C17 in New Zealand.

Post by OneWayTraffic »

I bought the plywood today. Tunnel greenhouse (plastic tent) is on the way. I am in contact with a shop to order the epoxy (WEST 5:1) and glass. I have ordered a 100metre roll as it's cheaper than ordering piecemeal. I can cut my tape off it.

Some here who remember my post history may recall that I have gone through several ideas on what boat to build. In the end I think I made the sensible choice for the South Island of New Zealand. Capable offshore on the days I'd want to take it out, cabin for bad weather, sleeps two, holds 5 or 6 (if need be) moderate power requirements and not too heavy to tow. I'd still prefer a panga or FS19 for pure fishing, but the cabin will be nice and keep the other half happy.

I will be aiming for the best finish that I can get on the outside. Inside will be workboat: lots of kiwigrip or flowcoat, minimal fairing. I am planning to go for a euro transom (full height frame E for safety.) This allows room on the 6mm ply for a slight stretch of the rear. Hmm.

Congratulations on the beginning!

I look forward to following along.

Beautiful blue on the C17 in your inspiration pic!

Check out the reflections of the spray on the paint. That is some fairing job!

First head scratcher. On the C17 the baseline is the top of the sole. In some of the other designs that I have plans for it is the bottom. D'oh! I was wondering why my stringers wouldn't match the height of the frames. There is about 13mm (1/2") to spare for the notch. I assume I will need to trim to fit later. Or I could lay a strip of 9mm over the stringers and lift the sole a bit.

If things don't seem to fit, and measurements are triple checked, go have a careful look at the drawings!

Just put a strip of ply on top of the stringers, it will be just as strong. Or, raise the stringers cleats by that small difference and fill with epoxy putty. Less work but a little more epoxy.

Thanks. I haven’t actually cut anything yet still drawing out the frames. I have deviated from the nesting a little partly due to the wider transom cut and partly due to not wanting to buy all the 9mm ply up front. I have decided to make the stringers a little higher. There is plenty of room.

I used one sheet of 12mm for two transom layers and motorwell and have got frame E (completely)and D(bottom half) on a sheet of 9mm. Room for frame A on that seconded sheet there if I draw it in two parts. Using my geometry skills!

Not much to report. Almost finished drawing out the panels. The tunnel house arrived, and is partly errected. Cutting out and building the jig is next weeks plan.

Most frames are cut, hull panels tomorrow. I’ll dry install the jig soon with the stringers just screwed together for a check. How much tolerance is there? 3mm (1/8”?) or can things be out more before planing is affected.
