Linthicum is one of the 'best' small lofts around the Middle Atlantic. They are very active in the Philadelphia & Annapolis MD area. Be sure to tell any loft of your (honest) ability as a helmsman, your (honest) expertise in sail 'shaping' and sail 'trim', the typical wind/wave conditions you sail, etc. ... and have the 'cut' adjusted to these parameters - usually all at no 'extra charge'.
FWIW ... but will cost you a wee bit more ... ask for an additional quote (from either loft) to apply an 'over-the-top' leech line system. This will enable you to adjust the leech line from either the leech *OR* from the base of the mast (and in spite of all reef positions. Somewhat important when the boom is over the side when reaching/running and you cant reach out to adjust the leech line, especially in boisterous wind/wave conditions ... simply walk up to the mast and do all the LEECH adjustments from there. You wont have to hang over the life lines reaching out with one hand on the boom and the other one on the leech cord while you hope to hell that your foot doesnt slip .... which may cause you to chin-ups while dangling over the water as a way to get 'back to the boat'. In such an arrangement the leechcord runs up along the leech to a small sewn-on cheek block at the HEAD of the sail thence down along the sail's 'luff' within a small sleeve but 'open' at each reef position ... at the MAST.
If you do a lot of 'rough water' sailing, the over-the-top leech cord is a SAFETY item.
Of course with any 'remote' sail loft *you* should do 'actual' measurements of the mast and boom and 'sail track size'.
