1+23+456+7,890+987+654+32+1=10,044. You add it in bits: 1+23=24; 24+456=480; 480+7,890=8,370; 8,370+987=9,356; 9,356+654=10,011; 10,011+32=10,043; and 10,043+1=10,044.

It appears to be a Beneteau First 456. Best guess--lines are right for that particular boat (style, hull and transom), plus you can see "First 456" on the side of the boat, which fits for that yacht.

The answer is 459. Simply add the numbers together arithmetically as you would for the problem two plus two. To check your work, a calculator is the best option.
