IOR boat to a cruiser. The boat, Doug Peterson 44&#8242; alum. flush deck, displ 25,000 keel 10,000 , 13&#8217;6&#8243; beam 8&#8242; draft. Built 1978. Intended uses of boat, Mexico and South Pacific.<\/p>\n<p class=\"Body\"> Should I be concerned about the range of stability? If I buy this boat I plan on adding extra tankage low in the hull and under the floorboards if possible.<\/p>\n<p class=\"Body\"> Is there a formula to figure range of stability ?<\/p>\n<p class=\"Body\"> And lastly, I really like the 14&#8242; Wherry pulling dingy. Are they still in production?<\/p>\n<p class=\"Body\"> THANK YOU, Gene <\/p>\n<\/div>\n<p><!--more--><\/p>\n<div class=\"answer\">\n<p class=\"Body\">Hi Gene: Range of stability is a tough one to rough out. You really have only two choices to do it right; go to Doug Peterson and see if he has the data; or two, get an IMS handicap measurement which will work it out for you.<\/p>\n<p class=\"Body\"> In general, early IOR boats tended to be conservative in this regard, but it is always better to get the real numbers.<\/p>\n<p class=\"Body\"> Re: new tankage, the odds are your vertical center of gravity is several inches below the floating waterline, so you will need the fuel low down in the bilge&#8217;s to make it help VCG! Re: Wherries, I am not aware of anyone building these today.<\/p>\n<p class=\"Body\"> Good luck with your project.
