My HT26 Amon-Re has been out of the water for 6 years and the waterline has been lost. Anyone got any ideas as to how to re-establish it.
Neviile Swan NZ.4th January 2008 at 5:44 pm #11620Hi Neville
As our HT 27 is out of the water now I'll take some measurements.I'm not sure if the hulls are of the same hight, but i'll measure also from the ground.
I read somewhere that , you take a long transparent waterhose , lay it on the ground and hang the ends ffrom bow and stern. Then fill the hose with water till the desired hight of the waterline. Then carefully take one end and walk along the hull leaving marks at the waterlevel. Then take the hose to the other hull and repeat this action on the other hull. (don't take one end of the hose from the first hull)
Needless to say that the boat has to stay level otherwise the waterline will be strangelooking in the water.Ps I've just finished scraping off six layers of antifouling to find a thick layup of epoxy anti-osmosis (copper filled for anti fouling) Not a scratch but minor repairs at near the anodes..
I'll add another layer of the same stuff. http://www.ecolinecoatings.com/

Juup7th January 2008 at 6:28 am #11621Thanks Juup. I think your HT27 has 4″ more freeboard, but measurements from the ground ( or keel bottom) would be a great help. Do you know if the waterline is parallel to the keel base? I know of the method using the waterhose but you need a starting point. I thought that I read somewhere that the waterline is 4″ below the bottom of the nacelle but cannot confirm this.
Many thanks, Neville.

I just returned from another day of sanding.
The waterline is from the ground up is 88 cm both bow and stern, but ours is heavy because of twin diesels and fuel and water-tanks.
There was another earlier waterline visible at 86cm from the ground wich may well have been the original. So 87cm will be fine.
But it must be somewhere in that range where your startingpoint to measure the waterline will be.

Will mark it at 87cm and see how that looks. Thanking you.
Neville.17th January 2008 at 8:28 pm #11624Have you got inboards or a single outboard? The inboards need the waterline to be higher so Juup's measurement is OK. Otherwise the waterline will be too high if you have an o/b.
18th January 2008 at 4:51 am #11625Good point, I will bear that in mind as I have the O/B engine.
Neville.2nd February 2008 at 11:37 am #11626Hi, Neville,
On my HT MK1, previous owner had glassed in two 4″ wooden sacrificial keels. ( Cannot think why he completely encased them in Glass Fibre as I would think that this defeats the object.) I didn't notice this and added a 2 inch Iroko keel to each hull. This has increaded the draft by 6 inches, so check whether yours had had any extra bits added on.
