1 GENERAL

1.1 GENERAL CONDITIONS

a. It is the intention and spirit of the specifications that the builder shall construct and equip an ocean-going yacht that is ready for use. All articles of equipment, or boat subsystems, furnished by the owner, shall be specially mentioned herein. Omissions from the plans or specifications, or both, of any items, which, according to generally accepted practice, are necessary for the proper operation of the yacht, will not release the builder from supplying the same.

b. The owner or his authorized representative(s) herein called "the owner” shall have access to the yacht and everything pertaining to the yacht at all reasonable times. Every facility will be afforded to inspectors for the prosecution of their work. All handling of material necessary for purpose of inspection shall be at the expense of the builder. A copy of all reports shall be sent to the owner. The materials and manufactured articles of construction of whatever kind, are to be of the best quality for their respective purposes.

C. The workmanship in detail and finish will be first class in all respects and suitable for the purpose intended.

d. Failure on the part of the architect or owner to call attention to defective or improper work or materials will not release the builder from making good such defects when discovered.

e. The yacht will be built under a permanent roof. The builder will protect all work at all times and be responsible and make good any and all damage from whatever cause to any part of the yacht or its equipment, whether supplied by himself or by the owner.

f. The yacht or a part of the yacht has to be delivered according to the terms of the contract between builder and owner.

g. The equipment and construction of the yacht shall meet all requirements of Lloyd's Register of Shipping, or another classification company as agreed between the owner and the builder.

h. The builder shall keep the yacht and materials intended for the yacht, including all items delivered by the owner to the builder, fully covered under a standard builders risk policy of insurance until delivery has been made to the owner. Indemnity for loss, if any, shall be made payable to the builder and the owner as their interest may appear. A copy of the insurance document will be supplied to the owner.

i. Should the architect deems it necessary or advisable during the course of construction to make any changes in the layout or details, so long as the general style and type of the yacht and its arrangements are maintained, such changes are to be made by the builder, without invalidating the contract and without added expense, provided such alterations are determined before the particular part of the work to which they refer to, has commenced.
No charge for extra work will be allowed unless authorized as such in writing by the owner or the architect. No extra work is to be considered as grounds for invalidating the contract or for delaying the time of delivery and completion of the main contract.

j. The builder is at all times obliged to keep the yacht reasonably clean throughout. Particular care has to be taken that all chips, shavings and other foreign matter is removed and that when the yacht is delivered her bilges and pockets are to be entirely free from such matter.

k. After final inspection and when all details of the plan and specifications have been fulfilled, the yacht will be formally delivered to the owner and upon payment of the balance of money still due, the builder shall deliver to the owner all documents showing clear title to the yacht.

l. The specifications and drawings are intended to co operate and any work exhibited in the drawings and not in the specifications or vice versa, has to be executed the same way as if they were mentioned in both. The architect shall furnish the builder with the plans.

m. The builder is encouraged to provide modifications or changes to this specification to his choice as an addition or deduction. All deviations to this specification must be listed and priced separately as an option.

Any additional drawings, which in the opinion of the builder are required, will be prepared by him and submitted to the architect for approval before the work to which they refer has begun. Any and all drawings and specifications prepared by the architect for the purpose of building this yacht, are to remain the property of the architect and he is to be furnished with one copy of all approved additional drawings prepared by the builder.
