Hi, i bought a halcyon a few weeks ago and the draught should be 4'0" 1.22m. I measured mine and Icame to 1.42m. Are there Halcyon 27 with diffferent draughts? I also found in the SW-value (kind of handicap system) 2 different draugths: 1.22 and 1.44m

Anyone able to enlighten me?

TIA,

Hi is your rig standard ? standard rig/ballast ratio gives you 1.22 draught . A larger rig needs a greater ballast ratio which also increases draught !

I don't have a clue. Do you have a link to any measurements about standard and larger rigs? I'm trying to get as much info/documentation as possible.

sailboat data has some info but only the standard measurements ! silly question but is there any additional ballast in the bilges ? . Your local sailmaker should be able to give you sail measurements and then you can put your ones against that

Well i measured both the halcyons that are in our yard and they both come in at 122 not including any extra above the waterline like a boot top for example . really not sure where the 140 has come from !
With regard to ballast i spoke to a friend who is a shipwright and he suggested that you would need well in excess of a ton more ballast to achieve 20cm more draught and that possibly your waterline is incorrect .
My own waterline is around 75mm higher than the actual water [wink]

I believe the difference is because of different keels rather than a ballast issue. You need to measure you keel depth and length rather than water line , Bert

Your friend is right Halinda, you would need 1.323 tonnes to increase draft by 200mm, a near impossible task given the bilge space available, bert

I can only go by what I've experienced with "Idris". I've taken loads of weight out of her with regards to emptying all the unnecessary equipment left by previous owners, removing one of the two batteries, toilet, all doors etc. She has also had a very light aluminium Lombardini engine fitted. Her draft barely changed and is still about 1.2m
