Drysuit bouyancy

[FishDiver]

I have been diving a Crushed neoprene drysuit for years and just got a trilam. My guess for the same size the trilam will be less buoyant. Is this accurate and if yes, by how much?

It really depends on undergarments and which two suits. There are floaty trilam style suits and less - floaty neoprene suits. Also, thinner undergarments are typically worn with neoprene suits, so I actually wear less lead in my neoprene.

Rule of thumb for same undergarments? Try a 4# lead decrease to start with. Or dive with the same lead but 4# of it clipped off. Then try handing the weights to your buddy on your safety stop (tanks empty).

Assuming same suit cut and undergarments for now. Four # sounds like a good estimate. I forgot that the neoprene suit is likely to be warmer and may require future undergarment adjustments.

Typically, once undergarments are adjusted for, the weight requirements are the same. Undergarment quality and toe obviously change that.
