Re: [bolger] Re: Building Nina - Design #196
I anticipate launching much as the beach cats do. The circumstances will depend on the launch site itself and the surf conditions so I can't really give a definitive answer.
But yes, your point is taken, it won't always be easy and there will be times when it will be better just to stay on the beach.
First though, I have to finish the boat.

More questions: How do you imagine, "going through
the surf"? Walking/swimming the boat out past the
breakers and then climbing in? Padle power? Pushing
the boat with a pole? [what is that called?]
What size surf do you expect to cross?
I find it hard to imagine sailing out through the
surf, but maybe...
The prevailing wind on my 'surf' beach is from
offshore, so that would require a closewinded
sail and a diagonal course.

All the frames were at 12" centers. I originally removed every other frame when I turned her over but thought the span for the side decks and cockpit would be to great for a solid platform so ended up putting them back in again. Things can get pretty hectic when there's a big fish on the other end of the line.
There is not much ply left in the frames after all the cut-outs have been made but I would use a 6mm (1/4")ply instead of the 9mm (3/8")ply I used as that was what I had on hand left over from another project. The frames were made up and scarfed together from odd sized pieces. As for the rest of the ply I would use 6mm throughout next time. A lot of the weight also comes from the epoxy coats and the multiple coats of primer and finishing coats of paint.
The strips were cut from some lovely knot-free Douglas Fir floorboards I salvaged from an old house that was being demolished. It must be very old growth because I can hardly count the growth rings they are packed so tightly together. I ripped them at about 7mm thick and after planing and sanding I guess the hull thickness must average out at about 5mm (3/16").
The stripping of the hull was fairly time consuming but I could have saved myself a lot of sanding if I had run the strips through a thicknesser to get them all to a uniform size before gluing them up.
Yes I think you're right about the cuddy to deck fairings. Bolger does hint that Henry Gibson lashed things to it so that might have had something to do with it as well. I didn't think they were worth the extra work as going through the surf is wet work anyway and our waters are warm so no great hardship.
To my mind the little corrugated cover serves as a platform on which to haul out the fish onto as some sort of working space. A 20lb+ cuda flailing around the cockpit with its razor sharp teeth is something to avoid so I'd subdue it with a billy on the platform before bringing it on board. I'm still working on some design ideas for one.
The rudder I'm making is more along the lines of a Hobie cat's rudder shape and I have made the skeg shorter and deeper as Bolger suggested.
I intend making the spars much as per plan but using the "Birdsmouth method". I must admit however that I did think I had the articulating joint that ties the boom and yard together all figured out, but now that it's time to make it I seem to be having more problems than I counted on in its design. That Bolger could design something like that purely from the mental manipulation of parts just amazes me!

I can't figure out the purpose of

Are you building the rudder 'per

use a shallower rudder with a
bottom plate, as he hints at in his

Thanks for the complement Peter
I'm about 15 - 20lbs heavier than the 160lbs Bolger gives but I seriously overbuilt the boat and it should be just about bullet proof if (and when!) I get rolled in the surf.
I intend using the boat in Mozambique and on our KwaZulu-Natal coast to do some fishing but I'm not after big game fish or anything. Mainly spanish mackeral known locally as cuta or cuda and kingfish (trevelley?), garrick etc.
Surf-ski fishing is now an exploding sport but once again Bolger was light years ahead with this design. A little more difficult to get onto the beach perhaps but what comfort by comparison.

I don't know about anyone else, but I'm impressed. She looks very
nice. Do you know how the weight will compare with the original
construction? Are you going big game fishing?

Hello all
I have been busy, off and on over the past two years, building
Bolger's Nina design that I found in his book "Small Boats".
The design was originally made for fibreglass construction so that caused me many hours of head scratching to figure out how to get things done while I was building a wooden version.
For those that might be interested I have posted a few photo's over in the Bolger2 group in the photo section of the progress I've made so far.
As they say, "90% done - 90% to go"
