Thames Lighter Instructions


These are simple box structures which can be made to any length (within  reason!). The plan shows a 16" model - just extend the base and sides if you want a longer one. The 16" model shown can just be made out of a 1m sheet of 1/8" balsa, using a small bit of 1/16" for the deck.

If these are to be made for towing, mount a strong towing point on your barge, and seal the end compartments well - possibly using expanded foam. To provide towing weights they can conveniently be filled with water - even when filled to the brim they will still float. For bigger or more robust models, scale them up and make out of marine ply...


1 - Cut out part shapes. Glue the two sides to the base, and attach the ends with the bow and stern formers slotted into position.

2 - mount the crosspieces on each former, and attach the Bow and Stern plates. Check that they are level.

3 - Add the two coaming pieces, and glue the side decks into position.

4 - add a small 1/16" strip around the ends to support the deck and side skins. See the build log on the site. 

5 - Add the bow and stern decks, trimming to fit with the side decks.

6 - pin and glue the end skins into place. If cut as specified acreoss the grain they will bend easily. 

7 - Sand down, apply several coats of sealing paint and decorate to taste.....
