Admiralty charts are available for the larger lakes but they may not have been updated for many years. When meeting other craft, keep to your right. When overtaking other craft, leave them to your right. Remember, in strong flows, craft coming downstream must be moving quickly to maintain steerage so give them room. Remember also that large craft have a lot of momentum and may find it difficult or impossible to stop in these situations.
Power boats give way to sailing craft.
However, skippers of small sailing craft such as dinghies and sail-boards should not insist on this right unnecessarily as forcing a larger craft to alter course suddenly or make a crash stop may itself cause an accident. Give fisherfolk a wide berth at all times. In boats, they may be trolling with long lines and if fishing from the bank, your wake or engine noise may disturb the fishing, or worse, swamp them or their gear. Slow down in confined waters. High speed craft should slow down substantially when passing or meeting other craft or give them a wide berth.
