With a little boat like that I would probably put a centre spine in. It would depend it you're fitting the tank below deck

Right Bit of an update,

Didn’t get to do much over the winter due to the weather and I am having to work completely outside but since the weather has been better I have got some more done.

Bulkheads have all been cut and installed,




I will be putting supports in between the Bulkheads for additional strength. I know looking back these should have been the whole length of the hull but as they will still be tied into the bulkheads they are still going to be a lot stronger than the foam it came with.

Front bulkheads cut for the 91ltr tank to drop into, as well as the floor (tank looks on the pis* in the pics but is straight)






Just now need to get a hole saw the correct size for the ducting to be able to run through the hull and floor, Finish last few bits of glassing under the floor and then flocoat the inside before installing the deck. Then its flip it over and re gel the hull and tidy the outside up

You might want to check with others on this site but I would have concerns about the tank having two point supports ( stringers_) I would be inclined to provided that tank with additional support. Looks like a big job hat is going well.

Cheers.

I am putting a piece between the bulkheads to support the tank so not just on the bulkheads. Just haven't got to that yet. Agree with you don't think it would last long as it is lol

Nice build. Just a taught, are You doing holes in the bulkheads to get possible water trapped there out?

I would, water might get there for one or another reason and then its much nicer when it all will end up in the stern. If Your are filling with foam, no need then.

[1eyedjim]

Yea. Holes in the black tube between the bulkheads so will all run into the middle and to the back where I will be fitting a drain plug

Jim,
any updates? I am about to start myself a sparrowhawk project.

[1eyedjim]

I will do an update one night this week for you. Got sidetracked sorting my other boat but hope to get a load more done weather depending

Really tough little boats and a Yam 90 is the perfect light engine
