Customer comments regarding tech support provided to customize the Trim and Stability Spreadsheet.  This work involved construction barges with decks that support a crawler crane and it's hook load:

  • “Thanks for the sheets … Thanks for doing this so quickly.  I will be using your services again for sure.”  Steve Haskell, VP, Triton Marine Construction

Customer comments regarding the boilerplate Savitsky Planing boat Excel template:

  • All is good with the template.  I am very impressed by your work.....because ..... it is so clear .... and tidy ...  Very impressive, ... and educated person with a simple mind.   ...  Win van 't Hul, Planing Boat Designer, New Zealand
  • This template is great, I've been interested in the Savitsky's calculative method for a long time.  In fact, I've talked to another professional naval architect, who is also a programmer and software vendor, he said these Savitsky calculations are extremely difficult to set up.  Another experience involves the Abracadabra Race Team.  They hired a very expensive highly technical professional boat designer to do Savitsky calculations.  The race syndicate sure paid him a whole lot more than the asking price for this boilerplate template.   It is my firm opinion that the listed template price for the Savitsky spreadsheet should be way more than the price listed on the website.    ...

  • "I am in the propeller tuning business, and I was looking for software which could give quick powering estimates for planing boats. Thanks to Google I am directed to Hawaii Marine. I ordered the Savitsky template and after receiving it I asked some questions by email. It was Christmas time, so I was ready to wait for some time. But much to my surprise and pleasure I got the complete answers and assistance immediately. The service was superb. ..."
