This is the PCGen data set for Fantasy Flight Games Seafarer's Handbook.
This read me file has information to help you use this data set to its
fullest.

Waterproof Scrolls 
To make a waterproof scroll find the base item 'Waterproof scroll' and
create a custom item. Add the spells you wish and the additional cost
will already be included.

Ship construction 
Although it is not yet possible to fully implement the Ship Construction
rules within PCGen you can still handle part of this process using the
equipment tab. The base hulls are included as base items which can be
customized by adding special ship properties. You should rename your
hull to something more descriptive or perhaps with the name of the
vessel. You can then buy sails, oars and anything else you need to equip
the ship. You must calculate the ships speed, HP and other statistics
manually as PCGen cannot do this at this time.
