Re: [bolger] Re: Blowing up a sea-hawk or inflating, as the case may be.
Mike,
Look at Diablo and Diablo Grande on instantboats.com. If you have
access to Boats With An Open Mind., look at Samuel Clyde. These are
similar to Seahawk.

Because Clyde, I like the lines of the Sea Hawk. The Topaz to my
eye, is an awkward and clumsy design, more suited to please the
farmer's eye than one who has spent much time around water. I don't
mean to ruffle feathers, but designers are like anyone who puts their
pants on one leg at a time. They have good days, and bad days.
I've worked on boats since 1970 and I can say with experience;
graceful, seaworthy boats, are no more expensive and take no more
time to build than ugly boats.
The sweeping sheer, flair of the sides, and the rake of the stem all
combine to make the Sea Hawk dory the power equivalent of Bolger's
Gloucester Dory, the boat he plans to make it into heaven with.
I look at the boat as almost a scale model of a larger boat because
of it's proportions.

This is a little off topic but I would appreciate the
group's opinion. I am restoring an old Monterey
Clipper, strip built of mahogany. She has been 2 1/2
years out of the water and the bilge is very dry. I
would like to put in some kind of anti-rot treatment
now while the strips will really take it up, before I
use a soaker hose outside preparatory to filling the
seams and painting. Any thoughts about what would be
best? Cuprinol? Antifreeze? Borate solution? The
fasteners are all Bronze/brass/copper. The tender for
this boat will be a Bolger design, so it really is a
Bolger question! Thanks. Sam

I'm thinking two layers of 1/2 inch for the bottom and one of 1/2
for the sides. On my model I've put the equivalent of two batterys and
36 gallons of fuel right in front of the transom and the low cabin is
just a place to get out of the rain in. (no galley, bunks, or head.
Also, a steering console just forward of station #5 floats the model
on its lines.I belive the narrowness foward will keep the slamming to
a minimum. This is a fishing boat and not a cruiser
Speed wise, I'm thinking of 20 knots as a maximum. The model seems
to slip through the water at 10-12 very nicely leaving a little extra
horsepower to counter wind and water conditions. If you should happen
to have the book "Small Boats" the top picture of the Sea Hawk is
running with two passengers foward at about the same attitude as my
model does at a scale 12 knots.
You may cause me to rethink the cabin configuration, perhaps a short
deck with an angled vee shaped coaming would be more appropriate.

A few thoughts:
1. Obviously you'd have to increase the thickness of the ply; but
what would you need to use?
2. The centre of buoyancy and centre of the planing surface are not
very far forward in this design i.e. it's fairly narrow forward. This
might make a scaled-up version unsuitable for a fair bit of weight
forward (like a cabin and forward controls). You'd need to make
estimates of weights then calculations of moments vs. buoyancy.
3. Twenty knots in a flat-bottomed boat? OK if you're going to be
using it in flat water. OTOH there are quite a few apparently
successful planing semi-dories around in sizes up to 20' or so.

I've built a 15'6" version of Phil's sea-hawk and I really liked
it's qualities. Except for the size. As stated in "Small Boats" it
truly is more like a 12 footer than a sixteen.
I played around with a model and have done some drawing, and I think
I can multiply the original dimensions by as much as 1.8 to 2.0 and
come up with a long, narrow, trailerable, fishing boat that will have
the same qualities I like in the short version.
I know people like me drive designers crazy, but try to imagine the
sea-hawk as a 31 footer with 8'2" beam, 10 inch washboards, 3 inch
coamings, and a low cabin forward. 50 horsepower should push it about
twenty knots with great mileage. 6 extra frames will give it support,
and two or three stringers will strengthen the side planking.
Think about it and then try shooting holes in my idea, I will
welcome any response that remains civil. (;I'll welcome any uncivil
ones too but I retain the right to be as uncivil as appropriate ;)
