Cal 34

I am looking at a Cal 34 76'' model. LOA is 34'', LOD is 33''3" and LWL is 26''. What does LOD stand for? Can anyone give me an idea of the performance of this boat?

LOD means Length on Deck. In traditional terms it is typically measured on the centerline of the boat at the point where the deck meets the stem and the face of the transom. LOA means length over all and traditionally is also referred to as Length between Perpendiculars. In traditional terms it is typically measured on the centerline of the boat at the point where the deck meets the stem and the furthest point of the transom. Boats with traditional transoms should have an equal LOA and LOD but boats with reversed transom rakes will often have longer LOA than LOD.

There are a number of gray zones here. Some designers measure LOA to be the measurement at the top of the toe rail, and would include outboard rudders in the LOA. What should never be included in LOA are such items as bow and stern rails, bowsprits or boomkins but that does not stop unethical brokers and boat builders from doing it.

As to the Cal 34, a 1976 is probably a 2-34 or a Mk III, These were basically updated versions of the 1960''s design. When designed in the 1960''s these were incredibly light and fast boats that offered excellent performance. By the mid- 1970''s these were pretty heavy and quite dated designs. The 2-34 and Mk II are a little improved in a variety of ways but were not especially faster or better performing. With a PHRF rating of 174, these are not especially fast. The Catalina 34 and Hunter 34 of the same era as the MKIII both rate around 150 or a significant 25 seconds a mile faster. Compared to these two the Cal has a very short waterline length that was typical of 1960''s era CCA race rule beaters. This short waterline not only hurts speed but also hurts the boat''s performance and comfort in a chop.

This is a very early fin keel post-hung rudder boat and as such they really do not track at all. In this day of fairly inexpensive autopilots, I am not sure this is as critical as they have a comparatively light helms.

Cals were pretty lightly built for their day and this was in an era where fiberglass engineering was in no as sophisticated as it probably should have been. One of the improvements of the 2-34 and Mk III was a little better engineering. Still it is very important to have the boat carefully engineered.

All of that said, these are boats that I have always liked. They represent a lot of boat with reasonably good sailing abilities for the dollars.

Good Luck
Jeff

LOD stand for length on deck. It usually is a truer measure of the length of a boat than length overall (LOA) because the latter can include almost anything that suits the builder''s fancy, from a bowsprit (useful to know), to how far the pulpit sticks out from the boat.

Sorry, but I know nothing about the Cal 34. Someone else surely will!
