Plans Change

After talking with my co-worker, Ted Gauthier about building a boat, he said I should check out Glen-L Marines plans. He also decided to build a boat and settled on the 14 Zip from Glen-L. He said he found the boat for me, the Glen-L Squirt a 10 runabout. I wanted to stick with a small boat since my plan was to build in my basement and the 116" Mustang would make it out of the stairwell based on my measurements. I thought 10 was too small, but it could be stretched 10% to 11. The Squirt looked way cool, so I changed my mind and ordered plans on September 28, 2009 from Glen-L.

The image shown is a Glen-L Squirt stretched to 11 and built by Jeff Cobb of Baton Rouge, LA. He did a suberb job finishing out his boat and its inspirational to see such a fantastic looking boat.




The first step is transferring the lines from the drawing to a layout and assembly board. With a few yardsticks, flexible curves, french curves, circle templates, and large carbon paper purchased from Glen-L, I got the lines down on a 3/4" plywood board.

HP Calculations

In reply to a comment here, I realised I hadnt shown my workings!

So is the 12hp engine powerful enough?

This would be the maximum output.  Its very unlikely my batteries could ever draw this much. The plan is to run the engine at 1500rpm, however it can be run faster if needed.  Why 1500?  well its very quiet at that rpm, but even at 2000rpm its a fraction of the noise at 3000rpm.

This is the horsepower required to achieve this.

This is what I am looking to achieve at 1500rpm

This is the horsepower required.

These calculations are of course in ideal situations with a new engine, however there is still about 33% to play with.

So time will tell, but Im confident the engine will drive it.  Interestingly when I was considering a 1500rpm 4 pole 230v alternator it was calculated by the intended supplier that it could not exceed 3kw output.
