Pete Culler 1840 british cutter for Bruce Northrup, plans

what are the negative things about having all the ballast on the inside

 

Two potential downsides of all inside ballast.

Higher center of gravity which results in decreased stability (assuming same draft and same amount of ballast). Some reproductions of traditional style boats of types which originally had all cargo/ballast inside have been built with at least some ballast outside on the bottom of the keel to meet stability regulations as passenger for hire or school vessels.

If the ballast is not secure it can shift in a knock-down. In a worst case situation the shifted ballast can prevent the boat from recovering.

 

this is the one i was worried about but i can lett a NA look at it and tell me what the minnium ballast is going to be and change the construktion plans acordingly?

 

I doubt Culler's plans include anything about securing inside ballast. That is the type of detail he would have assumed the builder would know.

 

oh sorry i dident finish my post i ment to put the minimum ballast on the outside
