In August of 1972 my wife and I chartered a Bristol 25 for two weeks.

was another small boat but it was like the Queen Mary compared to the







Bristol. We did a lot of sailing on the Westerly and once got as far

From a 25 to a 28'







What made the big difference in their performance, Wayne?

Taller mast, bigger and better sails, more efficient keel with less

It also had a much bigger main cabin.







When our kids got to be 5 or 6 we decided it was time for another



bigger boat and we got the Cal-34 that we had for many years. That



was another huge jump in relative size and performance, still small by



the standards of many, but it served us well for a long time.



Understood. Unless something radical it does seem odd that a mere 3 feet can make that big of a difference.



Like going from my 18 ft. Chris Craft to the 23 ft. Marquis.

When you stretch the length of a boat, usually every other dimension

goes up also such as height and width. As a general rule of thumb

the interior volume increases in proportion to the cube of the length.

Let's look at a 25% increase just as an example. We're talking

about the cube of 1.25 (1.25 x 1.25 x 1.25 = 1.95), or almost double

the interior space.

Understood, Wayne. My 22 is a lot bigger boat than my 18, and mt 23 is a lot smaller than my old '27 Chris Cavlier. In this case, just a little bit means a lot.
