Shortening hull

I was wondering if anyone has shortened the length on an 18’ ? Any thoughts on problems?
Id like 16’. Mahalo

We shortened a widebody down to 20'. Not sure how your proposal will go.

My Jallii Skiff is 16'. Its a little narrower, and hasn't been on the water yet. I took the width and length from the regular, widebody, and Jumbo, plotted a curve, and ended up with a hull thats pretty close to the aluminum skiffs (lund, Lowe, etc) but with 8° deadrise at Transom. I stole the interior and console designs from the CLC peeler. If you want an awesome 16' skiff that is coast guard approved, I would point you towards the peeler. I also have an 16 work skiff I designed, using some of the Tolman tricks. I know that one runs awesome. I can send you my measurements.

I think the more important question is 'why shorter'? I wouldn't change anything from Renn's book. My experience with my widebody was that because the bow is so pointy and stitch and glue is so light compared to poly/glass, Tolmans run and can be powered more like shorter boats. In other words, a 20 ft tolman widebody gets the same engine as a 16 or 18 ft glass deep vee boat; 60-90hp. If your marina/slip has a length restriction, you might try to argue about weight. Most any marina should want as many beautiful Tolmans as they can get!

Are you a Hawaiian waterman! Aloha bruddah.
best,

Leave it at 18 and put a fold away on the trailer. Think my 18 actually measures 17 something.

I believe Dave Wright shortened a standard down to 18ft so I'm sure a widebody is possible as well.

I built an 18 foot Standard and a 21 foot Widebody, all were per the book, no shortening.

If I wanted a 16 foot "Tolman" I'd just do it. I would keep everything exactly the same, just take two feet off the aft end of the stringers. I'd transition from 9 degrees to 8 degrees in the last two feet of the shortened stringers. No big deal and very simple. It's just another boat and nothing to worry about.

Precisely what I did. I installed a folding trailer tongue and installed rubber brake lines. Fits in my shop with 6” to spare.
