inflatable dink question

I was given a ca. 1983 achilles dink. it has a slow leak - that takes about 3 days to deflate the boat by 50%.

It appears to have 3 air chambers - my question is does anyone know typically how the air chambers are configured? are they seperate and continuous - or is on of the chambers a safety chamber that runs thru out the port bow and starbard side. i noticed that when one of the chambers leaks (port side) - it lowers pressure on the starboard side.

thx.

they are probably continuous, otherwise, you'd have to inflate them separately.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

Probably separated. The "other" side lowers pressure as the other de-inflated chamber do not pose internal resistance anymore, relaxing the whole thing. Like Dog says, you have as much chambers as air valves you see.

Exactly. The baffles between chambers are larger than the diameter of the inflated tube so they will move if they don't have pressure from both sides. This is also why you DO NOT want to inflate a chamber fully until ALL chambers have air in them. Put air in all three chambers and then go back and top each of them off.

To find your slow leak mix water and soap in a spray bottle and spray it all over, especially the seams and valves, while inflated and the leak(s) will produce soapy bubbles.


who is staring at the sea is already sailing a little
