Tax Accounting Questiong (and it's a long one...)

Nicki. M., an individual, has started up a charter yacht service (called Starships) and a marina in 2016 in Newport Beach, California, in the same city where Nicki resides. Nicki qualifies to use the cash basis for the charter business.

Certain expenses and capital expenditures relating to 2016 are listed below. The charter business uses the yachts exclusively at the business establishment, and the yachts are used only in connection with Nicki's charter business, Nicki's principal trade. (thus the yachts are not subject to the listed property limitations, also these yachts are the only depreciable personalty put into service in 2016).

The business has a marina buildin, purchased and placed in service on January 3rd, 2016, and five yachts (10 year property), bought new and placed into service on:

Yacht #1, bought for $390,000 on January 8th, 2016

Yacht #2, bought for $420,000 on March 28th, 2016

Yacht #3, bought for $454,000 on June 21st, 2016

Yacht #4, bought for 423,000 on October 2nd, 2016

Yacht #5, bought for $319,000 on Decemeber 8th, 2016

The marina building was bought for $6,600,000 with a down payment of $1,600,000 and the rest from a loan from the bank. The bank loan has an 5% interest rate, and the loan was taken out on January 3rd 2016, and has been outstanding all year long. Only interest was due to be paid on the loan during 2016, and Nicki paid the interest on the last day of each month. In addition, points were required to be paid on the loan, of 2% of the principal, or $100,000 in January 2016. The bank loan will require a $200,000 payment toward principal on January 3rd of each year (starting with 2017) until repaid in 25 years.

An insurance policy covering four years of accident liability was bought for $860,000 on January 3rd, 2016 and Nicki paid for it in full, immediately. Nicki has eleven employees who maintain and crew the ships, each is paid $80,000 a year and each is fully subject to FICA and Medicare. Nicki's business combined FUTA and SUTA rate is 4%. The last paycheck for 2016 will go out on 12/31/2016, and Nicki will deposit the payroll taxes due up til then on that date. Nicki also pays within 2016 all the eomployee's medical insurance annual premiums of $2,300 each.

The real property taxes on the Marina are $370,000 for the 2016 year and will be paid half on 12/10/2016, and the rest on 4/10/2017. The annual personal property taxes on the yachts for the year 2016 will be $5,100 each, and will be paid half each on the same days as the real property taxes. Nicki paid $3,000 each on annual licenses on the yachts when she bought them. Nicki paid $137,000 on December 1st 2016, for fuel and supplies that she got a bulk discount for, she fully expects to use them up between then and May for 2017.

The business gross receipts during 2016 were in excess of $5,000,000 (all from services) and all other allowable business expenses were only about $1,000,000, so Nicki would like to maximize allowable tax deductions, given the facts above what expenses can Nicki claim for 2016?
