As those familiar with the East River Community know, our roots can be traced back to the Mowry Bay Yacht Club and the Second Life sailing community. Thus, navigability of the Second Life waterways is a natural concern to us. For this reason, some of us founded the Open Seas Project (OSP) group a couple of years ago.

Quoting from the group charter: Nautical activities in Second Life are getting increasingly difficult due to the many residents who use ban lines over waterways. The purpose of the OSP is inform and educate these residents on how to minimize the effect ban lines have on nautical activities and to encourage them about keeping waterways navigable.

Dear land owner,

this notecard is sent to you on behalf of the Open Seas Project by one of our volunteers because your property apparently overlap a waterway and something is blocking the passage of boats. Please read some important information.

Nautical activities in Second Life are getting increasingly difficult due to the many residents who block waterways with ban lines and other obstacles. The purpose of the Open Seas Project is to inform and educate these residents on how to minimize the impact of these obstacles and to encourage them on keeping waterways navigable.

If this note was mistakenly delivered to you please accept our apologies and ignore this message. If you are not the owner of the land you may want to deliver this note yourself or contact one of the group volunteers so that this is delivered to the right person.

How you can help keeping waterways in Second Life navigable


  1. Ban lines are the most troublesome obstacles on waterways. Not only they block the way, they often cause crashes and other nasty effects. When turning ban lines on, take into serious consideration that you may be blocking all nautical traffic. Consider this: do you really need a ban line on your property?
  2. If you do need a ban line, there are ways to limit the effect on navigation. The best thing to do is to split your property into two parcels, where the new parcel is the part of your property overlapping the waterway. Once split, keep the ban lines turned on where you need them and turn them off on the parcel overlapping the waterway. Splitting parcels will not affect your property or your prim allowance.
  3. When building on waterways, make sure to leave enough space for boats to pass by. When building a bridge, consider that some boats have masts several meters high. Some motor yachts have considerable sizes. While it would not be possible to accommodate the need of any boat in Second Life, use your best judgment on leaving enough space for boats. If you need advice you can contact an Open Seas Project volunteer, the Second Life Coast Guard (SLCG) group or one of the yacht clubs in Second Life.
  4. Make sure that the parcel overlapping the waterway has “Object Entry” and “Run Scripts” options enabled. If you don’t, boats will not be able to enter the parcel or operate properly. If you don’t want to enable these options on your property, consider point #2 to create a separate parcel where these options are enabled.
  5. Mark dangerous spots with buoys so that sailors can avoid them. Dangerous spots would be borders of parcels with ban lines turned on, parcels with “Object Entry” and/or “Run Scripts” options disabled, blocking obstacles or any other thing affecting navigation on the waterway. Here are a couple of free, one prim copyable and transferable buoys you can use to mark ban lined areas and hazards:
  6. Making a spot where sailors can rezz boats help them after a crash. Ok, nobody wants our properties filled with junk left behind by other residents. However, to minimize the problem you may want to consider splitting your property into different parcels and allow rezzing on the one overlapping a waterway, as explained at point #2.
  7. If you find crashed boats on your parcel, please do not delete them! Rather, return the boat. By deleting the boat or parts of it the owner may loose it. Don’t forget that if the owner of the boat crashed in your parcel, it was likely caused by your ban line or anything else that may have prevented the boat to cross your property.
  8. Do you have a shop? A nice land you want people to visit? Make your land sailor-friendly! Make a small deck where sailors can moor their boats, set autoreturn to zero or allow plenty of time so that people can visit and still find their boats at their return. Place a sign that sailors can see and let them know your land is sailor-friendly. Let the Open Seas Project know, we’ll help promoting it.
  9. If you do change things after reading this, please let us know. Send an IM to the sender of this notecard or one of the group members. You can find our group in Search under “Open Seas Project”.

Thank you for reading this note. Your cooperation on this matter will be greatly appreciated by all the sailing community in Second Life!
