    NC pretty well covers it with the above post. I will however surprise her ........ I have just inspected Shapfell's hull (while checking prop and rudder). Absolutely no sign of osmosis and she is somewhere between 40 and 45 years old (Shapfell is a 25 foot narrow beam GRP cruiser built by Ormelite)

    don't think it's likely to be reversed but there is a lot of agitation "over there" to do away with it totally (for us)

    Blimey !!!!! Just been reading that lot and can feel my eyes beginning to glaze over ! I've got to do a little bit of welding and as I haven't touched my gear for probably 5 years or more (stick/inverter) I think I will just go and play at sticking some bits of scrap together and make sure I have plenty of filler handy to hide the pigeon droppings !!!!! (fortunately it's above the waterline and not load bearing )

    The reason I am familiar with CO2 asphyxiation is from being on fruit carrying cargo ships. Concentrations of CO2 at levels that would cause you to drop almost instantly were very possible in the cargo holds (as well as other gas mixes equally deadly) and strict precautions had to be taken with breathing apparatus worn when ever in those areas. Even so accidents occurred. The other source of CO2 that was sometimes used for specialist cargoes was dry ice. It seems that with CO2 quick removal from the concentration means rapid recovery whereas CO is absorbed by the blood and has to be flushed out

    Wrong again Mike, surprisingly low concentrations of CO2 are hazardous and concentrations of less than 15% are usually fatal http://catalogs.praxairdirect.com/i/27114-safety-precautions-for-carbon-dioxide/16
