Cost to convert to furling sail
Hi Speed Agent,
There are some variables so I'll make some assumptions to deal with them.
The sail has either hanks or the wrong luff tape now, so the luff needs to be stripped and then a new luff tape sewn on. The sail is a cross cut dacron sail. There may also be some modification to the head and tack dealing with setback for the particular furling system you have. #6 luff tape is around $2 per foot. You would multiply this by the luff length of the sail minus a couple of feet and that would be your material cost. To strip and replace the luff with a new tape is two to three man hours depending on length. So, for a 40 foot luff, figure $80for the new tape plus a hundred to two hundred labor.
This does not include any other modifications to the sail you may choose to make. If it is old, and the draft has moved then it may need to be recut. If it is too tall or too short you will have more issues.
