At a higher speed cavitation did increase slightly, due to the possible quick low-down torque from the 50 Yamahas. A few minor setting changes along with trim-and-tilts would help eliminate that. At higher speeds locking into turns, the boat held well on the water. Cutting around Vetch's Pier we were heading straight into the north-east chop and swell which had by now already jumped up to a 1.5-2m wind swell, with the odd white horses forming. I anticipated that we had a wet and bumpy ride coming up. Surprisingly, despite not being able to fine-tune the motors with trim-and-tilts to keep us dryer, the second pin setting was actually enough to keep the bow from scooping spray and splash. Comfort-wise, the T-Cat gave quite a soft, stable ride, into the swell and chop, at an approximate speed of 10-15 knots. Running the T-Cat side-on in the swell and chop, comfort and stability was good, even when a higher speed was being maintained. I also noticed that the splash and spray coming off the windward sponson, sprayed outwards and down, keeping the console area reasonably dry, and only spraying back onto the boat towards the stern. Turning and running with the dreaded north-easter was going to be interesting, as I would have to push the T-Cat in and out of the troughs. I was expecting a possible "nose-dive", since broaching and ploughing generally happens in these conditions. Tapping off on the drop into the trough and accelerating hard with the power of the 50hp Yummies eliminated any possible nose¬dives and broaches. Again, the ride was comfortable, stable, and dry considering the conditions.
The overall power and light weight of the T-Cat make beaching her a breeze. Returning through the shore break with a good, long slide onto the hard, dry sand was achieved with ease. |
