Thanks Gregg. Yeah, as this one is display only I could go overboard with the internal bracing.
As for the planking when you're spiling, you're smiling. Ha ha.
Yes, the spare room is starting to fill up with tugs: Kupe (Wellington 1970), Te Matua (Tauranga 1992), Parahaki (Whangarei 1964), Rangi (Otago 1974), Hikurangi (Gisborne 1962), James O'Brien (Westport 1945), Koraki (Picton 1986), Christian Reinauer (NY ATB), St Johns (Florida SDM), Cates X (Vancouver harbour tug) and about 6 half built hulls. As you can imagine my wife is over the moon. Luckily we have several spare rooms so full steam ahead.
