Lovely ... but that polished wood won't last long under the assault of the ocean air!

1. Unique possibilities to 25.
2. If e2=1=i3=g5=c8,e1=5,f3=7=b5,b6=2=d7,f7=1,a7=3;left middle box is devoid of 3.Hence e2=5,e1=7,triple 579 at e456;UPs to 51.
3. If h2=6,a9=6,h9=9.Now i5=8 (to avoid the 56 unresolvable rectangle at gh58) and h5 has no candidate.So h2=2.UPs to 81.

1) The dual 13-choice in f7 is resolved as follows: If f7=1, then a7=1, f8=8, f3=7=a1=b5, so in the left center region 2 and 3 should both go into b6. Therefore f7=3. UP 51.

2) The More...
