I have replaced the original two water tanks with one 270 litre keel tank 1.6 metres long leaving space for ballast under the cabin floor adjacent the fridge below the fixed cabin floor. Sailing with the original full water tanks and 200kg of pea shingle she was stiff and sails more upright. With the new tank I reckon on about 250kg of ballast behind the new tank. Can anyone advise the best way to ballast my boat down and will the hull be strong enough to take 250kg concentrated between just forward the bilge sump and the aft edge of my new tank? Should I use cast iron,lead, I can source granite sets, or stick with bags of pea shingle. Particularly I seek advice from anyone who has shored ballast in place and the best way to ensure ballast does not move or indeed grind the hull. My boat seems to be one with all lead shot ballast encapsulated and I do not have fore and aft trim problems. Regards John Pound
Hi John.
I gutted and removed the old tanks. Then rebuilt and added new tanks. In that process I used lighter modern components to reinforce the hull structure. I used the weight I saved by using coosa composite and other lighter weight materials to stiffen the boat. It sails much better know. I know this doesn't address the ballasting issue you describe but what I would propose is to use the "weight" you want to add to the boat to "stiffen" the boat.
I think you'll like it better than just adding dead weight.
