I think I have made one or two errors today. and in consequence am stucK!

10a Ancient former island capital, with a ruined castle built in 1600, now a fishing village
S -A -L - W - Y
12a An old Portuguese or Italian coin
T - S - O - N
29a Light rowing boats used for racing is I think SCULLS
If so 15d would end in a u ALLOTROPU. but should it not be an E so is sculls correct?

Any help much appreciated. Thanks

12a Testoon

Thank you Shells and testoon solve 12 and 29 across. I am not sure about Stornaway as the answer as that would put 2d wrong and I think Thais is correct and also 3d which is I think eelpout.
The letters in 10a at present are s _ a _ l _ w _ y
