Re: [bolger] Re: Green Fishingboat isometric
In a commercial fishing boat, internal cargo capacity and location is
critical. Our permanent home is in northern Minnesota, and I frequently go
down to Duluth and watch the lakers going in and out of the harbor. Their
design is totally focused on carrying massive cargoes of taconite and coal:
bluff plumb bowed stems and sterns, straight plumb sides with no flare. They
travel at length/speed ratios of 0.6, so they don't need fine entries. They
carry the biggest loads that can get through the Soo Locks and over the
shallow channel in Lake Huron. A modern laker looks like a very large Loose
Moose II. A laker and Loose Moose II look the same because the design brief
determines the similarity in morphology.
If this particular fishing boat is not a commercial fisherman but a sports
fishing design meant to carry individuals out into open water, then it's
shape is totally appropriate. Soft riding would be a priority. But if it's
meant to carry a couple tons of fish, I'd like the engine and fuel not to
interfere with that load.

So Fred you prefer something like Shady Lady, Col. Hasler, or the small motor sailer concept boat (the hull form anyway)?
I would guess this boat is faster, for the power. I really like the Robin Jean outboard version. I think it would make a fine pleasure cruiser for most any water, from rivers through the Great Lakes.

I would guess this boat is faster, for the power. I really like the Robin Jean outboard version. I think it would make a fine pleasure cruiser for most any water, from rivers through the Great Lakes.

I think I prefer Bolger's older box keel/cutwater morphology, which doesn't
increase wetted surface or draft over a full-length skeg but provides a fine
entry and place for tankage and engine placement down low and allows for use
of cheap steel ballast at the lowest point on the hull. This present design
probably would ride softer and be quieter going into a chop but it wouldn't
be as useful for interior space utilization as the older designs.
