______________________ MARINER'S DINGHY (7) _______________________

The 'inwales' or internal gunwales are now completed including a new transom block which provides internal strengthening for attaching an outboard motor and enough wooden area to cut in a semicircular sculling hole.

The new internal ribs are now complete with six, 2mm laminations per rib. These ribs have greatly strengthen the hull. I can now move the dinghy around without feeling the hull flex and twist as it has done in the past.

When the central seat or rowing thwart is in place the dinghy will be stronger than it has ever been.
Apart from the added strength to the hull the new ribs will provide fastening points for wooden slats that will make up the new floor.

Solid piece of work. Self-laminating the ribs requires some patience I think. All six laminates at once or one at a time?
Is single ore sculling your specialty or is commonly used in dinghies?

I always mixed enough glue so that I could glue one laminate of wood per rib at a time - four ribs = 4 laminations in total per session - stapled with a staple gun to the laminate underneath it. A bigger mixture of glue would have gone 'off' or hard, so the amount I mixed each time was just enough for the job in hand and just enough to stay liquid enough to use. I would then wait till the next day and then repeat the procedure until I had the required thickness (Six laminations total per rib).

..... single oar sculling is something I learnt to do over 55 years ago. It is a very satisfying way of propelling a dinghy over shorter distances and is simple and easy - one oar, no rowlocks.
