Its probably a small rowing boat. There are a few which are hired out during the summer from an area adjacent to where we sail. It is quite hilarious sometimes to watch the antics of people who haven't a clue how to row a boat
If you look just above that white dot and to the left, you will see a concrete landing stage (with a slipway alongside but not visible) - that is where we sail from.
A regular Sunday outing is to sail in convoy from there, along to the stream which you can see at the bottom of the photo and then as far again up the stream before returning.
In the opposite direction you will see a wooded area projecting out into the lake. This area contains some interconnected, very sheltered Lagoons.
A more adventurous trip which we sometimes do, involves sailing up to and through the lagoons, out into the lake again and round to the far side of the wooded area. Its a LONG way. A problem though is that we cannot get to the lakeside for all of the way and we can easily lose sight of the boats for a short while as they progress up the lake!
Its quite a trip and requires complete confidence in your model.
Do come to visit us, we happily let visitors sail a model or two.
Haven't seen a bobsleigh team practicing but we often see a long distance swimmer (towing a small yellow hi- vis buoy) going the full length of the lake,
