Thanks everyone for all your comments and suggestions so far. I think the most daunting part for me is the locks as there are a lot of GRP boats that tie up near the entrances when its busy and I am conscious that its not easy to avoid collision in such close quarters if you haven't got it right first time ! At 15 tons ( unloaded ) I would not want to hit one --or graze past it. ! On the open river its a lot easier , except in high Summer when there are paddle boards, canoes and wild swimmers to try and avoid ( I plan to make most of my trips outside of the peak season )
I think that having a "flat bottom " ( if you will pardon the phrase ! ) makes it a little less easy to turn than the standard v-shaped hull and I am having to get used to the fact that it takes a short while before the bow starts to turn ( by which time you have probably oversteered and need to correct again ! ) I have learned that when turning her around a bit of reverse thrust at the halfway point will swing the back around and tighten the turn ( at the moment I always feel that I am closer to other boats than I actually am )
My instructor was very good and we used the method of counting the turns from full lock left to full lock right ( about 5 of them so hard to really get a precise "straight ahead " guess )
The only other thing that my instructor was very good at was telling me all the things that could go wrong, which while very helpful did not help to ease my nerves !
Due to Covid we were late launching ( late July/ early August ) so I am really hoping to make the most of things once the days get a bit longer again.
My main point really is ----how long do you think it will take for me to get a bit more proficient ? In terms of engine hours, how long did it take you all ?
