I only point it out because he ought to build to fit his slip.

Bigger than a trailerable.

I've looked at those designs in the past. They do have some nice lines but they are along the same build methods as Glen-L, heavy frames and lots of mechanical fasteners.

Please don't build a Spira. Many of his boats are made with 2x4's, panels don't bend, difficult to build.

I was hoping you'd critique that hull shape more than the framing.

Again, only presented to get Christer to realize....he's gonna need a bigger boat....

... and to avoid the trailerable trap.

The plans Fallguy posted said over 300 feet of 2X4s and I counted 38 sheets of plywood of different thicknesses. To many different size screws to count. But I read on one of the forums that for one of his smaller boat the "fastener" kit was somewhere around $2500. That is a lot of screws! But I bet the boats show up good on radar! :)

At first you showed the DE23 in your choices. That would solve all problems and it is a very nice boat.
There are smaller ones like the P21.

Plus it’s not ugly.

Thanks, I think the P21 is a great boat for that program.

I know I need a bigger boat. Legally trailerable is out the window, now my width constraint is my mooring slip. So, about 10ft wide and 28ft long. 30ft long is a stretch, but might be doable.

I think Jacques posted "Friends don't let friends build a Spira design" in a thread somewhere... :)
8ft dinghy built in 1992, BBV sufferer ever since.

Eastward is doing a cat about that size, I think they were coming in between 100 and 130 rigged.

Building a boat to fit that space is a six figure hobby. It's not for everyone. A boat that maximizes your slip that you can't afford to launch is less fun than a boat you can use.

Most of his hull shapes come from the Sucher books or from the old Texas Dory plans, nothing special.
This one is a flat bottom, beach able dory style (Pacific Dory). They are beachable but they slam.
That hull shape has rocker, it will not plane easily and if it does, it will porpoise and have a bad trim.
The waterplane at the stern is too narrow for planing speeds. That shape is OK for a moderate speed boat, slow semi-displacement.
