Spira International Custom Boat and Marine Equipment Design

Semi-Custom Boat Designs

Often potential customers ask me if they can have a boat just like your ___ model except ____. Yes, absolutely! I'm happy to redesign parts of my boats or add special features for a small fee. If I think the modified design has merit and would sell as a stock design, I sometimes do this for no charge, and only charge the stock plans price for a modified boat. That's how many of my models have come about. The 17' Kachemak vee bottom dory was such a situation. One customer loved the 19' Hatteras but it was a little too big for him. Likewise the 24' Labrador Grand Banks dory was designed for a customer who first built a 17' Texan Grand Banks Dory, and was considering the 19' Alaskan, but wanted it bigger to carry more load and use it on rougher water. If you have a boat idea, let me know and we'll try to work something out.

Custom Boat and Yacht Designs

I also take on full custom designs for boats. If you'd like a boat designed in any size from 8 feet to 120, I can provide fast professional designs with a strong emphasis on strength. In addition to being an Naval Architect, I'm a degreed mechanical engineer, so have the tools and experience to get it done right for you. Whether you're looking for a custom boat built of wood, fiberglass, steel or aluminum, I can provide the fit, function, and look, you will be proud of and will meet your design needs.

Boatyard and Shipyard Equipment

Whether you need a simple marine railway, s hydraulic lift platform, or the world's largest hydraulic shiplift platform Spira International can supply consulting, design, equipment sourcing, custom equipment and analysis. Even if you only want to build your own small system for hauling you boat out of the water for the season, I can work with you to create a simple, safe and effective technique.

Need hydraulics or marine accessiories? I can help with the design. With over 30 years of practical mechanical engineering experience, I've designed all sorts of equipment for sea water immersion and splash.

Just let me know what you have in-mind.
