Is there a way to make a wetsuit less buoyant?

[emoreira]

Buoyancy is directly related to insulation.
Less buoyant means less insulation.
Less insulation means less buoyant.
If insulation is not an issue, use a thinner wetsuit or, as mentioned a wetsuit without legs and arms.

Attach the wetsuit to maybe 10kgs of weights, and a 100m long rope with a buoy in the end.

Throw it into the sea where the depth is 80m+, wait an hour or so, then pull it back up.

Then your suit will have a lot less buoyancy.

Stuff it into a crab trap and sink it down to 200' - 300' and leave it there overnight.
Pull it up the next day and I guarantee it will be paper thin evenly.
The cheap Chinese neoprene they use for suits these days can get ruined by a few good deep dives.

IF you are looking for less buoyancy I would suggest doing what I did. Most divers up here dive 7mm or more. I hate carrying enough lead (≈26#) to get neutral and that much neoprene is very inflexable. Instead I wear a 3mm with layers of neutrally buoyant full suits under the 3mm to get the warmth. By doing that and using steel tanks I only need 12# of lead. Some neutrally buoyant suits are LavaCore and Henderson Polyolefin.

You could iron it.

You guys are really thinking this through!--good answers.
