I complained about 'heavy helm' when I first bought my Seal 28. I expect my postings are in the 'old' forum, still. After a while I found the trick is to pay particular attention to the course. Don't let the boat wander off course. Make course corrections with very small movements (steer small, as Hornblower would have it). In fact, I had to re-learn how to steer! You have to train yourself to do this, while doing all the other tasks required, such as playing the sheets, looking out, waving at motorboats, etc. That is why the autohelm manages OK - it is doing only one job and concentrating on it. You will find that you can learn to do this and fairly soon, you will learn how to do it by feel and suddenly, the helm won't be heavy any more - it will just be very sensitive and powerful. Its a bit like a learner driver finding the throttle pedal too sensitive and kangaroo-ing down the road on his first go. My theory is that the Seal 28 does not have much directional stability, so left to herself she will very quickly veer off course. If you let this happen, you have to fight the momentum of the turning boat to get back to the course you should be on. There are occasions when this lack of directional stability is helpful - you can make very tight turns (useful in marinas) and you can also use it as a brake. If you want to stop in a hurry, do a tight 90 degree turn - you can easily lose 5 knots. I use it to pick up the mooring while under sail - approach down wind, pass the buoy at about 10 metres distance, when it is level with the cockpit, jam the helm over. The boat will pivot on her keel through 180 degrees and stop dead with the buoy just under the bow!
Give her another chance! Neil
