat and the Blast when I compared the ride of the boats as well as the speed at which they jumped on to the plane.
It seems that the wider pontoons allow the Blast craft to jump on the plane faster, even with one engine, and no doubt it’s the wider tunnel which makes the ride smoother. By making the tunnel wider and square, Grant has ensured that more water flows freely through the back.
With many of the cats on the market, it feels like you’re hitting a sandbank while travelling. This feeling is caused when a lot of water is forced into the tunnel and the tunnel is too small to allow the water to push out the back. This creates a lot of drag on the hull and makes the boat feel sluggish. Of course, it also pushes up your fuel bill.
With the new Seacat Blast 510 FC and CC the tunnels have been made wider which helps the front half of the boat to come down softly on the water. There’s also less spray out the sides because most of the water is being pushed through the tunnel.
